Adaptation in the Caribou Adaptation in a population of living things happens as a result of an adaptive trait. This is any inheritable trait that increases it’s survival rate so that it can live longer, reproduce longer, and have more offspring (that also have that trait). Adaptive traits can improve animals find food, make a safer home, escape predators, survive cold or heat or lack of water. The caribou have developed many helpful adaptations for living in the far north. These adaptive traits include have large, fur-covered hooves for gripping the ice as they make their way across the frozen landscape in their annual migrations. They also have a warm, thick coat to protect them both from extreme cold in winter and insect attacks in summer. They can survive eating only lichens that grow on the barren rocks on the tundra. These physical adaptations make it possible to survive in their harsh, northern climate.
