Denisovan+Neanderthal+Sapien

Recent findings in Siberia by Russian archeologists base a conclusion on a 50,000 year old finger.

The finger was found near the site of other recent findings of Denisovan culture which may have existed there over 100,000-400,000 years ago. The finding of the DNA from the finger indicates the make up of the specimen has a mix breeding of Neanderthal, Denisovan and Homo Sapien background. This finding is from one bone, one person.

This is regarded as the first indication that the three races had interbred over time according to finding that the DNA was shared and passed on  into Homo Sapiens and was located in Siberia.

This has allowed for more depth exploration on the subject matter. Other scientists examine closely mixed tracings of DNA branches, dubbed "ghosts" with Neanderthal and others back into early African migrations. It is indicative that other branches may have been interbreeding even in the early African migrations and those need to be fleshed out. There may have been different populations long ago in Africa that scientists are not yet aware of. Those may have contributed to the DNA pool, but are yet to be confirmed.
