The Darwinian Revolution




Charles Darwin’s theory of Descent with Modification through Mutation, Adaptation, Natural Selection and Speciation in his November 1859 book On the Origin of Species was not a revolution in and of itself, but rather the keystone to a scientific revolution that had begun nearly four centuries earlier. The Scientific Revolution was not a ‘revolution’ as that term is commonly colloquially conceptualized. Whenever the overwhelmingly vast majority of the lay public hears and reads the term ‘revolution’, what immediately springs to one’s mind are the American Revolution of 1765, the French Revolution of 1789, the German and Italian Revolutions of 1848, the Russian Revolution of 1917 and the Spanish Revolution of 1936. The one thing that all of these sociopolitical revolutions shared amongst them is that they all took place on a time scale of days to years. The Scientific Revolution, by contrast, is more comparable to the Neolithic Revolution of the 11th millennium BCE, which took place on a time scale of centuries—not years, but hundreds of years.
Third President of the United States Thomas Jefferson enumerated the ideological and philosophical impetus behind the American and French Revolutions of the late 18th century in the Declaration of Independence in June 1776:
We hold these Truths to be self-evident: that all Men are created equal; that they are endowed by their creator with inherent and certain inalienable rights; that among these are life, liberty and the pursuit of happiness: that to secure these rights, governments are instituted among men, deriving their just powers from the consent of the governed; that whenever any form of government becomes destructive of these ends, it is the right of the people to alter or abolish it and to institute new government, laying it's foundation on such principles and organizing it's powers in such form, as to them shall seem most likely to effect their safety and happiness.”[1]

            The philosophical underpinnings of the scientific revolution were perhaps best articulated by the late great Cornell cosmologist Carl Sagan in his 1994 book Pale Blue Dot: A Vision of the Human Future in Space:
From this distant vantage point, the Earth might not seem of any particular interest…The Earth is a very small stage in a vast cosmic arena…Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves…There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world.”[2]

            The process of challenging the conceit that humans have a privileged place in the universe began with late Fifteenth Century Renaissance Polish astronomer Nicolaus Copernicus, who formulated a heliocentric model of the known cosmos, now known as the solar system, which placed the sun as the center of it around which everything else orbits rather than the Earth. The geocentric model Copernicus was challenging is not only featured in the Judeo-Christian Bible, but dates back to the 7th century BCE Ancient Greek philosopher Anaximandros and, perhaps most famously, the Fourth Century BCE Greek scientist Aristotle. One reason why the Aristotelian geocentric cosmos was featured in the Christian Bible, written in the late Fourth Century CE, even after the heliocentric model was first proposed by the Greek astronomer Aristarchus in the Third Century BCE, was due in no small part to the Christian church’s interpretation, evident in the Bible, that it fit in with their belief that the Judeo-Christian god of the Bible would create his favored race, humans, on a planet placed at the center of his creation. This, in turn, fed into what Sagan calls “the delusion that we have some privileged position in the universe”.
Another delusion of human exceptionalism that was to be dispelled in the Scientific Revolution was established by 16th century Irish Archbishop James Ussher, and ironically enough by 17th century German astronomer Johannes Kepler and English physicist Sir Isaac Newton. In his ‘Annales Veteris Testamenti, A Prima Mundi Origine Deducti [Latin: ‘Annals of the Old Testament, Deduced From the First Origins of the World’], Ussher wrote that Verse 1 of Chapter 1 of the Book of Genesis [“In the beginning, God created the universe.”] took place in the year 4004 BCE, writing:
I deduce that the time from the creation until midnight, January 1, 1 AD was 4003 years, seventy days and six hours.[3] [Six hours before midnight would be 6:00 PM] … In the beginning God created heaven and Earth, Gen. 1, v. 1. Which beginning of time, according to our Chronology, fell upon the entrance of the night preceding the twenty-third day of October in the year of the Julian Period 710. The year before Christ 4004.”[4]

            Kepler calculated the date of Genesis 1:1 to not October 23, 4004 BCE but April 27, 4977 BCE. Newton was obsessed with Biblical numerology, having calculated in 1704 that the world-ending apocalyptic battle of Armageddon depicted in Verse 16 of Chapter 16 of the Book of Revelation [“And he shall gather them to the place called in Hebrew ‘Megiddo’.”[5]] would take place in 2060. Newton also calculated the year of the creation account in the Book of Genesis: 4000 BCE.
