The neanderthal man became extinct 40,000 years ago

45,000 years ago the european continent was mainly inhabited by the neanderthals, and a few individuals of the “new” human specie originated in Africa some 200,000 years ago. 5,000 years later, the neanderthals were completely extinct, and the new human specie was widespread through the whole continent. In this short period that both species lived together, there was a cultural and genetic transmission.

And how neanderthal are you?

Scientific have found that Eurasian people share between 1-4% of our DNA with neanderthals.The genes we share with them are especially involved in creating keratin filaments but also have relation with the immune system. These genes were kept in our genome because they were useful in our evolution and in our adaptation to different environments. However, there are some genes that affect the risk of several diseases, including lupus, biliary cirrhosis, Crohn’s disease, and type 2 diabetes.

Neanderthal sequences are typically inherited in large batches, since they were imported into the modern human genome relatively recently and have not had time to break apart.
