Chapter 20, Problem 9TYK
Summary Introduction
To review:
The characteristics that one observes in the living organisms that have adapted to the environments in which their ancestor lived, rather than to the environments in which they live today.
Introduction:
Charles Darwin is famous for his theory of natural selection. His theory explains that organisms that are living in the modern environment today carry all the favorable traits from their ancestors. These traits are the result of natural selection, which allowed them to survive over other animals.