            Once again it is not difficult to conceptualize the reason why these dates would have appealed to those who believed in the Judeo-Christian Biblical account of humans as god’s chosen species, as they coincide closely with the beginning of known recorded history. The earliest writing system in Europe, the Vinca-Turdas script [from the Turdas-Vinca culture, discovered in Turdas, Romania by Hungarian anthropologist and archaeologist Zsofia Torma in 1875 and at Vinca-Belo Brdo in Vinca, Belgrade, Serbia by Serbian archaeologist Miloje Vasic of the University of Belgrade in 1908] has been carbon dated to between 4500 BCE and 4000 BCE.[6] The earliest evidence of the Harappan script of the Indus Valley civilization dates to 3500 BCE[7] as does that of the Cuneiform writing system of Sumeria in Mesopotamia[8]. The desire to imagine behaviorally modern humans as being the focus of the creation of the universe makes placing the date for the beginning of the universe at or near to the date of the beginning of human history naturally enticing.
Ironically, the process of unraveling this comfortable delusion was begun by a man whom the Christian Church would later beatify and canonize as a Saint: Vacariate Apostolic of Northern Germany Nicolaus Stenonius, Titular Bishop of Titiopolis, Isauria, Asia Minor. A 17th century Danish scientist, born Niels Steensen in Copenhagen in 1638, he was the first to propose, in his 1669 ‘De Solido Intra Solidum Naturaliter Contento Dissertationis Prodromus’ [‘Preliminary Discourse to a Dissertation on a Solid Body Naturally Contained Within a Solid’], the concept of ‘deep time’ that 18th  century Scottish geologist James Hutton and British geologist Charles Lyell would later formulate into the theory of uniformitarianism. Stenonius established the field of stratigraphy with his Principle of Superposition, which states that, within a series of stratigraphic sequences, the upper units of stratification are younger and the oldest strata will be at the bottom of the sequence. He also established the Law of Lateral Continuity, which states that rocks that are otherwise similar but are now separated by a feature can be assumed to be originally continuous, or as Stenonius wrote “Material forming any stratum were continuous over the surface of the Earth unless some other bodies stood in the way.”  This latter law led late 18th century English geologist William Smith to the conclusion, dubbed the law of faunal succession in his 1815 geological map of Great Britain, that if layers of rock at differing locations contained similar fossils, then the layers were the same age.[9] This, in turn, led Smith’s nephew and student, English geologist John Phillips, to calculate in 1860 that the Earth must be at least 96 million years old.[10]
In 1864, Scottish-Irish physicist William Thomson, 1st Right Honorable Lord Kelvin, who formulated the First and Second Laws of Thermodynamics, calculated the age of the Earth based on the Earth’s internal temperature to between 20 and 400 million years, writing “This Earth, certainly a moderate number of millions of years ago, was a red-hot globe” too hot to support life.[11] In his book On the Origin of Species in 1859, English geologist Charles Darwin calculated, based on the erosion rate [assumed to be around 1 inch every hundred years] of the chalk escarpments of the North and South Downs and the sandstone High Weald and clay Low Weald of Southeast England, that the Earth must be at least 300 million years old. [It should be noted for the record that Darwin was off on his calculation of the ages of the Southeastern England Wealds by a factor of ten times, as more modern methods showed them to be between twenty and thirty million years old; and that, in response to criticism from Thompson, Darwin removed all reference to the Wealds from his 1861 third edition of Origin of Species].[12] 
However, in Origin of Species Darwin used this calculation as the time frame for his Law of Natural Selection, part of the theory of evolution that would provide the final proverbial nail in the coffin of the Judeo-Christian dogmatic doctrine of human exceptionalism.
