It's true – unicorns DO exist, they're just not quite the elegant, white ponies you imagined… A ground-breaking fossil discovery could prove that the extinct 'Siberian unicorn

' lived much later than previously thought – walking the Earth with humans.

In what year did unicorns exist?

The two were thought to have split about thirty-five million years ago, but may even have been as late as forty-seven million years ago. The unicorn might not be very old at all, and might have still been kicking until 39,000 years ago.

Why can't unicorns exist?

Perhaps horses develop in a way that cannot be easily modified to produce a unicorn, so such creatures have never arisen. Or maybe unicorn-like animals have been born in the past but because there is no advantage for a horse to have a horn, such creatures did not thrive and were weeded out by natural selection.
