4) NATURAL SELECTION

Question 2

Vestigial Structures

Answer 2

Features existing in modern animals, even if they are no longer in use, for example the human appendix.

Question 3

Homologous

Answer 3

• similar structure
• different function
• ex: bats and whales have similar humerus bone structure, but bats use their humerus for flying and whales use their humerus for swimming

Question 4

Analogous

Answer 4

• different structure
• similar function
• ex: butterflies and bats have different wing structure although both of their wings are used for flying

Question 5

Divergent Evolution

-increasing structure diversity over time

Answer 5

Homologous

Question 6

Convergent Evolution

-independent evolution structures end up being similar

Answer 6

Analogous
