Multiple Choice New species arise when a. a portion of the population becomes isolated from the remainder of the population and
Mandarinka [93]

Answer:

a. a portion of the population becomes isolated from the remainder of the population and experiences different selective pressures

Explanation:

This is an example of allopatric speciation Allopatric speciation is a form of speciation (formation of new species) that occurs as a result of geographic isolation. This means that a part of population becomes physically separated from the initial main population. There is no gene flow between these two populations and as a result the two populations  reach a high level  of genetic divergence. They can no longer interbreed which means they become two different species (speciation).

New populations evolve as result of mutation, genetic drift and natural selection.

For example, Galapagos finches are isolated from others by the ocean (geographic isolation).  Because of the isolation, the finches don’t breed with one another. So, they developed unique characteristics and became endemic.
