|
What is the biological meaning of " evolution"?
|
any genetic change in populations over time
|
|
|
|
Can an individual evolve?
|
No
|

|
|
How is natural selection different than evolution?
|
Natural Selection: Individuals
1. Individuals of species vary 2. vanation is heritable 3.more individuals born than can surviv 4. some vanations survive better than others |
Evolution: Species in Population over time
|
|
|
What are the four basic tenets of natural selection?
|
1. Individual and species vary
2. vanation is heritable |
3. more individuals born than can survive
4. some vanations survive better than others |
|
|
What is directional selection and what impact does it have on a population?
|
shifts the overall makeup of pop. by favoring varients of extream
favors only end of the curve disturbed habitats ( new conditions) |
|

|
what are the key attributes of natural selection, artificial selection, kin selection, and sexual selection?
|
Natural selection- what darwin meant
different survivals/ reproduction of individuals in nature Artificial selection: same as natural selection but humans control traits selected for or against domestic plants and animals |
Kin Selection:
selecting for genes not individuals helping a relative can result in more copies of your genes in next generation Same result as reproducing yourself / alarm calling Sexual Selection: competition b/w individuals of 1 sex for mating access to the sex 1. competiton for mates 2. matechoice many favor traits of reproductive success but reduce survival |

what is stabalizing selection and what impact does it have on a population?
|
culls extrcam vanants from pop eliminating individuals that are light or dark.
Favors average phenotypes stable enviorments |

|
what is diversitying selection and what impact does it have on a population?
|
favors vanants of opposite extreams over intermediate
favors bothe end of curve unusual occurs when different individuals exposed to different enviorments |
