An ancient global warming event shrunk the earliest horses down to the size of scrawny housecats, according to new research that could have implications for what mammals might look like in a future warming world.
During what's known as the Paleocene-Eocene Thermal Maximum, or PETM, about 56 million years ago, a massive release of carbon into the atmosphere and oceans boosted average global temperatures by about 10 degrees Fahrenheit (5.5 degrees Celsius) over 175,000 years. Mammals responded to this climate change by shrinking, with about one-third of species getting smaller.
Now, new research reveals that these changes occurred in lockstep with temperature fluctuations during the period. The earliest-known horse Sifrhippus started out this period as a bit of a pipsqueak: The animals weighed only about 12 pounds (5.6 kilograms) on average, about the size of a miniature schnauzer.
But by 130,000 years into the PETM, Sifrihippus had shrunk down to only about 8.5 pounds (3.9 kg), the size of a small housecat. These humble horses then experienced a size rebound, bulking up to about 15 pounds (7 kg) in the last 45,000 years of this warm period, putting them on par with the average bichon frise.

A pony walks into a bar and says “Bartender, may I have a drink?”
Bartender says “What? I can’t hear you. Speak up!”
“May I please have a drink?”
“What? You have to speak up!”
“Could I please have a drink?”
“Now listen, if you don’t speak up I will not serve you.”
“I’m sorry, I’m just a little hoarse.”

Sorry to say that you got this one wrong, GrandJediMasterYoda.
Al Gores caveman ancestor, Croman Gore, was busy inventing the RockNet in those days so he was not able to turn his attentions to the daily weather.
P.S. Get a shorter name
Amazingly, no one has correlated original furlong length, to the breed size. Idiots.
Well, look at it this way - 3 foot humans would relieve overcrowding (sarcasm)
I know!!
The same thing happens when I put my clothes in the dryer!
If global warming shrunk horses to the size of a cat, why are people taller now than they were back in olden days?
I’d like to see the supporting research on this one. Not passing the smell test yet.
