similar structures that evolved independently in different organisms due to serving similar purposes

What is the order of classification? (largest to smallest)

Natural selection is

• survival of the fittest
• humans change
• two species are the same
• more animals survive

Why don't all living things become fossils?

• because some living things are too big
• because some are subject to catastrophism and others are not
• because environmental conditions have to be just right (for formation & to prevent decay)

Why are vestigial structures evidence for evolution?

• They are useful in the organism and show natural selection at work.

• They are not useful in the organism but they were probably useful in some ancestor of that species.

• They show that these organs or behaviors help an organism adapt to new environments
