According to research the remains of Neanderthal DNA would be associated with genes involved in diabetes, lupus, and even smoking.

Two different studies published in scientific journals Nature and Science confirms the amount of Neanderthal genes that run through the veins of modern humans.
According to investigations neandertal residues would be associated DNA genes involved in diabetes, lupus, Crohn's disease and even smoking.
In addition, the investigations suggest that the Neanderthal genome may have helped modern humans to adapt to non-African environments.
Just four years ago surprised the world anthropology pointing that between 1 to 4% of the human genome (2% of their genes) are from the Neanderthal man, a species which appeared about 400,000 years ago and became extinct 30,000.
