3.4 Evidence of Evolution

Question 1

1. Biogeography

Answer 1

Geographic patterns of species distribution

Question 2

2. Homologous Features

Answer 2

Structures with common evolutionary origin that may serve different functions in modern species.
ex. early embryos of invertebrates

Question 3

3. Analogous Features

Answer 3

Structures that perform the same function but not similar in origin or anatomical structure
ex. wings for flights

Question 4

4. Vestigial Features

Answer 4

Non-functioning or marginally functioning structure that is homologous to a fully functioning structure in a closely related species
ex. hip bones in whales, or goosebumps and hair in humans

Question 5

Name the four:

Answer 5

Biogeography, homologous features, analogous features, vestigial features.
