NATURE : MYSTERY HUMANS SPICED UP ANCIENTS SEX LIVES
"All modern humans whose ancestry originates outside of Africa owe about 2% of their genome to Neanderthals. Certain populations living in Oceania, such as Papua New Guineans and Australian Aboriginals, share about 4% of their DNA with Denisovans, members of a group named after a cave in the Altai Mountains in Siberia, Russia, where they were discovered. The cave contains remains deposited between 30,000 and 50,000 years ago."
WHAT THIS MEANS IS THAT THERE IS SCIENTIFIC PROOF THAT THERE WERE DIFFERENT BREEDS (my word) OF HUMAN ANCESTORS LIVING AT THE SAME TIME AND THAT THEY INTERBRED.
I'm thinking of my dog when I use this word. I think it may be useful to image, since we all know that sometimes a maltese and a poodle, and other dogs that are not similar in look or size, do breed, or are bred. In this case, some lonely Neanderthals found the Denisovans all right!
So if you think you have an uncle who is more than 4% Neanderthal...

DNA GENEALOGY BRINGS US TO THE SCIENCE OF DNA
DNA GENEALOGY is so fascinating. It seems that every day the scientists are able to lead us to our genetic and ethnic heritage, though I've met more than one person who was surprised. If we're going to trust that science, we're probably going to want to know more about it, and what information about HUMANITY AS A WHOLE IS BEING REVEALED.
IBTIMES : OLDEST DNA 400,000 YEARS OLD
"The bone, found in a cave in northern Spain known as the “Pit of Bones,” is the oldest human mitochondrial material ever sequenced. But rather than reveling in their discovery, scientists are getting frustrated.....
Svante Paabo, the director of the Max Planck Institute for Evolutionary Antrhopolgy in Leipzig, Germany, added that the results “show that we can now study DNA from human ancestors that are hundreds of thousands of years old," adding that the discovery was “tremendously exciting."
The reason scientists are flustered? Researchers were expecting to uncover DNA from a Neanderthal, which once inhabited Europe and parts of Asia. But the DNA actually turned out to be very similar to a different kind of prehistoric people, the Denisovans, who lived thousands of miles away in what is now Siberia. First discovered in 2010, the Denisovans were a genetically distinct group of people who are known only by a pinkie bone and a tooth..."
