Human lack of genetic diversity

    "Unlike our close genetic relatives - chimps - all humans have virtually identical DNA. In fact, one group of chimps can have more genetic diversity than all of the six billion humans alive today."

    When humans faced extinction
    By Dr David Whitehouse 6/9/2003

    What are they talking about when they reference chimps genetic diversity vs humans? Differences in the non protein coding portions of the chromosomes?

    Would have to see the paper - does the author explain his calculations?

    The massive eruption of Mt. Toba on the island of Sumatra about 71,000 years ago is thought to be the cause of a genetic bottleneck resulting in a founder effect for a small group of surviving humans. However, I don't know how well accepted this hypothesis is. It seems to require that, to be "founders", the surviving humans were a geographically concentrated (and isolated) interbreeding population.
