Evidence of Evolution

Question 1

focuses on studying the differences and similarities between the anatomy of organisms

Answer 1

COMPARATIVE ANATOMY

Question 2

different traces or remains of an organism change over time by natural processes.

Answer 2

FOSSIL RECORD

Question 3

Bones of dead organisms used to trace ancestors and evolution

Answer 3

FOSSILS

Question 4

Species variation occurs through mutations and several reproduction, but humans select features that are beneficial

Answer 4

ARTIFICIAL SELECTION

Question 5

Organisms from prior geographic regions that were closely related but different species traveled into surrounding habitats and evolved in these far apart geographic regions.

Answer 5

GEOGRAPHIC DISTRIBUTION

Question 6

Different species evolve to have similar traits due to a similar environment

Answer 6

CONVERGENT EVOLUTION

Question 7

Same species evolve to have different characteristics due to variation in the environment.

Answer 7

DIVERGENT EVOLUTION

Question 8

Parts similar in structure but have different functions depending on the animal.

Answer 8

HOMOLOGOUS STRUCTURE

Question 9

Structures that have similar functions even though they have developed independently between different organisms.

Answer 9

ANALOGOUS STRUCTURE

Question 10

All living things share the same genetic structure but to varying percentages

Answer 10

MOLECULAR HOMOLOGIES

Question 11

made up of nucleotide sequences that dictate the information that is contained in the molecule.

Answer 11

DEOXYRIBONUCLEIC ACID (DNA)

Question 12

Embryos of vertebrates develop in the same way and have similarities in the earlier stages such as the tail and pharyngeal pouches which become ears for humans but gills for fish.

Answer 12

EMBRYOLOGY

Question 13

structures that have lost their function over the course of an organism’s evolutionary history.

Answer 13

VESTIGIAL STRUCTURE
