A family of raccoons living in the center of a forest leaves that area and joins a population of raccoons living near the edge of the forest. Over a period of years, a certain trait in the raccoon population living near the edge of the forest becomes more common. What factor caused the raccoon population to evolve? (Points : 3) migration genetic drift mutation genetic recombination



Answer :


the two raccoon families breed with one another. and also its part of Darwin's evolution theory, descents with modification and modification by natural selection. where the modification is a mutation. mutations are caused by a flawed trait/characteristic over a period of time, known as generations. they adapt to their surroundings in order to increase their chance of survival, that's why a certain trait will become more common over an amount of time.

Answer: The correct answer is-  migration.

The term migration can be described as the movement of organism/ population from one region to another region.

As per the information in the question, raccoons family living in the center of a forest leaves and joins a population of raccoons living near the edge of the forest.

Due to migration of new population, overall size of edge population is increased and because of interbreeding between raccoons, a certain trait ( that could be earlier present only in the edge population) in the raccoon population becomes more common over a period of years as now it would be present in both the former edge population as well as the migrant edge population.    

Thus, the factor caused the migrant raccoon population to evolve is migration.
