Gerald Allan Kerkut (or G. A. Kerkut) (19 August 1927 – 6 March 2004) was a noted British zoologist and physiologist.


He attended the University of Cambridge from 1945 to 1952 and earned a doctorate in zoology. He went on to establish the Department of Physiology and Biochemistry at University of Southampton where he remained throughout his career. He became Professor of Physiology and Biochemistry in 1966 and went on to become the Dean of Science, Chairman of the School of Biochemical and Physiological Sciences and Head of the Department of Neurophysiology.


Kerkut's book The Implications of Evolution pointed out some existing unsolved problems and points of concern for evolutionary studies. He referred to seven evolutionary assumptions which he felt lacked sufficient evidentiary support.[1][2][3] Biologist Theodosius Dobzhansky took issue with Kerkut's statements about evolution.[4] The book has been criticized for inadequately describing the fossil evidence for evolution.[5]

Botanist Elwood B. Ehrle in a review has noted:

[Kerkut] apparently makes the mistake of assuming that the case for evolution rests on the documentation of a monophyletic development of the animal kingdom-indeed, of all life. Even if it should be conceded that polyphylesis is the rule rather than the exception, the fact of evolution remains in crystalline clarity.[6]

Creationists have taken Kerkut's points as evidence against evolution and interpreted them to support their own claims.[7] In his book, Kerkut distinguished between the Special Theory of Evolution (often referred to as microevolution) and what he termed the General Theory of Evolution (often referred to as macroevolution, but also including abiogenesis).[8]
