selection thesis-was given the name of neo-Darwinism. Therefore,
Ernst Mayr and the other founders of the theory (Theodosius
Dobzhansky and Julian Huxley) began being referred to as neo-
Darwinists. Ernst Mayr was one of the most significant adherents
of the theory of evolution in the 20th century. He based his

impossibility of this: The occurrence of genetic monstrosities
by mutation . . . is well substantiated, but they are such
evident freaks that these monsters can be designated only as
‘hopeless.' They are so utterly unbalanced that they would not
have the slightest chance of escaping elimination through
stabilizing selection . . . the more drastically a mutation