Verse 7 of Chapter 2 of the Book of Genesis states that humans were the first creature created. Verses 19 and 20 go on to say that thereafter as each creature was created, humans gave to them their names. However, the man responsible for giving the species of animals and plants the names that scientists know them by played a pivotal role in the paradigm shift by which Darwinian Natural Selection would topple the delusion of human exceptionalism once and for all. Eighteenth Century Swedish zoologist Carolus Linnaeus, the father of modern taxonomy, in his 1735 ‘Systema Naturae Per Regna Tria Naturae, Secundum Classes, Ordines, Genera, Species, Cum Characteribus, Differentiis, Synonymis, Locis’ [Latin: ‘System of Nature Through the Three Kingdoms of Nature, According to Classes, Orders, Genera and Species, with Characters, Differences, Synonyms, Places’], developed the concept of binomial nomenclature cladistic classification. Linnaeus was the first to classify humans by their scientific species name, “Homo Sapiens”, and classify them as a species of Hominid, members of the phylogenetic Family “Hominidae”, commonly colloquially called ‘Great Apes’. Along with our fellow Hominids “Pan Paniscus” [Bonobos], “Pan Troglodytes” [Chimpanzees], Gorillas and Orangutans, Linnaeus further classified humans as members of the larger ‘Superfamily’ called “Hominoids”, or ‘Apes’. As controversial as Linnaeus’s classification of Humans as a species of Apes was and still is to this day, however, the true paradigm-shifting revolution of Linnaean classification lay further still down what he envisioned as a branching bush-like taxonomic tree. Humans, as apes, belong to the Order of Primates. Linnaeus classified Primates as part of the Class “Mammalia”.[13] Mammals Linnaeus classified as a subcategory of the larger Kingdom “Animalia”. With this, the distinction so long drawn between ‘humans’ and ‘animals’, for all practical intents and purposes, effectively ceased to exist.
Linnaeus also contributed to one other factor of Darwin’s undermining of human exceptionalism by becoming one of the first-ever scientists to publicly question the immutability and fixity of species in his 1751 ‘Plantae Hybridae’, writing, “It is impossible to doubt that there are new species produced by hybrid generation”. In his 1753 ‘Species Plantarum’ [‘The Species of Plants’], Linnaeus referred to species as “temporis filia” [“children of time”], writing in the posthumously published 1792 ‘Praelectiones On Ordines Naturales Plantarum’ [‘Lectures in the Natural Order of Plants’] that “there will arise species that should be referred to the mother’s genus as her daughters”.  After his death, Carolus Linnaeus’s son Carl von Linne wrote of his father that “He believed, no doubt, that species animalium et plantarum and that genera were the works of time.” Indeed, even while he was still alive, in the 1766 12th edition of his ‘Systema Naturae’, Linnaeus himself wrote “Species are the product of time”.[14]  
The most famous proponent of transmutation of the first half of the Eighteenth Century was French naturalist Jean-Baptiste Antoine, Chevalier Lamarck. Lamarck differed from Linnaeus in proposing that speciation occurred not by hybridization between species, but by characteristics inherited generationally, or what Darwin would later come to call his principle of ‘Descent with Modification’, one of the fundamental foundations of his theory of evolution. This is founded upon what might seem to be an extremely simplistic and remarkably readily apparent principle: Offspring do not identically resemble either of their parents.
In a 1796 paper to the French Institute, French zoologist Jean Cuvier proposed that not only could species change, but also they could disappear, a concept Cuvier coined “extinction”.
Combining the time scale of Charles Lyell and the transmutability of species of Lamarck, in his February 1871 book The Descent of Man, Charles Darwin deduced that not only were Humans a species of hominid as Linnaeus had classified them a century earlier, but they were descended, by way of Descent with Modification, from other, extinct species of hominid. Indeed, one such extinct human-related hominid species was discovered during Darwin’s lifetime, and the most recent hominid species from which humans descend was discovered only years after Darwin’s death.
