Think about the pattern of human dispersal. Given what you know about the founder effect, would you expect populations native to South America to be more or less genetically diverse than those native to North America? Explain your reasoning.

Summary Introduction

To explain: The population native to South America to be more or less genetically diverse than those native to North America based on founder effect.

Concept introduction: Evolutionary biologist, Ernst Mayr, proposed the founder effect. From a main population, a small group of individuals move to another geographical area. The newly migrated individuals will have to mate among themselves, as they are away from the main population. This decreases genetic diversity.

Explanation

Human evolution studies include migration pattern of human population across the different continents. Based on those studies, it is known that individuals migrated from North America to South America. Founder effect in great lengths reduces the genetic diversity...
