Was Human Evolution Caused by Climate Change?

Via ScienceDaily:

According to a paper published in Science, models of how animal and plant distributions are affected by climate change may also explain aspects of human evolution.The approach takes existing knowledge of the geographical spread of other species through the warming and cooling of the ice ages to provide a model that can be applied to human origins.

“No one has applied this knowledge to humans before,” said Dr John Stewart, lead author on the paper and researcher at Bournemouth University.

“We have tried to explain much of what we know about humans, including the evolution and extinction of Neanderthals and the Denisovans (a newly discovered group from Siberia), as well as how they interbred with the earliest modern populations who had just left Africa. All these phenomena have been put into the context of how animals and plants react to climate change. We’re thinking about humans from the perspective of what we know about other species.”

Climate is believed to be the driving force behind most of these evolutionary processes, including geographical range change. It dictates which species are where at what time, driving their geographical spread or contraction.

Dr Stewart continued: “Ultimately, this model explains why Homo sapiens as a species are here and the archaic humans are not.”

The research also leads to interesting conclusions as to how and why Neanderthals, and indeed the Denisovans, evolved in the first place…

    No silly, climate change is a liberal myth just like welfare and the clitoris.

    Hear that? That’s the sound of conservatives’ brains exploding.

    It was definitely the mushrooms.

      It’s funny how far they’ll go to avoid that explanation.  “It was tools… they had tools it made them smarter… no it was climate change… yeah… etc”.  Just research the flippin mushrooms theory already, it’s bloody obvious and guess what – mushrooms exist, they aren’t just a murky hand-waving hypothesis.

        Mushrooms?

        Ah. Terrence McKenna certainly thinks outside the box…

        Bloody obvious?  More like painfully obvious!

  • Mr Willow

    That’s ridiculous. . . Human evolution was the result of alien gene slicing experiments. 

    The History Channel said so.

      The History Channel gets more shit wrong that it gets right.

        Boy, you sure know how to detect sarcasm, mm-hmm.

    As long as there are dozens of climate change protesters in
    the streets and millions in the world of science not joining them, exaggeration
    of climate change crisis is painfully obvious. Scientific exaggeration of
    crisis trumps all scientific consensuses leaving us without a crisis and a
    little tiny catastrophic climate crisis is only possible in Harry Potter
    movies.

    1-Occupywallstreet does not support climate change. (carbon
    trading stock markets ruled by banks)

    2-Obama has not mentioned any climate crisis in his last two
    state of the unions.

    3-Canada pulled out of Y2Kyoto last year.

    4-And as long as the scientists sit and watch the world walk
    away from their warnings, exaggeration is obvious. Deny that.

    Today’s climate change crisis believer is tomorrow’s end of
    the world freak.

    If there is any truth in that then it would mean that by merely producing generation after generation in artificially created environments (ghettos) using occult architecture with them suffering ,say, severe and chronic gastric and psychological distress would allow for permanent underclasses to be created and used to stabilize populations at their lowest level through immigration, need for welfare etc. Like the third world or impoverished first world urban groups. One could then conclude that nothing ever happens by accident like war, disease and even economic boom and bust. Ridiculous. They wouldn’t do that…I am totally outraged by the very thought of it..Great seizers ghost sic eh?
