An example of natural selection is the tail of a male peacock. The females of the species choose mates based on the colors of th
e males’ tail feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the tails of peacocks over time?
Since the means of reproduction have changed, the population of peacocks would probably start losing their pretty feather colors due to the fact that over time females would be mating with the containing the other trait (and possibly not the pretty feathers). This would then produce offspring with ugly colors but also with the desired trait. This would continue on and on until those with the desired trait outnumbered or possibly extinguished the now unnecessary vibrant feather colors.
The crust must have continental (granitic) plate and oceanic (basaltic) plate to cause both explosive (granitic magma) and non-explosive (basaltic magma) eruptions.

<span>The pancreas functions in the digestive system by producing many digesting enzymes. The cells of the pancreas must have lots of rough ER to meet this demand.</span>
