Dating Between Modern Humans and Neandertals


Max Planck Institute scientists predicted when Neandertals and Europeans now shared ancestors the last time. They did that to find out why Neanderthals are related a lot to people outside of Africa. The research which they did shows a “historical context for the interbreeding”. It tells us that it happened when us humans brought Upper Paleolithic knowledge found Neanderthals while they were going out of Africa.

“When the Neanderthal genome was sequenced in 2010” it showed that citizens which aren’t in Africa, have a little bit more genetic similarities with Neanderthals. The fact that humans mixed with Neanderthals when they went out of Africa explains this thought. 

Dr. Sriram Sankararaman calculated the extent of DNA parts in the genomes of the Europeans, which are very alike to Neanderthals. “Since recombination between chromosomes when egg and sperm cells are formed reduces the size of such pieces in each generation” the Neanderthal pieces will become smaller the longer they spend in the genomes of now living people.
The team came to a conclsion, they think that humans and Neanderthals traded genes at about 37000 to 86000 years ago, this shows that Neanderthals had kids with the ancestor of now living people out of Africa   

I choose this event because it stood out to me. I like anything that has to do with history, ancestor etc. I quoted some parts because I really liked how they said the statement. I would really like to see one of my ancestors, how they look like compared to me ad my family.
