heredity; but he cannot free himself from the
thralldom of environmental influences or from the
inexorable limitations of his ancestral heritage.
In some respects, indeed, man is far more ham-
pered when he attempts to apply the laws of
heredity to his own race than he is in making
application of the same laws to the basis of tran-
sient animals under domestication. The necessi-
ties of the social organism that he has built up
place limitations on his freedom of selection in
the mating of individuals and even sharper restric-

parents of future generations.
