The Evolutionary History and Spread of Our Species (Homo sapiens)

  1. a. Briefly describe the two major theories discussed in this chapter about the origin of modern humans.
  2. b. Which of these two theories would predict a closer relationship for the various modern human populations?
  3. c. Which of the two theories is best supported by the genetic evidence?

a.

Summary Introduction

To describe: The two major theories discussed the origin of modern humans.

Introduction: The hierarchical system of classification classifies and groups the living organisms into different levels based on the characteristics and properties they have in common. Humans refer to the mammals belonging to genus Homo. The humans belong to the species of Homo sapiens.

Explanation of Solution

One of the theories that describe the origin of modern humans is the Out-of-Africa hypothesis. This hypothesis states that the origin of modern humans was in Africa. After the origin, the humans migrated to different places.

Another theory explaining the origin of modern humans is the multiregional hypothesis...

b.

Summary Introduction

To determine: The theory that predicts a closer relationship for the modern human population.

Introduction: The hierarchical system of classification classifies and groups the living organisms into different levels based on the characteristics and properties they have in common. Humans refer to the mammals belonging to genus Homo. The humans belong to the species of Homo sapiens.

c.

Summary Introduction

To determine: The theory that best supports genetic evidence.

Introduction: Genetics can be defined as a branch of biology that primarily deals with the study of genes, variations in the genes and also heritable characteristics of organisms.
