Both of these branches of evolutionary science, are, in my opinion, in the closest causal connection; this arises from the reciprocal action of … Read more

Heredity is to-day the central problem of biology. This problem may be approached from many sides – that of the breeder, the experimenter, the statistician, the physiologist, the embryologist, the cytologist – but the mechanism of heredity can be studied best by the investigation of the germ cells and their development.

From the point of

From the point of view of the pure morphologist the recapitulation theory is an instrument of research enabling him to reconstruct probable lines of descent; from the standpoint of the student of development and heredity the fact of recapitulation is a difficult problem whose solution would perhaps give the key to a true understanding of … Read more

We should in this way look on the nature of … Read more
