Textbook Problem

Unrelated species in geographically separated parts of a biome may resemble one another as a result of ______.

  1. a. morphologicaI divergence
  2. b. morphological convergence
  3. c. resource partitioning
  4. d. coevolution

Summary Introduction

Introduction: Descent with modification is known as evolution. It underlies the diversity and unity of life. Organisms found in the different parts of the earth are independently evolved adaptations to the environmental stresses that occur in that biome.


Reason for correct answer:

Option b. is given as “morphological convergence.”

In morphological convergence, two different species are adapted in a similar way to meet the needs of the same type of environment, for example, dolphins and sharks. Therefore, option b. is correct.

Reasons for incorrect answer:

Option a. is given as “morphological divergence”. In this type of evolution, the same species is adopted in different ways to meet the needs of different types of environment. Therefore, Option a. is incorrect.

Option c...
