In accordance with the Theory of Evolution, Natural Selection is mechanism through which the evolution happens. Advantageous traits survive the longest and leave the most offspring, a process termed as Natural Selection.
Select an animal species. Your goal is to explain the way where an evolutionary change might takes place for a particular characteristic (trait) of that species as a result of natural selection. The characteristic would be something such as coloration pattern, length of the limbs, or size of teeth or beak, or any measurable trait that is inherited.
The organism you select should be a real one however the evolutionary change you explian can be real or theoretical.
Assume a level area of granite rock was the parent material in both cases; describe in general terms how you would expect two soil profiles to differ, one in warm, semiarid grassland and the other in a cool, humid pine forest.
