A population of deer is separated by an emerging volcano. The two populations come back into contact 200 years later, but are in
capable of breeding. Which of the following best describes the process that occurred? A)adaptation
B)speciation
C)convergent selection
D)stabilizing selection
Speciation is the term used to refer to the division of a lineage that produces two or more different species. In a nutshell, we can say that this is the process of the emergence of a new species, and the crucial event for this to happen is reproductive isolation. This reproductive isolation impedes the gene flow, therefore, obeying the biological concept of species, we say that a new species has emerged.
An example of speciation is shown in the question above, where a volcano separated two species and left them in reproductive isolation. The result of this was that two populations became so different from one another that they became unable to breed, creating new species.
