Neanderthals were great hunters but poor artists.
According to a study done by professor Richard Coss, their inability to draw could’ve been due to the fact that they didn’t have to plan as hard as Homo Sapiens to hunt down prey in their native Eurasia.
Homo Sapiens, on the other hand, chased hard to get game in the open grasslands of Africa. They developed superior hand-eye coordination as a result of drawing out their prey on cave walls. Such artistry not only made them better visualizers and hunters, it also helped them develop smarter brains.
Survival of the fittest
Historian and author of Sapiens: A Brief History of Humankind Yuval Noah Harari also argued that while Neanderthals might have had larger brains than and an even superior tools to fellow Homo Sapiens, they lacked communication and shared stories, concepts that emerged from rounder skulls.
