The first half of the book explores Ernst Haeckel's biogenetic law (recapitulation)—the discredited idea that embryonic developmental stages replay the evolutionary transitions of adult forms of an organism's past descendants—and how this idea influenced thinking in biology, theology, and psychology.

Evolutionary thought, the recognition that species change over time and the perceived understanding of how such processes work, has roots in antiquity.
