A Simple Desire To Know

Even as a child I seem to have had a strong feeling for what Unamuno has called “the tragic sentiment of life.” … What I had at that time—and it has never left me—was a dream of a reality that we could only touch tangentially, an awe of the numinous of nature whose power rested in its very unattainability.
                                                                  Erwin Chargaff, Heraclitean Fire

As is so often the case, my yearning to partake of the natural world began early in life. I spent a significant portion of my youth in the cloistered wilderness of a quintessentially suburban back yard, observing bees and flies or spiders weaving their webs, completely engrossed. Hearing the evocative calls of white-crowned sparrows, or spotted doves cooing solemnly on foggy mornings, always stirred something inside me—an uplifting serenity. Once, when a hummingbird built her nest on a low branch, I got to watch the whole show, from nest-building to minuscule eggs to first flight. When it was all over, my last visits to the worn out nest (it had been so beautiful) introduced a vague feeling of some unfamiliar kind of loss, the discovery that precious experiences cannot be held onto. The whole experience was a gentle introduction to the hard task of letting go.
Other “life” lessons ensued: the miracle of a butterfly emerging from its chrysalis—that metaphor for transformation so perfectly suited to a child’s mind. There were also witnessed horrors: still-vivid memories of a seething heap of earwigs beneath a moved flower pot and maggots audibly consuming a dead finch. These harsh actualities outweighed by the magical arrival in the night of toadstools on the front lawn, a warbler seen at close range…plants sprouting from the soil, shiny buds that turned into ornate flowers that faded, shriveled, and fell. Also budding, in my wide-open mind, was a vague sense of circularity—that all these things were somehow linked.
Of course, such adult remembrances have inevitably been corrupted by the passage of time and are thus highly suspect. While memories of some events may be accurate, any of the “lessons” that were to have real impact on my later thinking would have been left to incubate further and gather strength. What I do know is that, starting in early childhood, observing living things captured my interest and imagination in ways that playing with friends or watching television did not. Nothing else seemed so real and, by the time I had reached my teens, already of a philosophical bent, I became aware that the answer to certain weighty questions were most likely to be found out of doors.
Anyone who has ended up devoting their life to nature can share similar stories of specific events that had a comparable impact. As for my case: our family took frequent camping trips so I was introduced to mountains, deserts, and seashores early on. (For these trips I am eternally grateful.) Naturally, there was a rock collection. And seashells. My brother, older by three and a half years, became obsessed with birds before he was ten and, once I’d caught his bug, he became my birding mentor. Binoculars for a Christmas present, a gradual accumulation of Peterson Field Guides, the eventual keeping of detailed lists and records.
But what was looking like an inevitable path toward a life in science ended unceremoniously when I abruptly dropped out of college at twenty, troubled by feeling pressured to make what I supposed to be an irrevocable career choice; I had no idea—much less certainty—of what that would entail. Thus ended my “formal” schooling. I chose, without conscious deliberation, to pursue knowledge informally by way of a different kind of institution: the world at large. There I received an education at what I call “the school of gentle nudges.” In lieu of classroom and lab experience there were vivid, sometimes dramatic, real-life lessons. These, of course, did not lead to the credentials I would have otherwise garnered, necessary to bestow legitimate scientific authority. In exchange for a brace of diplomas, a job title and clearly defined occupation, I accepted my lot as humble journeyman naturalist. (While this turned out to be a fair trade I do occasionally regret not having an undergraduate degree in geology.)
Each of my employment choices have been subject to one imperative: that the work allow me to live in a place where I could pursue my true interests according to my native inclinations. Best of all: for two decades, it was my utmost privilege to spend almost half of each year as a backcountry ranger for the U.S. Forest Service. For seventeen summers I lived a genuine fantasy life in an old-timey log cabin boasting a clear view of what was both craggy Sierra crest and the border of Yosemite National Park, with my  cats and horses for company and an array of forest denizens for neighbors. (Some of them, properly speaking, were housemates.) I had what grew to be a sizable natural history library. These circumstances provided the best schooling one of my disposition could ever hope for. While no substitute for the lasting benefits of a university education, I learned a host of things—things that, as is said, “they don’t teach you in school.”
