Convergent evolution produces analogous characters as a result of:

• similar environments.
• sharing a common ancestor.
• shared derived characters.
• different environments.

The similarity between the bird wing and moth's wing are:

These organisms:

Natural selection is the process:

• that change occurs in the genetic characteristics.
• organisms that are better adapted, reproduce at a greater rate.
• use and disuse of a characteristic.
• baseball players pass on their strong arm muscles to their children.

The major idea that Darwin presented in his book The Origin of Species was:

• species change over time and don't compete.
• elephants and bacteria change constantly.
• animals change, but plants remain the same.
• species change over time by natural selection.
