Evolution of earliest horses driven by climate change

The earliest known horse, Sifrhippus sandae, evolved to become smaller over time as the planet warmed. Scientists have now found that rising temperatures directly drove this 'dwarfing' phenomenon, with a one-to-one shift in body size. This study has implications for how animals may respond to future climate change.
