Men All Have One Common Ancestor

h52FC6105Looks like we’re all related whether you like it or not. That’s good news: I need help painting my house next weekend.

Vi LA Times:

In work made public today in the journal Science, the team of prominent biologists corroborates the idea that modern humanity originated around 200,000 to 300,000 years ago, rather than a million years earlier, as other experts have theorized.

“It suggests we really are an extremely recent species on this planet,” said Yale University biologist Robert L. Dorit, who led the group. “We are definitely rookies . . . noisy, but new.”

The new research also provides additional evidence that modern humans–despite their apparent racial and ethnic differences–all share the same basic genetic makeup. In one section of the chromosome that makes a person male, men around the world are virtually identical, the scientists discovered.

For their analysis, they sequenced a portion of the male sex chromosome that apparently changes quite slowly over the eons. To ensure that their sample would encompass the range of human geographic diversity, they used chromosomes from 38 men chosen from every continent. They discovered virtually no differences, despite the fact that genetic mutations usually occur at a predictable rate.

“Originally we were terribly surprised by the lack of variation,” said Harvard University biologist Walter Gilbert, a Nobel laureate who worked on the study. “We realized very early that meant a recent common male ancestor.”

Keep reading, cuz.

    what’s the harm of little lying blaspheming IDI*TS!

    how we won the James Randi Million Dollar Paranormal Prize

    and his name was Adam

    Madame, I’m Adam!

    I thought they already knew this? Mitochondrial Eve, and all that?

    Did modern humans descend form an “Adam”?
    or were there already many “Adams” around
    all with same genetics
    we are not capable of knowing this using today’s technological tools
    but we do know that:
    125,000 years ago the Earth’s temperature rose to & above modern levels
    this lasted for about 15K years & then a new 100,000 year ice age began
    at that same time 125K years ago
    at least 3 different species of humans existed
    only modern humans survived the last ice age
    the other species had that had lived during the preceding ice age did not
    beyond that, it’s all conjecture

      Saying “we’re a very recent species” sounds a bit premature based on this data.
      We recently learned that genetic bits of our extinct relatives live on in our dna. There should be much more to learn about our prehistory.

        I think it’s entirely possible that our ancestors (or perhaps even lines that died off) had complex societies before the ice age…that’s a lot of time to be sitting around twiddling our opposable thumbs.

        I don’t necessarily mean Atlantis and nuclear technology and space flight and la-dee-da, etc, but as you say, there is much to learn…

          I actually have a gut instinct that our story has been mostly lost, and wouldn’t be surprised if advanced tech was part of that distant past. But speculating further without evidence leads to all kinds of mumbo jumbo. 🙂 The truth is out there somewhere…

    ALL of us?
    That mo’ fo’ sure had some stamina.

    It’s all conjecture. They have no hard proof.
