Peter J. Bowler FBA (born 8 October 1944)[1] is a historian of biology who has written extensively on the history of evolutionary thought, the history of the environmental sciences, and on the history of genetics. His 1984 book, Evolution: The History of an Idea is a standard textbook on the history of evolution; a 25th anniversary edition came in 2009. His 1983 book The Eclipse of Darwinism: Anti-Darwinian Evolution Theories in the Decades Around 1900 describes (in a phrase of Julian Huxley's) the scientific predominance of other evolutionary theories which led many to minimise the significance of natural selection, in the first part of the twentieth century before genetics was reconciled with natural selection in the modern synthesis.