In 1829, Dutch geologist Phillip-Charles Schmerling, the founder of paleontology, discovered a two to three-year-old child’s calvaria [cranium] at Awirs Cave in Engis, Belgium. His find, known as “Engis 2”, included animal bones and stone tools and an upper jaw [maxilla] and upper incisor and lower jaw. After a second discovery of two femora, three right arm bones and two left arm bones by German anatomists and anthropologists Hermann Schaaffhausen and Johann Fuhlrott, the founders of paleoanthropology, at the Kleine Feldhofer Grotte cave in Gesteins, the Neander Valley southwest of Dusseldorf in Westphalia in August 1856, both specimens were jointly named “Neanderthal” [Species “Homo Neanderthalensis”, or Subspecies “Homo Sapiens Neanderthalensis”] by Irish geologist William King in 1864.[15] Then, in 1891, 9 years after Darwin’s death in 1882, Dutch geologist Eugene Francois Dubois discovered a calvaria [skullcap], a tooth and a thighbone, which Dubois dubbed “Java Man”, at Trinil, East Java, Indonesia. After a second discovery of 15 calvariae [crania], 11 lower jaws [mandibles] and many teeth, dubbed “Peking Man” by Swedish archeologist and geologist Johan Gunnar Andersson and Canadian paleoanthropologist Davidson Black at Chou K’out-tien cave in Beijing, China, both specimens were named “Homo Erectus” by German evolutionary taxonomist Ernst Walter Mayer in 1950.[16]
Cuvier had initially formulated his theory of extinction in order to explain the discoveries in 1739 in Big Bone, Boon County, Kentucky of the extinct elephants he called “Mastodons” in 1806[17] and his discoveries in 1808 at Mount Saint Peter near Maastricht, Netherlands of extinct marine reptiles he called ‘Mosasaurus’ [Latin: ‘Lizard of the Maas River’] in 1822[18], as well as the discovery in 1822 by English geologist and paleontologist Gideon Algernon Mantel of an extinct reptile Mantel named “Iguanodon” in 1825[19], a member of what English anatomist and paleontologist Sir Richard Owen named ‘Dinosauria’ [Latin: ‘Fearfully Great Reptiles’] in 1842[20]. The discovery of the extinct hominid ancestors of humans that Darwin predicted in Descent of Man dispelled decisively the delusion that humans held any privileged place outside of or exempted from the evolution and extinction to which every other species is subject.
Thus was the keystone of the scientific revolution that had begun four centuries before with Copernicus finally laid. The analogy to the metaphor of a keystone is especially fitting, since it is the keystone, set last, that gives an archway its strength and stability. As can be seen in Ancient Roman architecture such as the Flavian Amphitheatre Coliseum and the Ancient Roman aqueducts, this then permits still more structures to be built on top of the arch. As the most-tested and most-proven theory in the history of all of scientific thought more than a century and a half after it was first proposed in On the Origin of Species, Charles Darwin’s theory of Descent with Modification through Mutation, Adaptation, Natural Selection and Speciation has extraordinarily remarkable stability, and at the same time allows for other disciplines and fields of scientific study, such as genetics, undreamt of in the mid-Nineteenth Century in which Darwin himself lived. These sciences, in turn, cross-reconfirm Darwin’s original theory by fulfilling the predictions that the theory of evolution makes.
By pushing humans permanently and irreversibly off of whatever high pedestal of privilege we in our delusions of ego placed ourselves upon, Darwin finally brought to full fruition the process that Copernicus began centuries before: That of displacing first our planet and then ourselves from the center of the cosmos. As has been shown here, very nearly each and every discipline and field of science, from anthropology, archaeology, astronomy, biology and cosmology to paleontology, phylogenetics and even physics has had its part to play in replacing the geocentric and self-centered universe of ancient mythologies such as the Judeo-Christian Bible with the more humbling and objective cosmic perspective of Sagan’s Pale Blue Dot. Like an archway assembled stone by stone until the keystone is set, so too was our proverbial gateway out of our dogmatic bubble universe the result of the lifelong study and work of dozens of the most brilliant scientific minds ever to walk this Earth; albeit only a handful of whom have had their names mentioned here; leading us to the mindset whereat the Darwinian worldview was able to see its time come.
The change in governments that we call the American, French and Russian revolutions may very well have taken place on a scale of years, but the concepts enumerated in Jefferson’s Declaration of Independence: “self-evident” truths, “inalienable rights” and the “consent of the governed” did not become the dominant principles forming the foundation of western civilized society overnight. Nor did the paradigm shift in worldview from the geocentric conceptualization of humans as the ‘chosen’ race of the creator god of the cosmos to the humbling view of humans as the product of billions of years of evolution and natural selection and of the planet Earth as Sagan’s Pale Blue Dot occur either with the birth of Charles Darwin in Shrewsbury, Shropshire on February 12, 1809 nor with his publication of his ‘abstract’ on the Origin of Species. The revolution in question, therefore, does not belong to Darwin in and of himself alone as an individual. As his theory proved is true of all of us, Charles Darwin was a part of something much, much, much larger, and longer than the lifetime of one habitually sickly Nineteenth Century English naturalist.
The aforementioned invention of writing permitted the transmission of knowledge across vast distances of space and down through time; and thanks not only to Darwin but to the generations on whose shoulders he was able to stand, we know now what we refused to believe before: That we live in what Sagan called in Chapter 4 of his 1994 book A Pale Blue Dot: “A Universe Not Made For Us”.
