WebDec 4, 2024 · The divergent evolution leads to speciation and works based on their variation in the gene pool of a population. If a reproductive barrier has separated two groups in the population, then different genes control various aspects of the ability of organism of survival and reproduction vary in frequency as gene flow is restricted. The Allopatric ...
WebDivergent evolution occurs when populations become isolated from each other, and when selective pressures differ among the populations. Divergent evolution will occur because different selective pressures favor different genetic traits in each population, and isolation prevents genetic mixing among the populations. Divergent evolution or divergent selection is the accumulation of differences between closely related populations within a species, sometimes leading to speciation. Divergent evolution is typically exhibited when two populations become separated by a geographic barrier (such as in allopatric or … See more The term divergent evolution is believed to have been first used by J.