Back to the point: a close study of the natural world conducted in the great laboratory of the outdoors, supplemented by the written word, has lent me a well developed sense of how nature works. But this overall impression proved to be at variance with the one conveyed by my books. In time, this disparity led to a nagging feeling of intellectual unrest. This uneasiness—vague at first but growing steadily as more and more pieces of the puzzle appeared to not fit or were missing—has gradually led to the formulation of a somewhat unorthodox worldview.
            For the most part, I view natural processes through a scientist’s eyes: rationally and dispassionately. And have tried to approach my studies in the spirit of the science’s rigorous standards, filtered through the lens of a particularly robust native skepticism. I have always felt the need to perceive the natural world as a whole and embrace its complexity. Nonetheless, being a naturalist connotes an innate, soulful reverence for nature that can cross the line into mysticism. Thus has it been for me, having always felt a sense of some impenetrable secret at life’s source that is not formally recognized by any branch of the biological sciences. And that proscribed mystical element is simply not tolerated among professional scientists of any stripe.
For as long as I can remember, my mind has rebelled at the purely mechanistic view that considers living things to be machines. In addition, being a generalist rather than a specialist in one field, my approach to nature and understanding of how the whole functions as one have been powerfully influenced by the concept of collective interdependence: not only among living things but between life in its entirety—the whole-Earth biome. Crucial to my way of thinking, I hold that it takes a long and full immersion in the natural world to foster an accurate, broad-brush sense of how it functions. Notably, it matters little if this knowledge is gained with the aid of backpack, microscope, scuba gear, or butterfly net. The hard-won, largely intuitive knowledge acquired by such means is not something that is learned in the lab or conveyed in full through a purely formal education. Eventually, this multifaceted understanding of nature manifests as little more than a elusive feeling, which pervades everything one knows about the world. It influences every thought, attitude, and decision in one’s work or study. It is an intellectual medium, a gift, and a font of unlimited enchantment.
 In a letter to a student, a certain well-known physicist wrote, “The deeper we penetrate and the more extensive and embracing our theories become, the less empirical knowledge is needed to determine those theories.” While recognizing that the context of his statement is not the same, I have reached a conclusion that echoes Einstein’s sentiments—that a profound comprehension of nature’s wholeness cannot be expressed in words or directly conveyed. It represents the sum total of the devotee’s knowledge and experience and amounts to an intuitive understanding not constrained by normal conceptual modes. As such, it cannot be precisely the same for any two people; each individual will be obliged to approach, by partially non-logical means, a representation of reality somewhat beyond the sphere of empiricism. Another way to express this notion: any dedicated attempt to understand life in its fullness calls for the mind of a scientist, an artist’s heart, comfort with paradox, and freedom to admit uncertainty.
For years, these ideas simmered over a gentle flame. It was only after I began to more seriously take on subjects such as evolution, genetics, and origin of life theories that my views on the precise nature of life began to coalesce into a full-flavored philosophic stance. I increasingly discovered that things I had long assumed to be true were in fact at odds with conventional views—most conspicuously, that there was something about life that remains outside the sphere of empirical science. Some of my older beliefs, revealed to be erroneous, were discarded like worn-out clothing. Still, it became glaringly obvious that few educated people—scientists and nonscientists alike—perceived life as having any sort of causal agency unto itself. But it was only after I began a systematic study that my private take on what life actually is began to coalesce.
