How do wild horses trim their hooves?

A domestic horse is unable to wear their hooves down as nature intended. Wild horses maintain their own hooves by moving many kilometres a day across a variety of surfaces. This keeps their hooves in good condition as the movement across abrasive surfaces wears (‘trims’) the hooves on a continual basis.

“Overall, this makes forest elephants the slowest reproducing mammals known,” says Wrege. Orangutans are probably the closest mammal in terms of rate of reproduction – they give birth about every six to seven years. But orangutans begin reproducing in their teens rather than their twenties.

Why did horses lose their toes?

Their side toes first shrunk in size, it appears, before disappearing altogether. It happened as horses evolved to become larger with legs allowing them to travel faster and further.

Are horses prehistoric?

The prehistoric horse in North America evolved over a period of 50 million years. To date, scientists have pinpointed the original horse, Eohippus, which resembled a small dog. The horse has undergone multiple changes over the past 50 million years and today holds a place deep within the human heart.
