Abstract

Laland et al. suggest that as a specific evolutionary force niche construction has entailed the encephalization of the brain. While not denying rapid co-evolution of brain traits and abilities with niches and cultures, I argue that encephalization reflects a classical genetic buffer systemallowing rapid evolutionary adaptation independent of the nature of the selective pressure.
