Question

Genetic data suggest many frog species that live in Madagascar and India share a common ancestor that lived on the India-Madagascar landmass. Which statement best describes the divergence of frog species found in India and Madagascar?

Answer 1

Geographic separation led to divergence in the gene pool, resulting in a new species in each location.

Step-by-step explanation:

The scenario in the question described that the India- Madagascar landmass had a population of frogs living on the landmass. The landmass was separated into two landmasses with one landmass in India and another one in Madagascar. As a result, the gene pool of these frogs was changed at each side and each group of the frogs started to diverge and form new species. Gene pool can be described as the genes which a particular population has.
