Due to evolution, there are changes in gene pools over time because: B. Biogeographic isolation causes changes in gene pools that result from populations being separated over time.
What is an evolution?
Evolution can be defined as a process of gradual change in the characteristics and genetic pool (make-up) of the species of a living organism over several generations.
In Genetics, a scientific technique which is commonly used by scientist to determine evolutionary relationships between the gene pools of a population is the study of their fossils and biochemical similarity.
In conclusion, biogeographic isolation allow for the change of gene pools that result from populations being separated by several environmental or abiotic factors over time.
