In 1794, Erasmus Darwin, an English physician, published “Zoonomia; or the Laws of Organic Life” which postulated early ideas relating to the theory of evolution.

His theories of biological evolution by means of natural selection, although criticised by the church, were handed down from father to son and to grandson; but it was left to his grandson, Charles, to prove biological evolution.

In 1859, his grandson Charles published his theory of evolution in his book “On the Origin of Species.”
