One was prerequisiteism, the belief that every species has essential characteristics that are unalterable, a concept which had developed from medieval Aristotelean metaphysics, and that fit well with born(p) theology. The other one was the tuition of the vernal anti-Aristotelian approach to modern science: as the prescience progressed, evolutionary cosmology and the mechanical philosophy spread from the strong-arm sciences to natural history.
Naturalists began to focus on the variability of species; the emergence of fossilology with the concept of extinction further undermined the static view of nature. In the early 19th century, Jean-Baptiste Lamarck proposed his theory of the transmutation of species, the first fully formed theory of evolution.
In 1858, Charles Darwin and Alfred Russel Wallace published a new evolutionary theory that was explained in detail in Darwins On the Origin of Species (1859). Unlike Lamarck, Darwin proposed common descent and a bifurcate tree of life, meaning that two very different species could endure identical ancestry. The theory was based on the idea of natural selection, and it synthesized a broad range of evidence from animal husbandry, biogeography, geology, morphology, and...If you command to get a full essay, order it on our website: Orderessay
