Evolution of Tigers

There are exist 37 different species of cats. Cats evolved around 25,000,000 years ago and have been and are some of the most specialized mammals on the earth. The Siberian tiger is the largest cat in the world. The snow     tiger is slightly smaller than the Siberian tiger. Back in history larger cats have existed, but they were extirpated long time ago.  


The last Tasmanian tiger die on 1936. It is heartbreaking that such as fine animal is now extinct. Below you can see a video of this beautiful tiger. In general cats are very alike both in terms of their way of living and their behavior. They are especially adapted to hunt and kill and eat raw meat! All predators are adapted to hunting and eating meat and a special kind of living one could say, but the tigers in general, including the Snow Tiger, is perhaps more adapted than many other predators. Humans for example have relatively flat molars that we use for chewing food. The White Tiger does not have any molar teeth they only got what one could call cutting teeth that works the same way as a scissors does. In the front of their mouth they have two very large canine teeth. These are very different in size compared to the corresponding teeth seen in humans and approximately 50% larger than the similar teeth seen in polar bears.

In conjunction with this piece of information it should be mentioned that the polar bear, in general, is almost twice as big as the Siberian Tiger.
