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.

Ты рисковал собой не раз шутя
И знаешь, что такое боль
Ты в пьесе жизни выбрал для себя
Нелегкую роль
Приходится тебе друзей терять
Жестокий принимая бой
И каждый раз в нелегкий спор вступать
С самою судьбой

Припев:
Ради жизни и ради мечты
Каждый день без усталости ты
В поединок с неправдой вступаешь опять
Долг и честь эту службу нести
Быть преградой у зла на пути
Ради правого дела собой рисковать

Не раз людей от беды
Источник teksty-pesenok.ru
Опасность видя в двух шагах
В себе преодолеть был должен ты
Сомнения и страх
Лишь только тот кого нельзя согнуть
мир от зла
Ты сам однажды выбрал этот путь
И должен идти

Ради жизни и ради мечты
Каждый день без усталости ты
В поединок с неправдой вступаешь опять
Долг и честь эту службу нести
Быть преградой у зла на пути
Ради правого дела собой рисковать
Конец связи...

Все что нам нужно - немного удачи,
Удачу и штык берем мы с собой.
