R_2_02 — Convergent Evolution and the Aquatic Ape Hypothesis

Convergent evolution — the independent development of similar features in unrelated lineages — is one of biology's most profound patterns. Eyes evolved independently at least 40-65 times (Fernald 2006). Echolocation evol

R_2_01 — Human Brain Evolution and the Cognitive Revolution

The human brain tripled in size over 3 million years — from ~400 cm³ (Australopithecus) to ~1,400 cm³ (modern Homo sapiens). This is the most dramatic encephalization in the history of life, and NO consensus exists on wh
