Have Humans Come Close To Extinction?

Posted by timothy on from the closer-than-today-that-is dept.

waytoomuchcoffee writes "According to a new study, our virtually identical DNA indicates humans were close to extinction about 70,000 years ago. Another take on the same study tells how being lactose intolerant in adulthood was normal, and being able to digest lactose became a survival advantage after dairy farming was invented."

    being able to digest lactose became a survival advantage after dairy farming was invented.

    So at some point some humans said:

    "Hey lets invent dairy farming!"
    "Hmm, but we're all lactose intolerant..."
    "What the heck, if we take this crap every day we'll eventually mutate and some generations down they will be thanking us."

    Nice long-term thinking there, thanks!
