How are two different species most likely to evolved from one ancestral species?New species form by speciation, in which an ancestral population splits into two or more genetically distinct descendant populations. Speciation involves reproductive isolation of groups within the original population and accumulation of genetic differences between the two groups.
How could 1 species separate into 2 species?Often a physical boundary divides the species into two (or more) populations and keeps them from interbreeding. If separated for long enough and presented with sufficiently varied environmental conditions, each population takes its own distinct evolutionary path.
Can two different species evolve into the same species?Two species can merge through hybridization, or through obligate endosymbiosis. It's unlikely this would happen through convergent evolution. Convergent evolution happens when different lineages independently acquire the same adaptations.
What are 2 reasons a species might evolve to become a new species?Thus, new species form when individuals from diverging populations no longer recognize one another as potential mates, or opportunities for mating become limited by differences in habitat use or reproductive schedules.
