Later hominin evolution shows that brain size increases while facial size decreases. Examples of this trend include Homo erectus and Homo neanderthalensis, both of which had larger brain sizes and smaller facial sizes than their earlier hominin ancestors. This trend has been explained by a shift towards more complex social structures and tool use, which favored individuals with larger brains and more precise motor control while reducing the demands for a large chewing apparatus.