It bears mentioning that these matters have long been something of a personal fixation. I find it difficult not to ponder—bordering obsessively—the “meaning” behind the countless faces of nature. My mind turns to such matters, in some form or another, on a daily basis. Often, all that is required is a brief glimpse of an insect, a pause to admire the intricacy of a leaf, or the sight of a familiar landscape. Instantly, I feel myself washed by a wordless, almost prayerful appreciation with a question mark and exclamation point tacked on. While impossible to express in words, I would say that the sensation could be akin to (but much less dramatic than) what is depicted as “seeing one’s life flash before their eyes” when death is imminent. Or: it is like seeing a parade of unknown faces pass in an instant before my minds eye. (This I have experienced on occasion.) There is a powerful and bittersweet sense of knowing, but being unable to grasp, the final truth—like trying to pull up a dream image as it inexorably fades and is gone. I have no idea if others experience something similar. But it befalls me frequently. 
As time passes, my personal impression of how nature operates, and what life consists of, continues to evolve and change. (It has been quite a pleasant surprise to see just how much.) At the same time, my particular brand of understanding—my very mode of thinking—leaves me somewhat intellectually marooned as, more and more, I find classical western thought on certain subjects either wanting or just plain wrong. Above all, our basic concept of life is entirely inadequate, needlessly constrained by a narrowed view of its almost boundless capabilities. I feel strongly that many of the limitations imposed upon how we perceive nature are simply due to semantic shortcomings. We lack a range of nuanced terms for describing subtler features of living matter. 
A conceptual damn broke, for me, upon realizing that what was missing was a frank admission that the living world, while obeying all physical and chemical laws, is at the same time an incomparable process with nebulous or ill-defined attributes—these being mingled with life’s concrete material properties. Insofar as we have a mistaken view of what life consists of in its wholeness, that limited view is the result of having formed a predominantly materialistic conception—one that cannot adequately encompass certain inherently subjective or blurred features. A sort of cognitive dissonance is one consequence of this dichotomy. The resulting tension is rooted in the conflict between a material, mechanistic perspective and one that credits life‘s powers of agency and inventive creativity. The former has led to what I consider to be a glib certitude with rather bleak undertones. The latter contains within it a recognition of something glorious beyond words. And with this recognition of life’s innate intelligence comes the humility that is a side-effect of admitting ignorance of things beyond human ken. 
I have little difficulty imagining a world without consciousness, without “us.” Nature would proceed apace—the mouse heedlessly nibbling grass seeds in a meadow, the hawk unthinkingly nibbling the mouse in turn with neither concern nor savor. But, for us to be here, able to witness and appreciate such splendor: in a manner of speaking, the world is much better for it. Richer. Whether or not our existence (or that of something like humankind) is “needed”—or even required—remains an open question. 
Philosopher Thomas Nagel neatly expresses my own position when he writes, “there may be a completely different type of systematic account of nature, one that makes [use of] neither brute facts that are beyond explanation nor the products of divine intervention. That, at any rate, is my ungrounded intellectual preference.” I have  a similarly “ungrounded intellectual preference.” With no ideological axe to grind and no prevailing philosophy or religion to uphold, I simply wish to know, insofar as my limited capacities will permit, why our world is the way it is.

Piute Log...I Hate Fremont Lake 2001

4 Aug (Sat)     Rode to Fremont Lake on Red. Zack, I’ve discovered, hates to be alone. When I left him locked up in the corral on Wednesday he stood at its gate rails all day and dug a big hole. So today I let him out. ◦◦◦◦◦ Had a shovel cached at the junction. Worked up the hill cleaning WBs and throwing many stones. Heaving a big boulder off the edge of the tread I looked up and saw Ray Benson, brother of Jeff (who worked in our Rec[reation] Department for years, since moved on) and his wife, Nancy. I’d never met her before but have seen Ray a number of times. “You caught me working!” We had a nice visit. Windy all day again and the dust was horrible with all my frenzied shoveling. ◦◦◦◦◦ Only a few small parties at the lake. But—uh oh!—two older men with one horse tied between trees with two lead ropes so’s she could hardly move. She was already pawing. (Who wouldn’t be?) Sure sign of impending disaster. I gave them various hints and suggestions but it was late and I was too tired to deal with nimrods, et cet. ◦◦◦◦◦ Stashed the shovel and headed home. Found that Zack had spent most of the day parked at the front gate as evidenced by a big, dusty pit full of churned-up manure. Oh, well, another neurotic horse. Even more irritating: after hauling sand the other day I left the wheelbarrow “parked” near the south wall of the cabin. Zack had come over and took a big dump right in it and, in addition, had scraped and pawed all around, casting sand into it as well. A classic illustration of horsey-mentality. They have their ways of getting even, like Fat Freddy’s cat pissing in Fat Freddy’s boots. ◦◦◦◦◦ BBQed my last steak, somewhat far gone since all my ice melted two days ago but marinating revived it somewhat. (Wasn’t about to throw the thing out, no way.)

