Last evidence

Neanderthal interbreeding
The Neanderthal interbreeding article is based on a scientifical study. The result from the article suggests that the human being shares up to 4% of it’s genome with Neanderthals. The study supports the theory that living beings for the most part trace their ancestry to a small population of Africans who later spread out across the world-‘’Out of Afric’’. There has therefore been an interbreeding between neantherthals and moderna humans in the past.The results show that the genomes of non-Africans (from Europe, China and New Guinea) are closer to the Neanderthal sequence than are those from Africa. The most likely explanation, say the researchers, is that there was limited mating, or "gene flow", between Neanderthals and the ancestors of present-day Eurasians.
This must have taken place just as people were leaving Africa, while they were still part of one pioneering population. Another version allows for a degree of assimilation, or absorption, of other human types into the Homo sapiens gene pool. The latest research supports the Out of
Africa theory, but it falsifies the most conservative version of events


Homo floriensis (hobbit)
A few years ago, remains of a different type of homonoid was found on the island Flores, near Indonesia: Homo floriensis. It was suggested that this homonoid had evolved from Homo Erectus that had also been found in Indonesia at this time (about 1 million BP). However, the homo floriensis has only been found on that specific island and the island can only be reached through traveling on the water.

the founding of homo floriensis supports the multi regional theory in a way, since homo floriensis were found 12.000 years ago it suggests that homo erectus never actually were extinct.


Home Denisovan
The Homo Denisovan was interbreeding with the other human species about 45000 years ago, when the Neanderthal and the Homo Sapiens Modern were walking our planet. What this suggests, is that the Denisovans were interbreading with the Homo Sapiens Modern and the Neanderthal, which would support the theory ”Multi Regional”, since the theory sais that the different species around the world were interbreading with eachothers and at last evolved into the Homo Sapiens Modern.
