What is evolution? What is not evolution?

Today we learned about Charles Darwin and other leading scientists who helped shape the theory of evolution.

Homework: Watch the video clip below and answer the questions in your packet. In case you have "misplaced" the packet, the questions are below the video as well.

Questions (which are adapted from the PBS teacher's website)
1. Below are four components of natural selection. Describe each of these components.

Genetic variation:

Overproduction of offspring:

Struggle for existence:

Differential survival and reproduction:

2. What kinds of limited resources can create a struggle between individuals in a population?

3. What kinds of variable traits within a population might natural selection act upon?

4. How does natural selection affect the genetic variation within the next generation of the same population?
