1. Two giants lived in the Altai Mountains in Kazakhstan. They were brothers. The younger brother loved music and singing, so one day he made himself an instrument out of wood. He gave it a long neck and two strings . He played his new instrument all day and sang. It made him very happy. 2. The older brother didn’t like music. He wanted to be famous. He decided to build an enormous stone bridge across the big river. It was a fast and dangerous river and no one could cross it. “My bridge can make me famous”, he thought. So he started to build. It was hard work, but he was strong.
But his younger brother didn’t help him. He didn’t want to be famous. He only wanted to play his instrument and sing.
The older brother became very angry. “You never help me!” he shouted. “You only play your silly music all day long! He snatched the instrument from his brother’s hands and smashed it against a rock. He hit the rock so hard that you could see the instrument’s shape on the surface.
Many years passed. People found this stamp and began to make new dombras, and the music, which was silent for much time, sounded again.

So why did a change in climate 36,000 years ago drive the Siberian unicorn extinct, but not the woolly rhinoceros or the saiga?

To answer this question, our study took fossil bones from the Siberian unicorn, woolly rhino, and saiga, and looked at the nitrogen and carbon they contained — as differences in these elements reflect an animal's diet.

We found that before 36,000 years ago the saiga and the Siberian unicorn behaved very similarly, eating grass almost exclusively. After this point, the carbon and nitrogen in saiga bones showed a major dietary shift towards other plant types.

But shifting from a grass diet proved too difficult for the Siberian unicorn, with its special folded wear-resistant teeth and a low-slung head right at grass height.

Relatives such as the woolly rhino had always eaten a more balanced array of plants, and were much less impacted by a change in habitat.

Importantly, the change in climate that drove the Siberian unicorn extinct was actually much less pronounced than those which occurred during the Ice Age that followed. Or the changes that we will face in the near future.

The story of the Siberian unicorn is a timely reminder that even subtle changes in plant distributions can have devastating knock-on effects for large animal species.

Legends of the unicorn, or a beast with a single horn, have been around for millennia.

Some have argued that the horn of the rhino may have been the basis of myths about unicorns, although other animals - such as the tusked narwhal - are more likely contenders.
