What is the bear's bear?

Bear Cave was a Pleistocene animal that developed several million years ago and extinct at the end of the last ice age, about 20,000 years ago. Unlike the more well -known brown bear, which uses caves only for hibernation, cave bears spent much more time in the caves, as evidenced by fossil findings that this species is mostly in caves. In one cave in Romania, Peştera Urşilor (Bears' Cave), 140 Bearswere Caves found. This probably refers to several generations of an animal living in the same cave.

It is likely that people are responsible for the extinction of the bear's bear due to the competition for the warm cave shelter. However, the cave bear would not give up without a fight - the species was about 30% larger than a brown bear, with a weight of up to one short ton (1000 kg) and a height of the 3.5 m arm. consumed herbs, grass, berries and honey from wild bees. Strictly speaking, the bear's bear was omnipotent, except for the summer when he lived on a diet with a nationwide.

Being highly dependent on plant material for food and cave bears suffered throughout the Pleistocene, which was the time of temperature, glaciers and retreating forests. When the forests disappeared, they were replaced by wide, cold grassy steppes that did not provide enough food. This in combination with the human competition led to the demise of the animal.

In May 2005, scientists in California were able to restore the bottom of the bear tooth a cave that lived between 42,000 and 44,000 years. This DNA was seized and was revealed by 21 bear genes of the cave. This is one of several examples of the successful recovery of genetic material from Edruha XTint and increases the possibility that the cave, along with other Pleisto -cenal animals, can be re -created using biotechnology in a not very distant future.
