herbivore

The animal belongs to a herd of hefty herbivores who spend their days lumbering through an open landscape of conifers and gingkos, horsetails and monkey puzzle trees.

While the animals are herbivores, they can become highly aggressive when they feel threatened or their habitats are disturbed - and kill around 500 people every year in Africa.

Plants that are pollinated by insects and have to defend themselves against herbivores have evolved to be better adapted to different types of soil.

There were 61 species of large terrestrial herbivores -- weighing more than one tonne -- alive in the late Pleistocene, and only eight of these exist today.

In their classic theories of evolution, both Jean Baptiste Lamarck and Charles Darwin suggested that giraffes' long necks evolved to help them reach leaves high up in a tree, avoiding competition with other herbivores.
