Book review: Andrei P. Kozlov “Evolution by tumor neofunctionalization: the role of tumors in the origin of new cell types, tissues and organs”. Amsterdam, Boston, Heidelberg, London, New York, Oxford, Paris, San Diego, San Francisco, Singapore, Sydney, Tokyo: Academic Press/Elsevier, 2014. 248 p. ISBN: 978-0-12-800165-3

A review of the book by Professor Andrei P. Kozlov is presented. It is noted that the neofunctionalization of tumors is definitely an unconventional idea put forward by a decidedly unconventional thinker. The book combines both well-known evolutionary and ecological concepts, as well as little-known theories, and thoughtful consideration is given to each of them. And although many scientists will undoubtedly disagree with its main conclusions (it remains to be seen whether examples such as the goldfish cap are the exception or the rule), the book in many ways encourages reflection and provides ample ground for experimentation, thereby stimulating the further development of scientific thought. “Evolution by neofunctionalization of tumors” by A.P. Kozlov will be an important reading for anyone studying evolution and genomics, especially for the ideological leaders of Darwinian medicine.
