    Default A Repository of Useful Links/URLs Under the Subject of Evolution


    Hi mods and fellow istoryans,

    I just wanna make a thread for all related topics, videos, images that serve as evidence for Evolution. It would be nice if you guys could also share your materials.

    So for now, here's mine, and there's more to come.

    Understanding Genetics: Human Health and the Genome
    Scientists Use DNA to Find Our Newest Relatives, the Denisovans

    Gone but not Forgotten, Their DNA Lives on in Melanesians
    portrait_barry.jpg
    by Dr. Barry Starr, Stanford University

    January 6, 2011

    Scientists found humankind's newest relative, the Denisovan, by looking at the DNA of a thirty thousand year old fossilized finger from the Denisova Cave in Siberia. This is the first time DNA has been used to discover a new hominid. As scientists get better and better at looking at ancient DNA, they may find additional relatives this way too.


    Our newest relative was
    identified from the DNA of
    a fossilized pinky found
    in this cave.
    Finding new hominids by looking at DNA has another advantage--scientists can learn whether any of that DNA lives on in modern humans. Scientists had already shown that 1-2% of non-African DNA might have come from Neanderthals. Now it looks like 4-5% of Melanesian DNA may have come from Denisovans.

    Apparently before humans wiped out all of their competition, they had children with some of them first. This legacy lives on in modern human DNA.

    Looking at the DNA of related hominids is also changing how scientists look at and think about human prehistory. Before scientists could sequence DNA, there were two main theories to explain the fossil evidence.

    The Out of Africa theory held that all humans evolved in Africa and then spread out and destroyed any hominid species they found. The multiregional hypothesis proposed that each ethnic group of humans evolved separately.

    Looking at the DNA of modern humans pretty much eliminated the multiregional hypothesis. Everyone's DNA is way too similar to have evolved separately.

    But it does look like the hominids from different regions of the world may have contributed their DNA to specific human groups. This isn't quite multiregional hypothesis but it does have some of the same consequences. Different groups of humans have small amounts of DNA that evolved in a completely different context.

    It will be interesting to see if this "other" DNA contributes to any special traits of certain populations. Or if they are really just markers from human's distant past that no longer do much of anything.

    Being able to look at DNA promises to shake up this field like it has nearly every other field in biology. New results with human and, hopefully, hominid DNA are going to be coming in fast and furious as sequencing gets cheaper and cheaper. This won't only help everyone live longer and healthier lives, but it will also help scientists learn about humankind's past and how all humans are related in ways they never would have thought possible.
