No question in biology has been discussed with more animation than that of the transmission by heredity of acquired defects.

The effects produced by his criticisms have been undoubtedly beneficial in removing from certain ideas of heredity their crudeness. The older notions of heredity were much more vague and at the same time more sweeping than those held by modern biologists.