5 Aug (Sun)     Woke up at 5:30 and went outside to see Venus and Jupiter blazing away, within about 1–2° of each other (that’s really close). Quite a sight. 36° on the porch (Fahrenheit, that is.) ◦◦◦◦◦ Quite frankly, I despise Fremont Lake. I hate to go there…don’t fish and I don’t find it attractive, buried in its hole, and although it isn’t as crowded as years past, only bad things happen there. Yesterday I found a new pit full of garbage—foil, cans, burned clothing, and batteries—built on a slab with the remains of a busted-up, rotten log scattered around. The first “legal;” site, as you come around the lake, had a big stack of terrible firewood—fresh-cut green branches, chunks of rotten log, and a log “bench” whose end was charred from a late-night out-of-wood attempt to keep the fire going. A real abortion. The pit had been covered over with blackened rocks, rendering it ugly and useless. Coals strewn around the blackened earth. These things flat-out sicken my spirit. So I avoid the place. Like most rangers, I prefer the lengthy and scenic patrols into the high country. ◦◦◦◦◦ But…my conscience (such as it is) was on my case this morning. Those foul firepits…and, did those guys leave that poor horse tethered between the two trees all night? So, I went back. ◦◦◦◦◦ When I got there the two men were out on the lake in their tiny rafts. There was plastic and paper in their pit (I’d just explained to them about that—“Wind blows it into the bushes…please just put it in a sack,” et cet—and they’d completely ignored my advice. The poor, lonely mare was indeed still tethered and had dug a crater an honest foot deep—duff and dust scattered far—and she was clearly in distress. I felt a cellular outrage. To vent, I tore out two of the ugly, aforementioned pits and waited for the two men’s return, making speeches in my head. ◦◦◦◦◦ The owner of the horse was completely taken aback that I was upset. He’d brought feed—about 2 pounds of grain—and said, quote, “I wasted an hour this morning letting her graze.” (There’s NO grass around the lake to speak of.) I could go on but, in short, I spent about an hour and a half with these two city beaters. Read out of the copy of the Backcountry Horseman’s Guide (which I then gave them), took them on a tour of the local destruction, had them move camp and horse to Bart’s basecamp site and lent them my shovel to fill in the ditch. I was ready to write two citations but relented when it became obvious that they were “innocent”—e.g., clueless—and really did want to be good campers. I told them, “I don’t want to write you a ticket. What I want is to change your behavior.” They both swore that I’d gotten through. Sure hope so. ◦◦◦◦◦ Tore out that foul condo [gigantic firepit with added layers of ash, coals, and rocks] on the east shore; one of those sites where you can’t dig a hole without running into buried coals from past clean-ups. A big, ugly job in the hot sun. Found new, old dumps of broken glass nearby and filled up a couple of plastic grocery bags with glass, foil bits, rusty cans and food wrappers. I’ll tell ya: I paid my rangerly dues today to make up for those sweet, long rides and peak bagging sprees earlier this week. And there was no one else at the lake to see me sweating. Rode home slow and took a nap. I’d left Zack in the round corral today, hobbled. All in all, I felt better…none of my labors today will ever be noticed and the pits will literally grow from the ashes again and be filled with trash. But I know

The Demeaning of Life...Chapter 3. Evolutionary Theory and the Modern Synthesis


Now one could say, at the risk of some superficiality, that there exist principally two types of scientists. The ones, and they are rare, wish to understand the world, to know nature; the others, much more frequent, wish to explain it. The first are searching for truth, often with the knowledge that they will not attain it; the second strive for plausibility, for the achievement of an intellectually consistent, and hence successful, view of the world. To the ones, nature reveals itself in lyrical intensity, to the others in logical clarity, and they are the masters of the world.
