Chapter 18.2, Problem 2C
Summary Introduction
To explain: The difference between the mechanism for evolution proposed by Lamarck and the one proposed by Charles Darwin.
Introduction: Charles Darwin and Lamarck have proposed the process and mechanism of evolution at different times in their own ways. Although Darwin’s theory is more accepted as an explanation for the process of evolution, Lamarck’s theory was considered an explanation to be reasonably appropriate until the rediscovery of Mendel’s basis of heredity characters. Theories given by Lamarck and Darwin have some points that agreed with each other, while others did not.
