Question

Answer 1

The bones in a bird are hollow, reducing its weight for flight, this is an example of ADAPTATION. The adaptive responses emerge as a consequence of different environmental pressures.

Adapatation and environment

Adaptation is an evolutionary process by which organisms adjust to the environment in which they live.

For example, the bones in a bird are hollow because this adaptive feature enables them to fly.

Adaptations are a consequence of the process of natural selection, i.e., the differential survival and reproduction of the fittest organisms.
