Chapter 1, Problem 5PDT

Summary Introduction

To explain: The contrasting points of Darwin’s ideas of the origin of species with the prevailing notions of that time.

Introduction: Before Darwin, it was Lamarck’s theory that was most accepted in explaining the evolution of organisms. Theory of evolution given by Lamarck and Darwin explained almost the same basic things, but Lamarck’s theory of evolution lacked certain scientific basis of explanation that made Darwin’s theory more acceptable at that time. Darwin emphasized more on common ancestry, whereas Lamarck’s theory did not give any importance to ancestry.
