Answer: lower atmospheric pressure
Explanation:
During the inspiration process the diaphragm, and external intercostal muscles. The contraction of the diaphragm causes the increase in the size of the thoracic cavity this causes the contraction of the external intercostal muscles. As a result of this the ribs and the sternum get elevated.
This causes the lungs to expand, and increasing the volume of the air passage. In this response the air pressure inside the lungs reduces below the air outside the body. Thus this facilitates the movement of the gases from a region of high pressure to low pressure, this way the air rushes into the lungs.

"Not all members of a species are the same. Every species exhibits variations in different traits like eye color, that are passed from parent to offspring."
This statement is paraphrased from the Darwins's theory. Darwin's theory suggested that there are variations among individuals in a population and that these variations will help individuals to survive. Natural selection is the differences in survival and reproduction as the consequence of differences in phenotypes.
