As a biologist, you are researching a population of moles. in the course of your research, you identify a nearby population that occasionally comes into contact with your study population. what best describes the evolutionary process at work?

a. natural selection
b. gene flow
c. mutation
d. genetic drift
e. artificial selection

The evolutionary process at work is best described by option B. gene flow

Explanation:

Gene flow also known as migration is any movement of individuals, and/or the genetic material they carry, from one population to another. If gene versions are carried to a population where those gene versions previously did not exist, gene flow can be a very important source of genetic variation. In this case, the nearby population migrates to the mole population. The diagram is a good description of the Gene flow process.
