|
|
|
the inability of a species to breed successfully with related species due to geographical, behavioral, physiological, or genetic barriers or differences
|
|
|
A change in the allele frequency of a population as a result of chance events rather than natural selection. (example:natural disasters)
|
|
|
process by which a single species or small group of species evolves into several different forms that live in different ways
|
|
|
process by which unrelated organisms independently evolve similarities when adapting to similar environments

Detailed explanation-1: -The term divergent evolution is believed to have been first used by J. T. Gulick. Divergent evolution is commonly defined as what occurs when two groups of the same species evolve different traits within those groups in order to accommodate for differing environmental and social pressures.
Detailed explanation-2: -Hence, the correct answer is ‘Adaptive Radiation’.
Detailed explanation-3: -Divergent evolution occurs when a subgroup of a species evolves traits different from its ancestors. The trait usually sprung from selective pressures. Such pressures drive natural selection and compel organisms to evolve.
Detailed explanation-4: -Adaptive radiation is the process by which one species evolves into two or more species. This occurs as a result of different populations becoming reproductively isolated from each other, usually by adapting to different environments.
