About this book

Essays Upon Heredity and Kindred Biological Problems brings essays together in a single volume, as the author's preface explains. A biological argument distinguishes the breaking up of a body as a preparation for reproduction from its breaking up as a consequence. A description of embryonic development says that all layers of the mother's body persist while the offspring develop, including the outer layer.

The argument about variability questions whether greater variability in males of many animal species permits the conclusion that variability comes from the male parent. The discussion acknowledges that in many species males have led processes of transformation while females have followed. A criticism of molecular affinity says that, even if the affinity exists, its origin and control remain unintelligible if it arose from differentiation of the complete colony.
