Neanderthals gave us disease genes
Researchers have discovered evidence that many modern afflictions, such as addiction to smoking, depression, and diabetes are linked to early humans interbreeding with Neanderthals hundreds of thousands of years ago.
The research by Harvard Medical School suggests that our species also acquired neanderthal genes that helped us adapt to the colder climates of Europe and Asia.
