a. sympatric speciation; vicariance
b. allopatric speciation; vicariance
c. sympatric speciation; dispersal
d. allopatric speciation; dispersal
The CORRECT ANSWER IS d.
d. allopatric speciation; dispersal
Explanation:
Allopatric speciation takes place either via dispersal, when some members of a species shifts it's habitat to a separate geographical area which leads to differentiation of the initial group into separate diverse varieties or species(as in our case study).
Allopatric speciation through dispersal could results in multiple speciation leading to an individual original species producing diverse new species; this occurrence is called adaptive radiation.
In some scenario, a population of an individual species disperses all over a region with each locating a separate niche or isolated habitat. In the course of time, the diverse demands of their just formed lifestyles causes multiple speciation events that comes from a singular species.
