_______ is a way of reconstructing evolutionary history based on derived characters.

  1. a. Cladistics
  2. b. Linnaean taxonomy
  3. c. Convergent evolution
  4. d. Divergent evolution

Summary Introduction

Concept introduction: An approach in biological classification system that categorizes organisms based on their common ancestors is known as cladistics. A group of organisms that share one or more defined derived characters are called clade. The study of evolutionary relationship between those clade comes under cladistics.

Explanation of Solution

Reasons for correct answer: Cladistics is the method of classification of organisms that aims to identify and take account of only those shared characters, which can be deduced to have originated in the common ancestor of a group of species during the course of evolution. It is a way of reconstructing evolutionary history based on derived characters.

Hence option a. is the correct answer.

Reasons for incorrect answer:

Option b. is given as “Linnaean taxonomy”. It is the system of naming species and categorizing them into taxa based on similarities only...
