Interbreeding with Neanderthals boosted modern human immune system

A new study, published in Science, says that humans interbreeding with Neanderthals could have boosted the modern human immune system.

Modern humans, Neanderthals and Denisovans all share a common ancestor in Africa. These populations split up about 400,000 years ago in distinct groups. One went northwest, giving rise to the Neanderthal lineage, another one went northeast, forming the root of the Denisovan lineage, and the third one stayed in Africa. For a while, at least. Several hundreds of thousands of years later, the African population expanded into Eurasia, meeting their evolutionary cousins.

In his book - Secrets Of The Underground Door To An Ancient World - he claims the fact that so many have survived after 12,000 years shows that the original tunnel network must have been enormous.
