Bio. Evolution-Eh

Front 1

Three things that convinced Darwin that evolution occurs

Back 1

Variation of similar species among islands, fossil evidence, geologic events

Front 2

process by which humans change a species by breeding

Back 2

artificial selection

Front 3

in order for natural selection to occur the trait must be ___

Back 3

heritability

Front 4

differences in physical traits of an individual from the group to which is belongs

Back 4

Variation

Front 5

In artificial selection ___(1)___ acts as the selecting agent whereas in natural selection, ____(2)____ determines if the trait is passed on or not

Back 5

1. genetic variation
2. enviroment

Front 6

individuals that have inherited beneficial adaptations/produce more offspring on average than do other individuals in the same species

Back 6

natural selection

Front 7

all individuals of a species that live in an area

Back 7

population

Front 8

(over time) natural selection-results in sepcies that live in an area

Back 8

Descent with Modification

Front 9

year Darwin published his book on his ideas about evolution

Back 9

1859

Front 10

1. variation
2. overpopulation
3. adaptation
4. descent w/ modification

Back 10

4 main principles to the theory of natural selection

Front 11

body part that's similar in function as a body part of another organism but is structurally different

Back 11

Analogous Structure

Front 12

study of fossils or extinct organisms

Back 12

paleontology

Front 13

study of distribution of organisms around the world

Back 13

biogeography

Front 14

change in a species over time; process of biological change by which descendants come to differ from their ancestors

Back 14

evolution

Front 15

inherited trait that's selected for over time b/c it allows organisms to better survive in their enviroment

Back 15

adaptation

Front 16

theory that states that the geologic processes that shape Earth are uniform through time

Back 16

uniformitarianism

Front 17

process by which humans modify a species by breeding it for certain traits

Back 17

artificial selection

Front 18

theory that states that natural disasters such as floods and volcanic eruptions shpaed earth's landforms and caused extinction of some species

Back 18

catastophism

Front 19

remnants of an organ or structure that functioned in an earlier ancestor

Back 19

vestigial structure

Front 20

body part that is similar in structure on different organisms but performs different functions

Back 20

Homologous structure
