lifestyle choices

Question 14

theory stating that natural variation among organisms that make them the best adapted to their environment, live and reproduce better. “survival of the fittest”

Answer 14

Natural selection

Question 15

Change in a kind of organism over time; process by which modern organisms have descended from ancient organisms

evolution

Question 16

range of differences in DNA among organisms

Answer 16

genetic variation

a trait that helps an organism survive and reproduce

Answer 17

adaptation

Question 18

What are genes?

Answer 18

the basic unit of heredity passed from parent to child

Question 19

What do genes do?

Answer 19

contain the information needed to specify physical and biological traits

Question 20

Who is Charles Darwin/ what is he known for?

Answer 20

the founder of the theory about evolution by natural selection

Question 21

Where did Charles Darwin travel to

Answer 21

The Galapagos Islands

Question 22

What causes genetic factors?

Answer 22

changes due to issues within the DNA

Question 23

Anatomy, Molecular biology, biogeography, fossils, and direct observation are all evidence of what?

Answer 23

Evolution

Question 24

species may share physical features because the feature was present in a common ancestor

Answer 24

Anatomy

Question 25

DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are

Answer 25

Molecular biology

Question 26

The global distribution of organisms and the unique features of island species reflect evolution and geological change

Answer 26

Biogeography

Question 27

document the existence of now-extinct past species that are related to present-day species

Answer 27

Fossilis

Question 28

We can directly observe small-scale evolution in organisms with short life cycles

Answer 28

Direct observation

Question 29

How is natural selection and artificial selection related?

Answer 29

They both have to do with the best of a species surviving
