Many people alive today possess some Neanderthal ancestry, according to a landmark scientific study. The finding has surprised many experts, as previous genetic evidence suggested the Neanderthals made little or no contribution to our inheritance. Between 1% and 4% of the Eurasian human genome seems to come from Neanderthals.But the study confirms living humans overwhelmingly trace their ancestry to a small population of Africans who later spread out across the world. The most widely accepted theory of of human origins known as the "out of Africa theory" which states that all ancestors of all living humans originated in Africa some 200,000 years ago. A relatively small group of people then left the continent to populate the rest of the world between 50,000 and 60,000 years ago. Which could be definite proof of people actually originating from Africa.
i believe that our ancestors could have came from Africa for the simple reason that they were hunter's and gathers coming across the land across the land bridges created during the ice age. Not to mention that Neanderthals were the first people which means that they had to have had some influence on the genetics of some people in day. and it just goes to show that they have proof to back it up so it must be a little bit true.
