DNA inherited from Neanderthals may impact human nose shape, study finds | Science & Tech News
admin
The shape of modern human noses may be partly determined by genetic material inherited from Neanderthals, according to a new study. Neanderthals were an ancient species who lived in Eurasia until their extinction about 40,000 years ago. But scientists believe they interbred with homo sapiens – meaning some of their DNA remains in modern-day humans.…
