The structure of the human hand and the bear claw are very similar. The largest male Kodiak bears can weigh up to 1500 lbs., and the smallest female sun bears can weigh as little 50 lbs.ĭ. Kodiak bears and polar bears are the largest bears.
There is a wider range of size between the different bear species. In all species of bear, the male is larger than the female on average. While most bears live in forests, the polar bear lives in the icy conditions of the Artic. Bears adapted in various ways for different environments. As the desert in Northern Africa expanded, it reduced the woodland habitat where the Atlas bear lived.Ĭ. The environment also had an impact on the extinction of the Atlas bear. From records, it seems thousands of bears were taken and made to fight with other animals like lions and tigers. The Roman Empire used many animals from Northern Africa to fight in spectacular competitions. Scientists today believe the Atlas bear to be extinct. While bears did live in the Atlas Mountains of Africa for a period of time, there are no species of bear living in Africa at this time. We can see from these different adaptations how bears evolved from a common ancestor to have the traits they have today.ī. The different adaptations each species of bear has for its environment is one of the facts that helps us learn about evolution.
Bears live all over the world, and the different species inhabit various geographic regions. There are only 8 extant species of bear on Earth now. For over 30 million years, bears in one form or another have roamed the Earth.
