Question

What does the term 'adaptive radiation' describe in evolutionary biology?

पर्याय

• The process of evolution of different species in a given geographical area, starting from a point and radiating to other areas of geography and habitats

• The ability of organisms to survive high levels of radiation exposure

• The formation of new species through the mixing of genes from different populations in one location

• The spread of a single species across multiple continents without any genetic changes

Answer 1

Adaptive radiation is specifically defined as the process of evolution of different species in a given geographical area, starting from a point and radiating to other areas of geography and habitats. The term combines 'adaptive' (suited to a particular environment) and 'radiation' (spreading out from a single point into many directions), describing branching evolution from one ancestor into multiple related species adapted to different ecological conditions.
