Extreme Climate Change Millions of Years Ago Caused Mammals to Shrink
The ETM2 temperature increase might sound familiar. It’s roughly the level of warming scientists suggest we may see if governments around the world don’t de-carbonize their economies by reducing the amount of fossil fuel emissions they pump into the atmosphere.
One of the effects of those extreme climate changes millions of years ago was the dwarfing of mammals. New research, published in the journal Science Advances, suggests that not only do warmer temperatures shrink the body size of mammalian species, but the warmer it gets, the bigger the change.