                          Erwin Chargaff, Preface to a Grammar of Biology (1971)
An important corollary of Natural Design is that modern evolutionary theory is lacking in key regards, contrary to the widespread belief that our understanding of evolution is now complete in all but its finest details. This is not the case; Darwin himself had no idea how complex and multifaceted the matter was and key parts of his theory, long admired and cherished for their elegant simplicity and indisputable truth, have over time evolved and undergone adaptation. For instance, the role of natural selection—the most fundamental aspect of Darwin’s theory—is being revisited and its status as evolution’s primary driver called into question. (It is now accepted belief that several factors are at work, each of which is subject to selective pressures.) As well, by the time Darwin’s ideas had gained widespread acceptance, no one had yet given serious thought to the evolution of physiological processes and systems. Complex biomolecules such as DNA, unknown at the time, also have evolutionary histories. Natural Design offers a new angle on such matters. 
Before tackling these convoluted topics, a historical overview of how modern evolutionary theory took shape will provide useful perspective. This will be followed by a look into scientific materialism—a stance based on the assumption that all phenomena are solely the result of physical (“material”) matter being acted on by natural laws, nothing more—and how this approach became the basis for all scientific methodology. Again, this is pertinent to the Natural Design viewpoint. 
The two bedrock assumptions that Darwin’s theory of evolution by natural selection is founded on are that there can be random variations in genetic material (mutations) which can lead to adaptations that in turn might improve an organism’s chances of survival. The late paleontologist and evolutionary biologist Stephen Jay Gould, summarizing its main tenets: “First, that all organisms produce more offspring than can possibly survive; second, that all organisms within a species vary, one from the other; third, that at least some of this variation is inherited by offspring. From these three facts, we infer the principal of natural selection: since only some of the offspring can survive, on average the survivors will be those variants that, by good fortune, are better adapted to changing local environments. Since these offspring will inherit the favorable variations of their parents, organisms of the next generation will, on average, become better adapted to local conditions.”  
During the two decades Charles Darwin spent working out his ground-breaking theory, neither he nor any of his peers had any idea how unimaginably complex the manifold workings of life actually were. As an illustration of how little was understood it that era: German biologist Ernst Haeckel, a contemporary and great admirer of Darwin’s, believed that the cell (still a little-known entity) was “not composed of any organs at all, but consist[ed] entirely of shapeless, simple, homogeneous matter…nothing more than a shapeless, mobile, little lump of mucus or slime….”
While Darwin was slowly and meticulously refining his ideas following the voyage of the Beagle, a congenial and self-effacing Austrian friar was growing pea plants in his abbey’s garden. Over the course of eight years, Gregor Mendel patiently reared almost 30,000 plants while piecing together the foundation of modern genetics.[1
Due to a number of adverse historical circumstances, Mendel’s far-reaching insights went unrecognized for nearly half a century. Significantly, after all his painstaking labor and meticulous recording of data, the priest’s findings were made known solely through two public lectures followed by a paper submitted to the Proceedings of the Natural Science Society of Brünn. Aside from that one obscure 1866 publication, Mendel personally distributed 40 reprints of the treatise to suitable people and…his seminal research quickly all but disappeared. It was ignored by fellow botanists, who found themselves confused about the object of it all. They perceived the work as being merely about hybridization (animal breeding and horticulture being a feature of their day-to-day lives), and were put off by Mendel’s perplexing reliance on numbers. While this might seem odd today, scientifically rigorous experimentation involving statistics was a foreign concept to biologists of that era.
