Introduction to BearsAll bears are carnivores and they are viewed as the youngest of all that fall into that particular category. They are believed to have evolved 35 million to 55 million years ago. Their ancestors are believed to have been dog like in size and shape. However, they had larger ears and sharper teeth. The ability of early bears to adapt to a variety of living conditions accounts for why they have been able to be so diverse. It is this diversity in location that also lead to the development of many different species of bears. Each one changed in ways that allows them to be able to live in a given area. For example the coloring of their fur as well as the thickness of it for blending into their surroundings. The types of foods that they eat and where they get them from also is geographically diverse. They are fascinating to be able to watch in their natural setting if you ever get the chance.
There are many different species of bears that are found throughout the world. Most of them are either black or brown in color. The one that stands out is the Polar Bear who is white. This is due to the fact that they live in the very cold regions with lots of snow. The white coloring helps them to easily blend into their surroundings. Bears are well known for their size and powerful strength. They are often the winners in the wild when there is a battle among them and another animal. The warning signs of a bear not being happy include standing up tall and roaring. It is said that you should make yourself appear as large as possible when a bear is in such a stance. Chances are they will run away from you instead of attacking.
Most bears are content to live in the wild and to roam around looking for food. They consume a variety of foods including nuts and berries. They can be found in the lowlands or the wetlands. They can also be found on the open plains or in heavily wooded areas. Bears seem to do very well in captivity as well. In fact, they are among the most popular attractions at zoos all over the world. There are several species of bears that have already become extinct. This is due to slow reproduction rates and the destruction of their environment. There are many other species of bears that are also endangered. Even with active groups doing all they can for awareness purposes and to help get their numbers up there is the risk. If you want to protect the bears find out how you can donate time or money to these worthwhile causes.
