Question
Chapter 1, Problem 13RQ
(a)
Summary Introduction
To determine: The initial obstacle faced by the theory given by Darwin on natural selection in evolution.
Introduction: Evolution is a necessary process that happens with time as it helps the new generation in adapting according to the environment. The natural selection theory of evolution is one of the most accepted theories.
(b)
Summary Introduction
To determine: The ways that helped the natural selection theory in overcoming the initially faced obstacles.
Introduction: All the theories given by Darwin were not accepted by the biologists. Some are still in controversies. The theory of natural inheritance is widely accepted and was supported by the particulate inheritance principle.
