Neanderthals were great hunters but poor artists.
According to a study done by UC Davis psychology professor Richard Coss, Neanderthals used basic spear hunting techniques to capture tame prey.
Meanwhile, Homo Sapiens developed the ability to throw spears as a result of chasing more elusive game in the open grasslands of Africa.
Homo Sapiens were also careful planners, sharpening their hand-eye coordination by drawing out hunting scenes on cave walls.
Such artistry not only made modern humans better visualizers and hunters, but it also helped them develop smarter brains.
Historian and author of Sapiens: A Brief History of Humankind Yuval Noah Harari also argued that while Neanderthals might have had larger brains and finer tools than their fellow Homo Sapiens, they lacked the cognitive abilities for language.
Homo Sapiens developed rounder skulls and bigger parietal cortexes that allowed them not only to translate visual images but share stories through word of mouth.
