Life history traits affect the life table of an organism. A species’ life history is genetically determined and shaped by the environment and natural selection.

It introduces the recapitulation theory, which posits that early developmental stages mirror ancestral forms, despite variations among species. The page notes that while embryos exhibit analogous features like limb bud formation, many are lost or altered later.

A biochemist might examine, for instance, the influence of social and ecological conditions on the release of certain neurotransmitters and hormones, and the effects of such releases on behaviour, e.g.
