The species of Heffalumps live on the planet Zurg. Once there was an earthquake and an entire island of the Heffalump people were separated from the rest of the population. Millions of years later this separation continues with no contact between the two (the island is surrounded by lava; not like on earth
Where we have water). What is the term for the changes that likely occurred between these two groups?

Question

Quizplus · Accepted Answer

Genetic drift refers to the change in the frequency of existing genes in a population due to random events, such as the separation described. Over millions of years, with no contact between the two groups, random changes in gene frequencies would likely lead to significant differences between the populations.
