Answer: A. Artificial selection
Explanation:
Artificial Selection, the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
According to the evolutionary theory, over the history of the human species, aggressive males have had the greatest impact on the gene pool. It is natural selection.
<h3>What is evolution?</h3>
The term evolution refers to descendence with modification, which mainly occurs due to natural selection.
Natural selection refers to the differential process of survival and reproduction of the fittest individuals in a population.
Aggressivity may thus represent an adaptive feature (i.e., an adaptive trait) in human evolution.

Blood flows to the brain through the internal carotid and vertebral arteries and away from the brain through the internal jugular vein. The internal carotid artery supplies the brain, while the external carotid nourishes other portions of the head, such as the face, skull, scalp and the meninges. The vertebral arteries provide supply to the upper spinal cord, brainstem, cerebellum, and the posterior part of the brain.
