SSC MTS EXAM

Detailed explanation-1: -Homologous features If two or more species share a unique physical feature, such as a complex bone structure or a body plan, they may all have inherited this feature from a common ancestor. Physical features shared due to evolutionary history (a common ancestor) are said to be homologous.

Detailed explanation-2: -Evolution of homologous structures by adaptive radiation explains similarities in structure when there are differences in function. Populations of a species can gradually diverge into separate species by evolution.

Detailed explanation-3: -Adaptive radiation is a concept in evolutionary biology where the number of species with a common ancestor increase rapidly however they are characterised by great morphological and ecological variations. So, the correct answer is ‘Divergent evolution’.
