EVOLUTIONARY ECOLOGY

Question 1

one organism interacts with another or the environment

Answer 1

lowest level

Question 2

interaction may occur between large groups of organisms or different species

Answer 2

largest level

Question 3

organisms of the same species

Answer 3

population

Question 4

modification, alteration, transformation, alteration, variation, adjustment

Answer 4

change

Question 5

differential survival and reproduction among individuals of a population

Answer 5

natural selection

Question 6

the fact that all living organisms share the same set of characteristics

Answer 6

unity

Question 7

any feature that enables an organism to increase its ability to survive and reproduce

Answer 7

adaptation

Question 8

characterized by changes to the genetic composition of a population

Answer 8

evolution

Question 9

2 step process of evolution

Answer 9

genetic variation
natural selection

Question 10

processes that cause genetic change

Answer 10

genetic variation

Question 11

selection of those individuals that will survive and reproduce successfully

Answer 11

natural selection

Question 12

potent evolutionary source that creates new sequences of base in the DNA and creates new genetic info

Answer 12

mutation

Question 13

raw material from which patterns of change emerge in populations; not all changes happen at phenotype level

Answer 13

variation

Question 14

movement of alleles between different population

Answer 14

gene flow

Question 15

can shape the genetic composition of a population; nonselective force of evolution

Answer 15

chance

Question 16

a population that can breed to produce offspring that can then produce offspring themselves

Answer 16

species

Question 17

tracing the family tree

Answer 17

genealogy

Question 18

evolutionary history of a species or a group of species

Answer 18

phylogeny

Question 19

quantifiable, heritable trait such as the number is segments in a backbone

Answer 19

character

Question 20

character present in a group but not in any of the group’s ancestor

Answer 20

derived trait

Question 21

group whose members share one or more defining derived traits

Answer 21

clade

Question 22

consists of an ancestor together with any and all of its descendants

Answer 22

monophyletic group

Question 23

making hypotheses about evolutionary relationships among clades

Answer 23

cladistics

Question 24

result of cladistic analysis

Answer 24

cladistics

Question 25

a diagram of evolutionary connection; visually summarizes a hypothesis about how a group of clades are related

Answer 25

cladogram

Question 26

represent a common ancestor of two lineages

Answer 26

node

Question 27

two lineages that emerge from a node on a cladogram

Answer 27

sister groups
