1) what factor determines whether a trait is beneficial of harmful?


2) why do organisms face a constant struggle for existence?

3) where did the founder come from that lead to the 12 species of finch found on the galapgos lslands today?


4) in what way did darwin finches most notably differ from one another?



5) what environmental factor drove the natural selection that occurred in darwin finches?


6) what is the name of the type of evolution that causes related organisms to become less alike?



7)what does the geographic isolation of two populations of a species tend to increase difference between their gene pool?



8) what is the name of the type of evoulution that causes distantly related organisms to become more alike?



9) what is the name of the hypothesis that states that evoultion occurs at a slow constant rate through geologic time?


10) list an environmental factor that could trigger MASS EXTINCTION


11) what does there tend to be rapid evolution among the species that survive a mass extinction?


12) give example of analogous structures




13) give an example of homologous structures?

You are supposed to ask **A** question, not 13. You could have at least divided them up into 4 or 5 different posts.



1) what factor determines whether a trait is beneficial of harmful?
the organisms' current environment

2) why do organisms face a constant struggle for existence?
because of limited resources and because more individuals are born than can possibly survive.

3) where did the founder come from that lead to the 12 species of finch found on the galapgos lslands today?
The mainland - northwestern South America

4) in what way did darwin finches most notably differ from one another?
beak size and shape

5) what environmental factor drove the natural selection that occurred in darwin finches?
