Darwin, Charles (1809–1882)

Charles Robert Darwin is one of the greatest naturalists who ever lived. He was not only the father of evolution but also a remarkable scientist whose ideas and discoveries about the earth's history resulted in new areas for ongoing research in geology, paleontology, biology, and anthropology. His contributions to science, particularly concerning organic evolution, were possible because he would eventually embrace the vast temporal framework that was being argued for in the emerging disciplines of historical geology and comparative paleontology. Taking both time and change seriously was crucial for the young Darwin, as it resulted in his rejecting the fixity of species and, instead, accepting the mutability of life forms throughout the biological history of this planet.

Darwin's intellectual life evolved from his being a part-time naturalist, interested especially in geology, to his becoming a full-time scientist devoted primarily to biology. He developed a comprehensive orientation in geobiology, and his life was a long series of fortuitous coincidences that collectively propelled him to make major discoveries in the natural sciences. Whether speculating on the formation of coral reefs or reflecting on the similarities between the human species and the apes, Darwin came to see both geological structures and biological forms slowly changing due to the influences of natural forces on them over immense periods of time. His conceptual revolution of organic evolution also challenged the entrenched ideas of Aristotelian philosophy and the dogmatic beliefs of Thomistic theology. Consequently, as a result of Darwin's dynamic worldview, the modern thinker would never again see the earth, life forms, or humankind itself in terms of eternal fixity.

Before Darwin

Aristotle, the father of biology who contributed to embryology and taxonomy, had taught that plant and animal species are eternally fixed within nature. In accordance with his claim that experience reveals reality, it appeared to him that forms of life are static. Likewise, for Aristotle, the same species have always been and always will be on this planet, with none of them ever changing into a different form of life or becoming extinct. He held that, because nature is forever the same, no new species will appear on the earth. However, Aristotle maintained that the human intellect is capable of organizing biological types into a natural hierarchy of ever-increasing complexity and sensitivity; he referred to this order of species as the Great Chain of Being. Although he classified hundreds of organisms and was interested in the embryonic and postnatal development of animals, it never occurred to Aristotle that, through time and change, one species could evolve into a new species. The idea that life forms are eternally fixed dominated Western thought until the scientific writings of Charles Darwin.

Organic evolution was glimpsed in the thoughts of the Roman philosopher Lucretius, geological history was pondered by the Renaissance artist Leonardo da Vinci, and the fact that a species may produce varieties of itself was admitted by the biologist Carolus Linnaeus. Because these three thinkers held ideas that were outside the Aristotelian worldview, however, their concepts on time and change were not taken seriously.
