That’s the point. Darwood couldn’t find any evidence to back up his lame attempt to completely reinterpret the entire history of biological. He started with the conclusion, couldn’t find any evidence to back it up, and published his conclusion anyway—and the “unfulfilled” atheists and agnostics of his day drank it up like Kool-Aid on a hot summer day.
What history of biology? The Bible? That’s your scientific basis? Fine for RELIGION. Not Science.
