How are two different species most likely to evolve from one ancestral species?
A)sympatrically,by a point mutation affecting morphology or behavior
B)allopatrically,after the ancestral species has split into two populations
C)phylogenetically,due to heterozygote advantage in hybrids

Question

Quizplus · Accepted Answer

The most common way for two different species to evolve from one ancestral species is through allopatric speciation, which occurs when a population of the ancestral species is split geographically and isolated from each other. Over time, different mutations and selective pressures can lead to genetic and phenotypic differences between the two groups, ultimately resulting in the evolution of separate species. Sympatric speciation through a point mutation affecting morphology or behavior is less common, and phylogenetic speciation through heterozygote advantage in hybrids is a theoretical concept that has not been observed in nature.
