Answer:
I'm thinking maybe B, illustrates the principle of natural selection.
Explanation:
This example shows that, once a particular event happens in a species' ecosystem that negatively affects their lifestyle, natural selection occurs and kills off those with a disadvantageous adaptation (in this case the narrow-beaked finches, since they could no longer eat insects but did not have the beak size to crack seeds), allowing those with the advantageous adaptation (in this case, the thicker-beaked birds) to prosper.
Functionalism. It is according to the concept 'survival of the fittest'
Heterozygous straight (F) x heterozygous bent (f)
________
<u>|FF | Ff |</u>
<u>|Ff | ff |</u>
That means 1/4 will be 100% straight
2/4 will have straight with a recessive trait of bent
1/4 will be recessive recessive which means bent
So out of 4 chimpanzees, 1 of them will have bent.
Hope this is what you wanted help with. :)
