Polar bears and other bears have very different personalities. Polar bears live in cold places, while brown bears prefer warm and sunny places. Their different characteristics allow them to adapt to their environments.
Natural selection
Polar and other bears have very different personalities. Polar bears live in cold places, while brown bears prefer warm and sunny places. Their different characteristics allow them to adapt to their environments.
The polar bear’s white fur helps them blend with the snow and protects them from predators. Also, polar bears have thick layers of fat and fur so they don’t freeze to death. They also have a greasy coat that sheds off after swimming so they don’t lose heat.
Adaptation
Polar bears’ big and strong legs help them bend and move large objects like wood or rocks. The thick and fuzzy layers of polar bears’ fur almost feel like wearing a sweater. It acts like a raincoat.
Theory of evolution
About 111 to 116 thousand years ago, a group of brown bears split from their group and went to Antarctica, where they were trapped. After thousands of years, they adapted to their environment, which turned them into our well-known polar bears.
Research
Scientists in the field place satellite collars on a select number of bears every season in fall, always in the same areas. The technology lets research teams follow polar bears across Antarctica from a warm office thousands of miles away.
Polar bears are so distinct compared to other bears, which makes them unique. No other bear can be as talented and as good-looking as them. Their adaptation has changed them from the brown bears.
