Adaptations are
the result of evolution in different living organisms. This process occurs amazingly
through gene mutation but it takes a very long period in time. Adaptation
processes occur to help species survive and thrive in the ecological balance of
life. Structural adaptations are physical features of an organism that adapted
through time. An example of this are the bills of a bird and the fur of bears
that they generally need for their survival; birds for hunting, and bears to
protect them from low climate areas.

seasons and hibernate during winter season. </span>
