Why did horses and camels go extinct in North America?
The end of the Pleistocene epoch — the geological period roughly spanning 12,000 to 2.5 million years ago, coincided with a global cooling event and the extinction of many large mammals. Evidence suggests North America was hardest hit by extinctions. This extinction event saw the demise of the horse in North America.

Why do scientist believe horses disappeared from the Americas?
Summary: A Johns Hopkins paleobiologist has uncovered clues that the horses (and camels and rhinos) that roamed North America millions of years ago went extinct because of climate change that radically changed their food supply.
Why did large mammals go extinct in North America?
The end of the Pleistocene in North America saw the extinction of 38 genera of mostly large mammals. As their disappearance seemingly coincided with the arrival of people in the Americas, their extinction is often attributed to human overkill, notwithstanding a dearth of archaeological evidence of human predation.

Why did all the giant animals go extinct?
The extinction of megafauna around the world was probably due to environmental and ecological factors. It was almost completed by the end of the last ice age. It is believed that megafauna initially came into existence in response to glacial conditions and became extinct with the onset of warmer climates.
Where did camels and horses come from?
Camels and horses instead went westward from the Americas, where their respective species had developed. Horses originated in North America 35-56 million years ago. These terrier-sized mammals were adapted to forest life. Over millions of years, they increased in size and diversified.
