Bears are often contrasted with tigers as one of the most powerful land animals. In the Far East (Khabarovsk Territory) bears and tigers live in the same territory. If the amber, or otherwise the Amur tiger (weight 170-200 kg, maximum 427 in captivity ), will encounter a brown bear (weight 250-300 kg), then the tiger prefers not to associate with such a bear.
But some tigers (adult males) prey on young brown bears and adult females, which are usually smaller than the tiger itself. When the tiger and bear are fighting, the place of the fight is a terrible sight. The defeated, as a rule, is eaten.
And on the white-bears (a mass of 120-140 kg), the tigers even specifically hunt, often picking them out of the hollow. The tiger suffices a brown bear for 10 days. The Just Russia party chose the tiger as a symbol as a competitor to the bear .
The first bears appeared in Europe to the beginning of the Miocene, about 25-30 million years ago. The most close to the Miocene bears are large pandas and spectacled bears. The rest of the bears were formed later. In Pliocene, about 2-6 million years ago. In Pliocene, there were the largest number of genera and species of bear. The main genus is considered to be the genus Ursus. The brown bear, represented now only by one species, was formed 1,800,000 years ago.
