What was some disadvantages and advantages the Neanderthals has in joining with other communities

Interbreeding with Neanderthals gave some of our ancestors distinctive skin and hair, but also left behind a legacy of disease within our DNA.

Non-African people today carry Neanderthal DNA in their genetic make-up that is associated with changes in hair and skin, but also with diseases such as diabetes, Crohn’s and even conditions such as chronic depression and addictive behaviour.

Modern humans began to leave Africa around 60,000 years ago, encountering Neanderthals as they moved into Eurasia. Studies in the past few years show that modern humans interbred with Neanderthals, albeit rarely.

Two new studies released this week revealed part of the legacy of these interactions, concluding that the genome, or complete genetic map, of a modern non-African person contains about two per cent Neanderthal DNA.

‘These findings provide yet another twist to the hotly-debated Neanderthal interbreeding story,’ said Museum human origins expert Prof Chris Stringer.

Pros and cons

The studies compared the genome of a Neanderthal with those of hundreds of modern humans, both from Eurasia, where our ancestors met Neanderthals, and from sub-Saharan Africa, where there would have been no interbreeding.

The Neanderthal genome comes from the toe bone of a female individual, and the modern human information comes from data banks of genetic codes.

The researchers found Neanderthal DNA in regions of the human genome associated with skin and hair, suggesting early humans leaving Africa benefited from interbreeding, perhaps giving them thicker, straighter hair and skin that helped them cope better with the colder Eurasian climate.

However, Neanderthal DNA was also found in parts of the human genome associated with diseases such as diabetes, lupus, biliary cirrhosis and Crohn’s disease, which causes inflammation of the gut.
