Question

Evolution of different species in a given area starting from a point and spreading to other geographical areas is known as

• A. Migration.
• B. Divergent evolution.
• C. Adaptive radiation.
• D. Natural selection.

Answer 1

The correct option is C Adaptive radiation.

Evolution of different species in a given area starting from a point and spreading to other geographical areas is known as adaptive radiation. Darwin's finches are a prime example of an adaptive radiation. Fourteen or perhaps 15 species, all derived from a common ancestor, occupy individual ecological niches on different islands to which they are adapted, principally because of the size and shape of their beaks in relation to the food they eat.
Migration - seasonal movement of animals from one region to another.
Divergent evolution is the process of tracing back two or more species to their common ancestor.
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in heritable traits of a population over time.
