Nothing in Biology Makes Sense Except in The Light of Evolution - Overview

Overview

Dobzhansky starts with a reductio ad absurdum of the alleged geocentrism of Shaikh Abdul Aziz bin Baz, the then Grand Mufti of Saudi Arabia, who believes the Sun revolves around the Earth because of scripture. Dobzhansky asserts his own belief that scripture and science do not contradict each other. He criticizes creationists and argue the imply that God is deceitful and asserts that this is blasphemous.

Dobzhansky then goes on to describe the diversity of life on Earth, arguing that the diversity of species cannot be best explained by a creation myth because of the ecological interactions between them. He uses examples of evidence for evolution: the genetic sequence of cytochrome C to show evidence for common descent (citing the work of Emanuel Margoliash & Walter M. Fitch); embryology; and his own work on fruit flies in Hawaii. Dobzhansky concludes that scripture and science are two different things: "It is a blunder to mistake the Holy Scriptures for elementary textbooks of astronomy, geology, biology, and anthropology".
