Question

what are the two phases of speciation?
□ change of existing species
□ creation of new species from a single mutation to an individual
□ splitting of existing species into two or more different species

Explanation:

Speciation has two main phases. The first is the change of existing species (accumulation of genetic changes over time), and the second is the splitting of existing species into two or more different species (when populations diverge enough to become reproductively isolated). The option "creation of new species from a single mutation to an individual" is incorrect because speciation is a population - level process, not caused by a single mutation in one individual.

Answer:

The two phases of speciation are:

• change of existing species
• splitting of existing species into two or more different species
