Question 10

name all three things that make natural selection seen as a comsequemce of …

Answer 10

heritable variation, excess production, and differential success

Question 11

over time what is natural selection a result of ?

Answer 11

results in adaptation (adaptive evolution) when organism set in there environment

Question 12

what is heritable variation

Answer 12

individuals in a population are born differing in many traits, many traits can be passed from parent to offspring

Question 13

what is excess production

Answer 13

any population, more offspring are produced than needed to maintain it, where the resources are limited causing offspring to fail

Question 14

what is Differential succes

Answer 14

because of differing traits some individual are more likely to surive and reproduce, this is what fitness is

Question 15

darwin found that…

Answer 15

Artificial selection on heritable variation exists species show sign of natural selection
