The greatest genetic diversity of modem humans is found among the people of ______

  1. a. Europe
  2. b. Asia
  3. c. Africa
  4. d. North America

Summary Introduction

Concept introduction: Hominins are the group of all extinct human-like species and humans where they showed the unique characteristic of bipedalism. The Homo species’ fossils were discovered in several parts of the world based on which the human migration pattern was studied.

Explanation

Reason for the correct answer:

The human evolution initially began in Africa based on the fossil studies. Slowly migration occurred and population moved to Europe, Asia, Middle East, and Australia. Based on founder effect, genetic diversity of individuals away from the main population is always less than the main population as they have to mate between themselves. Africa households the main population, hence, the genetic diversity is greater there. In the rest of the populations, which migrated to Europe, Asia, Middle East, Australia, and North America, the genetic diversity is very less.

Option c. is given as “Africa” and since the genetic diversity of the populations in Africa is greater than other regions, the correct answer is option c.

Reason for the incorrect answer:

Option a...
