Many scientists-zoologists studying pandas carry these animals to family of bear. However other researchers it is considered to be that these lovely plush creatures closer on specific relationship to raccoons. And the third researchers allocate them in separate family.
Origin
Most of supporters of the theory of evolution consider big pandas (in a different way a giant panda) by the live minerals having family relations with the died-out bears agrioteriya which something remind external signs.
Most likely, the ancestor of big pandas, as well as modern brown or Himalaya bears, was a predator.
The carried-out analyses on morphology, etymology, anatomy and physiology E. Tennius, the Australian researcher in the field of paleontology, showed that the big panda treats on 16 common features bears, on 5 – raccoons, and 12 differences inherent only in this look. Therefore most of scientists costs that the panda needs to be carried in separate family.
Structure of teeth and food allowance
Most likely, in connection with scarcity of animal food, big pandas passed to vegetable food, that is to a bamboo and some other components of the green world. On the passing menu type from predatory type on vegetarian, specifies the structure of their teeth adapted both for mastication of a bamboo, and for absorption of meat. So how many teeth at a panda? Their general quantity - 40 pieces. From them a special role is played located from above from two parties up to 4 lozhnokorenny teeth and up to 2 real molars and also by the lower two three of lozhnokorenny and real molars. Such structure allowed to adapt to pandas to firm vegetable food. The truth a stomach and an intestinal path of animals, does not digest completely even young bamboo growth. The system of digestion in pandas is much weaker, than at other herbivores. Therefore big pandas not to lose in weight, are forced to absorb food all the time, about 15 hours a day.
Today big pandas - the endangered species included in the international Red List. The reason - development by the person of areas of dwelling of pandas.
It is considered to be that the panda eats one bamboo. It and in the truth the main food, but big pandas often fill up the reserves of fat and proteins not only plants. The animal does not exclude also eating of small animals, insects, fish which is capable to be caught (more often sick or wounded) does not disdain also drop. Sometimes, as well as bears, ruins bee nests. Such least variety of food also allowed a big panda to live up to now.
