    DNA results are in: Early humans and Neanderthals made babies together

    The following represents further research confirming earlier studies defining the relationship between homo sapiens, and other homo subspecies. The most important conclusion in this genetic research is that it confirms the modern evolution of homo sapiens, and mixing with other homo relatives as we migrated out of Africa. The Neanderthal and Denisovans DNA is missing from Africans.

    DNA results are in: Early humans and Neanderthals made babies together

    (CNN)Neanderthals may not have been as lucky as our human ancestors in the long run, but that doesn't mean the two subspecies didn't get lucky.

    Scientists have discovered that Homo sapiens -- that's us -- made more babies with archaic humanlike species than initially thought. That sexual history has left a mark on the human genome, possibly influencing our immune systems and metabolism, according to a new study published in the journal of Science.

    Scientists analyzed the genetic information of more than 1,500 people from all around the world and determined that ancestors of modern humans interbred with Neanderthals and Denisovans.

    They learned that some Asians, Europeans and even the Melanesians of Papua New Guinea had Neanderthal and Denisovan ancestry.

    Mystery surrounds the Denisovans, which were related to Neanderthals but genetically different, in much the same way Neanderthals were distinct from modern humans. In 2008, fossil remains of Denisovans were discovered in a cave in Siberia.

    The discovery of traces of Denisovan DNA in the people of Melanesia is significant because the Pacific Islanders live thousands of miles away from the Siberian region that Denisovans are believed to have existed.

    "It is still not exactly clear when and where Melanesian ancestors crossed paths with Denisovans, but our best guess is somewhere in mainland Southeast Asia," University of Washington evolutionary geneticist Joshua Akey, who helped lead the study, told CNN.
    This is a likely scenario based on the low levels of Denisovan ancestry found in some South Asian populations.

    The study confirms early theories that our human ancestors interbred with other hominins after they left Africa more than 50,000 years ago.

    But Jorge is my beloved Christian brother! You put me in the same category with Tazzy and Jimmy, and you didn't provide a trigger warning!

    Considering that tiny amounts of Neanderthal DNA can be found in some modern populations this news seems anti-climatic.

    Impact on the Caucasian and Oriental human genome is the important issue, not the amount. The Neanderthal DNA is already 95%+ or more common to the human genome. This research documents better the relationship and the impact on human evolution out of Africa. Much of the Caucasian and Oriental population owes its adaption to some diseases, and northern and mesic climates to the contribution of Neanderthal DNA. There is evidence that we would not have those red headed freckled, and blond beauties without Neanderthal DNA.

    It is apparent when comparing the other primates living today it only takes a relatively small amount of DNA change to make a radical difference in the evolution of species.

    Where is that smiley by the fireplace? Would have gone great here as a reply.
