In the realm of biology, for example, Charles Darwin (1809–1882) laid out a complex argument that all life was in constant change, that an endless and competitive struggle for survival over millions of years constantly generated new species of plants and animals, while casting others into extinction.
To prove this point, Charles Darwin examined the island of Galapagos, specifically the finches of said island. According to a documentary that I saw for an anthropology class, over the course of many years, Darwin returned to the island and noted the changes in the plumes and beaks of the finches as generations of them went by; from this, he proved his theory of evolution. This section of the chapter mentions 3 names in particular of prominent people who disproved, in one way or another, the ideology behind Christianity on a biological level. Aside from these 3, who all influenced this challenge to Christian ideology? Were there others who may have influenced any of these 3, such as someone whose work individually would not propose much of an opposition, but who drove forth this level of thinking nonetheless?