Mendel’s efforts were largely forgotten until 1900, when three European plant physiologists, independently performing similar experiments, simultaneously brought to light the friar’s enormous contribution to science. Mendel’s treatise Experiments with Plant Hybrids had been published seven years after the first edition of On the Origin of Species came out but, despite an apocryphal story that Darwin owned a copy but never read it, there is no evidence he was aware of the work.[2] (Many scholars believe that Darwin, whose mathematical skills were poor, in all likelihood would not have recognized its implications.) Mendel, long in poor health, died at only sixty-one. All his papers, all his scrupulous documentation, were carted out to a hill behind the abbey shortly after his death and unceremoniously burned.[3]  
Once brought to light, Mendel’s ideas rapidly gained traction. Early geneticists debated a growing number of conflicts with Darwinian precepts. These were based in part on the realization that Mendel’s laws had shown that inheritence was a material affair that could be tested by experiment, not the result of Darwin’s more abstract and somewhat nebulous selective process. Many believed that traits were inherited in the form of discrete units, which could be accounted for by the newly discovered phenomenon of mutation (rather than a measured blending as called for by natural selection).
The discovery of genes as “particulate” units of inheritance had a huge effect on accelerating evolutionary research. In the 1920s and 30s, following the acceptance of chromosome theory, a new discipline emerged: population genetics (the study, heavy on statistical analysis, of how traits arise and move through populations). Thanks largely to work by two Britons—statistician Ronald Fischer and biologist J.B.S. Haldane—and American geneticist Sewall Wright, Mendelian genetics and the concept of evolution by natural selection were finally integrated: a unification that became feasible only after it was finally recognized that the gradual, steady modification central to Darwin’s theory was entirely compatible with Mendel’s axioms. This paved a way to resolve various disputes that had been intensifying for some time.
These conflicts were for the most part put to rest during the course of an international symposium held at Princeton in 1947, shortly after WW II’s travel restrictions had lifted. It became known as the modern Darwinian synthesis. The synthesis was basically a set of ideas that were assertively championed by bird taxonomist-cum-evolutionary biologist Ernst Mayr and several of his chief collaborators in America, notably paleontologist George Gaylord Simpson, expatriate Soviet  geneticist Theodosius Dobzhansky, and botanist G. Ledyard Stebbins—all prominent experts in their fields. In England, well-known biologist and science popularizer Julian Huxley (grandson of Thomas, “Darwin’s bulldog) used his public visibility to spread the word, in particular in promoting his vision of human progress through evolution.
Up until that time, researchers working in disciplines such as paleontology,    systematics, and natural history were neither in close communication nor sharing their findings. To some extent, these areas were all influenced by Darwinian theory (even though many of his ideas had long since fallen out of favor). The specific disciplines’ views on evolutionary agencies and their relative importance had diverged; each was starting to attribute different meanings to established concepts and use different terminology to describe them. Some had even formed their own evolutionary theories. Population-level thinking had not yet taken hold. Of even greater concern, paleontologists were actually at odds with the concept of natural selection—a consequence of not seeing the gradual changes required by its precepts reflected in their established fossil records. Those working with population genetics were convinced they had finally found a way to connect the different disciplines.
The symposium, considered a great success, united many branches of biology under one common evolutionary umbrella that (according to Gould) “validated natural selection as a powerful causative agent and raised it from a former status as one of a contender among many to a central position among mechanisms of change.” This had been the gathering’s intended goal. Mayr made clear that the intention of the synthesis was no less than a means to designate the general acceptance of two conclusions: gradual evolution can be explained in terms of small genetic changes (‘mutations’) and recombination, and the ordering of this genetic variation by natural selection; and the observed evolutionary phenomena, particularly macroevolutionary processes and speciation, can be explained in a manner that is consistent with known genetic mechanisms.”
The true significance and influence of natural selection was still being debated until Dobzhansky reaffirmed its primacy with the publication of his book Genetics and the Origin of Species in 1937—a critical, solidifying event in the movement’s early development.[4] The alliance thereafter commonly became known as “the synthesis” (although, in time it became known—somewhat erroneously—as neo-Darwinism.[5]) However, like Darwin and his contemporaries, Mayr and his esteemed colleagues had little notion of the real complexities lying beneath the surface of their various disciplines. Microbiology was in its infancy and the helical structure of DNA was yet to be revealed. No botanists ecologists, or embryologists had attended the symposium and new findings in those fields and others would muddy the water for years to come.
