The four factors that affect evolution are mutations, natural selection, genetic drift and the gene flow, In the case, if the ground finches that Grants studied, we can observe the working of the natural selection. Due to change in the conditions in the environment, the large beak was an advantageous trait that was favored by the natural selection. The result of this process was an increase in numbers of large beaked finches and decrease in small-beaked finches compared to the initial numbers in the population.

Explanation:
Phytoanticipins are defined as defense compounds which are constitutively present, i.e., regardless of the presence of pests or diseases.
<em>They are exothermic as they take temperature from the surrounding and then maintain their internal body temperature according to the amount of heat absorbed :)</em>
