- variation
- adaptation
- adaptations have come about through variation through 1000's of generations
- cold climates
- the polar bear
- a white appearance to camouflage from prey in snow and ice
- thick layers of fat and fur for insulation against the cold
- small surface area to volume ratio to minimize heat loss
- a greasy coat which sheds water after swimming
- the snowshoe hair
- white fur in winter and reddish brown fur in the summer
- camouflaged from preditors
- white fur in winter and reddish brown fur in the summer
- the polar bear