Due in part to the strong personalities and fervor of neo-Darwinism’s promoters, from its outset the movement was infused with a zealousness that made it notably resistant to change—an ironic misfortune, since all the scientific branches concerned were in flux. By the 1950s the movement started to move away from the pluralism of the 1930s and 40s in favor of an almost complete emphasis on adaptationism (the view that many traits are the result of evolution through natural selection). The synthesis entered a phase of intellectual rigidity—what Gould later christened “the hardening.” What had set out as a collaborative integration began to exclude and marginalize.
The following decades witnessed a flood of new information and ideas, some of which received a great deal of resistance. Only fifty years later, leading experts became increasingly aware that the modern synthesis was in serious need of modernization. While it has taken time, it is now becoming widely recognized that evolutionary theory is a considerably less straightforward matter than was previously assumed, with problematic questions still surfacing. For one thing, we now know that natural selection is but one of a number of influences driving the whole process. Also, during this same period there has been a parallel broadening of perspective with regard to the evolutionary aspects of all branches of biology. Thanks to the arcane strangeness of quantum theory, a growing understanding of the microscopic realm, and the newly revealed universe of the cell, we have arrived at a more sophisticated appreciation of nature’s subtleties and complexities. The entire framework of the way we view life has shifted. But it remains a work in progress.

[1] Properly speaking, Mendel was from Moravia, a historic region in what is now the Czech Republic. Many misconceptions surround Mendel and his work: for one, he was a friar—not a monk—and  lived not at a monastery but at an abbey, among a community of very talented and learned men. (Moravia, in the early 1800s, was ahead of its time in promoting the power of science in order to improve social and economic conditions and was a region known for its advanced animal breeding and horticulture.) Another thing: it was a happy coincidence that Mendel chose to work with pea plants. He had no way of knowing that the traits he chose to follow were controlled by genes found on different chromosomes and those traits also happened to denote distinct, unambiguous features not typically displayed in such regular fashion.
[2] Mendel and his peers were well-acquainted with Darwin’s work. (Mendel had a well-worn copy of Origin.)
[3] The complicated story of the simultaneous “rediscovery” of Mendel’s research is somewhat out of the scope of this work but quite intriguing. Mendel’s obscure publication had been passed around by a few plant breeders. Among those who had read the paper were Dutchman Hugo de Vries, German Carl Correns, and Austrian Erich von Tschermak. Working independently, each achieved in their own experiments results similar to Mendel’s. Correns barely missed out on beating de Vries to publication and there is evidence that both intended to claim discovery of what became known as Mendel’s Law (the 3:1 ratio of dominant versus recessive characteristics generated by the hybridization of two purebred strains). Coincidently, de Vries sent Correns a copy of his newly published article, written for a French journal, that made no mention of Mendel. Correns was just then putting the last touches on his own manuscript and, bitter at having been upstaged, hurriedly finished his own paper and sent it to the German Botanical Society for publication. Correns made a point of crediting Mendel with the 3:1 law’s discovery to undercut de Vries’ claim to priority; whether or not he intended to do the same is still debated. But, unbeknownst to       Correns, de Vries had already sent his paper to the German Botanical Society and, in this version, had credited Mendel. Thus was Mendel’s work rediscovered and handed over to science.
[4] Dobzhansky was the first geneticist to work in the field with natural populations. He “helped to establish population genetics as the empirical field that provided the long-missing piece to the original Darwinian puzzle.” 
[5] George Romanes, a protégé of Darwin’s, “coined the term neo-Darwinism to refer to the version of evolution advocated by Alfred Russell Wallace and August Weismann with its heavy dependence on natural selection…[rejecting] the Lamarckian idea of inheritance of acquired characteristics” (a commonly held notion of the era that Darwin himself had embraced).
