Chapter 16: Evolution of Populations

Chapter 16: Evolution of Populations. When Darwin developed his theory of evolution, he did not understand: how heredity worked. This left him unable to explain two things: a. source of variation b. how inheritable traits pass from one generation to the next.

Charles Darwin

Charles Darwin. Darwinian Natural Selection. Individuals within populations are variable. The variations among individuals are, at least in part, passed from parents to offspring. In every generation, some individuals are more successful at surviving and reproducing than others.

Mechanisms of Evolution

Mechanisms of Evolution. Goal(s): 1 ) Understand the four mechanisms of evolution, how each causes evolution, how these mechanisms (potentially) interact to produce this change, and why evolution is relevant to me. Outcome(s): 1) Analyze a dataset and propose a mechanism for evolution.
