Did natural selection or genetic drift produce the cranial diversification of neotropical monkeys?

The American naturalist - 1 Mar 2004

Marroig Gabriel, Cheverud James M

Abstract excerpt

A central controversy among biologists is the relative importance of natural selection and genetic drift as creative forces shaping biological diversification (Fisher 1930; Wright 1931). Historically, this controversy has been an effective engine powering several evolutionary research programs during the last century (Provine 1989). While all biologists agree that both processes operate in nature to produce...
