Why Neanderthals had protruding faces …

Scientists may have finally uncovered why our extinct relatives the Neanderthals had protruding faces and giant nostrils. Digital reconstructions of Neanderthal skulls reveal the features helped them to breathe in more air while they were running and hunting. The species’ jutting craniums may have also helped them to adapt to the cold when they migrated to Eurasia from Africa around 500,000 years ago. Previously, researchers have suggested Neanderthals evolved their strangely shaped skulls because they made heavy use of their large front teeth, perhaps even employing them as tools. But the new study shows it gave Neanderthals a huge internal nasal passage that helped them blow more air in and out of their lungs more quickly … [read this article on Daily Mail]
