Evolutionary developmental biology
"In a series of remarkable books that established the synthetic theory of evolution, Gavin de Beer's Embryology and evolution was the first and the shortest (1930; expanded and retitled Embryos and ancestors, 1940; 3rd ed 1958). In 116 pages de Beer brought embryology into the developing orthodoxy... for more than forty years, this book has dominated English thought on the relationship between ontogeny and phylogeny".
