Elephants have a 6th toe

London - A bony growth in elephants' feet is a sixth "toe" that helps the world's heaviest land mammal keep its balance, scientists said on Friday.

The growth protruding from the back of elephant's feet was discovered in the 18th century when a Scottish surgeon dissected one of the creatures for the first time.

Researchers had been baffled by the piece of bone but a new study in the US journal Science claims to have solved the mystery.

While not a true toe, the growth has developed the same function as a toe - giving the behemoths much-needed help in supporting their colossal weight as they lumber across African plains and through Asian jungles.

"It is performing the function of a toe in supporting the elephant's weight," said lead author Professor John Hutchinson, of Britain's Royal Veterinary College.

"It is a little weird piece of bone that has been elongated during evolution into quite a long piece of bone."

The researchers used techniques including X-rays, dissection and an electron microscopy in their study.

The elephant's five conventional toes point forward but the extra "toe" points backward to give extra support.

A similar phenomenon can also be observed in pandas and moles, according to scientists. A panda's "sixth finger" helps it to grip bamboo, while the extra digit helps moles to dig.

The researchers studied elephant fossils to discover when the bone first appeared and believe it was around 40 million years ago, as elephants got bigger and became more land-based.

    @Frank 200 hundred years ago Africans would not have known that elephants had any toes.

    This is fantastic news, it's really made my Christmas. All my life I have been having sleepless nights wondering if elephants had more than five toes.Going out tonight to celebrate big time.

    Hang on a minute there, I'v been too hasty in my celebrations. These idiot scientists say this "toe" has been around for 40 million years. How can this be? According to Creationists the world has only been around for 6000 years. You just can't trust scientists, whoever heard of a 40 million year old elephant? 6000 year old elephant I can believe, but 40 million years? Liars!
