Link 2: Complex cognition shaped the Stone Age hand axe -- ScienceDaily
Emory Health Sciences. The ability to make a Lower Paleolithic hand axe depends on complex cognitive control by the prefrontal cortex, including the 'central executive' function of working memory, a new study finds. The results knock another chip off theories that Stone Age hand axes are simple tools that don't involve higher-order executive function of the brain...
