scientist nearly gives game away!

Climate change over the past two million years has boosted human evolution by forcing us to adapt to changing conditions and allowing us to migrate to new areas.

Researchers found that far from hindering our development, periods when the earth is either cooling or warming up have actually been highly beneficial.

Experts from the National History Museum and Cambridge University have identified five key time periods when shifts in global climate have resulted in accelerated social and genetic evolution.

Chris Stringer of London’s Natural History Museum and author of The Origin of Our Species told the Sunday Times: ‘Climate change has been a major player in our evolution. It created the conditions that encouraged our early ancestors to come down from the trees and later to spread out of Africa and across the globe. It made us what we are today.’

The Royal Society is holding a conference this week where details of recent research will be released. The scientists are keen to point out they are not suggesting that modern global warming is beneficial.
