Asa Gray is considered the most important American botanist of the 19th century. His Darwiniana was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator.

Theistic evolution, alternatively called evolutionary creationism, is a view that God acts and creates through laws of nature. Here, God is taken as the primary cause while natural causes are secondary, positing that the concept of God and religious beliefs are compatible with the findings of modern science, including evolution. Theistic evolution is not in itself a scientific theory, but includes a range of views about how science relates to religious beliefs and the extent to which God intervenes. It rejects the strict creationist doctrines of special creation, but can include beliefs such as creation of the human soul. Modern theistic evolution accepts the general scientific consensus on the age of the Earth, the age of the universe, the Big Bang, the origin of the Solar System, the origin of life, and evolution.
In the 19th century, geology and paleontology were still connected to Old Earth creationism. The above depicts a brutal world of deep time, existing before Adam and Eve, from Thomas Hawkins' book on plesiosaurs. Artist: John Martin, 1840
