4 Darwin suggested that through reproduction, natural selection encourages organisms to change and adapt to their environments. Successful evolutionary adaptations ensure the survival of a species.
5 In a famous 1860 court debate with Bishop Samuel Wilberforce, English Biologist Thomas H. Huxley defended evolution:
6 His opponents enjoyed it when Bishop “Soapy Sam” Wilberforce asked him, “Are you descended from an ape, Mr. Huxley, from your mother’s or your father’s side?” Huxley’s reply put Wilberforce’s “science” into perspective. If such a question were to be put to me, Huxley replied, “would I rather have a miserable ape for a grandfather or a man highly endowed by nature and possessed of great influence and yet who employs these faculties and that influence for the mere purpose of introducing ridicule into a grave scientific discussion, I unhesitatingly affirm my preference for the ape.”
