Humans may be much shorter if global warming continues, according to the latest study.
A new study finds that ancient horses shrunk even smaller than their ancestors, a trend scientists say is likely the result of global warming.
Modern mammals, including humans, could be at risk of shrinking as a result of global warming, just as small prehistoric horses shrank to an even smaller size when temperatures rose 56 million years ago.
The proposal follows from a study of Sifrhippus, the first horse, 56 million years ago. Sifrhippus shrank from about 12 pounds average weight to about eight and a half pounds as the climate warmed over thousands of years, according to a report published by a team of researchers and reported in the journal Science on Thursday.
