Divergent natural selection
WebJun 16, 2009 · Speciation by natural selection occurs by 2 general mechanisms (4, 7).The first of these is ecological speciation, defined as the evolution of reproductive isolation between populations, or subsets of a single population, as a result of ecologically-based divergent natural selection (6, 8–10).Under this process natural selection acts in … WebOct 4, 2024 · The image above shows how the beak sizes and shapes of finches that live on the Galapagos Islands (Darwin’s Finches) have diverged over time in response to natural selection pressures from the …

WebWe focus here on the contributions of divergent natural selection to population divergence. Such divergent selection will pull apart allele frequencies between populations at loci under selection ... WebMay 26, 2024 · The term divergent evolution was first introduced by J. T. Gullick. Divergent evolution occurs when differential selection pressure or evolutionary driving force (both biotic and abiotic) acts on a subgroup of species which leads to accumulation of variations that favors better adaptation (Schluter 2001 ). The buildup of these adaptive traits ...
