The Biological Problem of To-day: Preformation Or Epigenesis?
Oscar Hertwig and P. Chalmers (Peter Chalmers), Sir Mitchell
Is a living creature folded up complete inside the egg, or does it truly build itself from scratch? Oscar Hertwig weighs this ancient question with the new evidence of cells and development, laying groundwork for a theory of how organisms grow. A sharp, thoughtful entry in the great debate over life's beginnings. Puzzle over how a single cell becomes a whole animal.
Every copy includes a printable PDF edition, a beautifully typeset book you can print, mark up in the margins, and keep on your shelf. Yours the moment you own it.
