Question

Quizplus · Accepted Answer

Paedomorphosis refers to the retention of juvenile traits in adult organisms. Progenesis and neoteny are the two types of paedomorphosis - progenesis is when an organism reaches sexual maturity at an earlier developmental stage than its ancestors, while neoteny is when an organism retains juvenile traits into adulthood. Hypermorphosis and acceleration are not forms of paedomorphosis - hypermorphosis is the extension of growth beyond the ancestral norm, and acceleration is an increase in the rate of development.
