london - Scientists have solved the riddle why Neanderthals have such a big nose.
New scientific research shows that the distant cousin of the human being desperately needed his huge gamble. Neanderthals ran around all day and were often on the hunt. They quickly burned 4500 calories per day, which we can now easily use with 2500. And more food means more burning, which requires extra oxygen.
The big nose was needed to warm up the often icy air when sucking up and make it more humid before it got into the lungs. In fact, they had a more efficient nose than us, writes the site PhysOrg.
