Question

Name the process/term for the following statements.

A gradual and continuous change in the characteristics of a species over time.

Answer 1

Evolution:

1. Evolution may be defined as the gradual changes that occur over a long period of time resulting in the formation of new life forms, from the pre-existing forms.
2. The living species were simple in the beginning, but with gradual and slow changes, they evolved into complex species.
3. Such changes occur due to changing environment and lead to an idea of evolution.

Hence, a gradual and continuous change in the characteristics of a species over a long time is evolution.
