evo with co-evo

Question 1

individuals vary & these are heritable, populations reproduce excessively, selective pressure exists, the fittest survive and reproduce

Answer 1

4 steps of natural selection

Question 2

change in population traits over time

Answer 2

evolution

Question 3

the evolutionary process where a new species is formed from an existing one

Answer 3

speciation

Question 4

bacteria evolving resistance to antibiotics

Answer 4

modern example of microevolution

Question 5

relationship of hummingbird to long tube flowers, beak evolves to reach nectar

Answer 5

example of co-evolution

Question 6

can lead to specialized relationship between species (parasite & host, plant & pollinator, predator & prey)

Answer 6

benefits of co-evo to species

Question 7

evolution of specific species

Answer 7

micro evolution

Question 8

evolution of species as a whole

Answer 8

macro evolution

Question 9

rate of speciation

Answer 9

slow

Question 10

rate of mutation

Answer 10

slow, due to radiation and reproduction

Question 11

very low number of only hard bodied specimen

Answer 11

fossilization

Question 12

the place or set of environmental conditions in which a particular organism lives

Answer 12

habitat

Question 13

role played by a species in a biological community, set of environmental factors that determine distribution

Answer 13

ecological niche

Question 14

states that no two species can occupy the same ecological niche at the same time

Answer 14

competitive exclusion principle

Question 15

species co-exist in a habitat by utilizing different parts of a single resource

Answer 15

resource partitioning

Question 16

two or more species live intimately together with their fates linked

Answer 16

symbiosis

Question 17

both organisms benefit from their association

Answer 17

mutualism

Question 18

one species benefits while the other neither benefits nor is harmed

Answer 18

commensalism

Question 19

a form of predation, is also sometimes considered a symbiosis bc of the dependency of the parasite on its host

Answer 19

parasitism

Question 20

over time predator and prey evolve in response to one another

Answer 20

coevolution

Question 21

harmless species mimic the warning coloration of harmful species to gain protection

Answer 21

Batesian mimicry

Question 22

two harmful species evolve to look alike

Answer 22

Mullerian mimicry

Question 23

change in population characteristics over generations

Answer 23

evolution

Question 24

these populations changed from a common ancestor

Answer 24

theory of common descent

Question 25

populations have changed over time into the different species we see today and theory of common descent

Answer 25

central tenets of evolution

Question 26

formation of new species

Answer 26

speciation

Question 27

interbreed to produce fertile offspring in nature

Answer 27

biological species concept (BSC)

Question 28

Where does variation come from?

Answer 28

random mutation
