Neanderthal brains reached full size between the ages of 6 and 8 years and that they were about 10 percent larger than the brains of modern humans.
«It's been proposed that Neanderthals depended on visual - spatial abilities and toolmaking, for survival, more so than on the social affiliation and group activities that typify the success of modern humans — and that
Neanderthal brains evolved to preferentially support these visuospatial functions,» Berman explained.

The team found that ARHGAP11B was also present in

brains.
