Certain species of blind fish living in perpetual darkness in the ocean depths have evolved from ancestors that could see. Research indicates that the brain centers for vision in these fish is degenerating, whereas the brain conters controlling other senses are enlarging What might be the MOST probable reason for the loss of vision in these fish?
(1 point)
progressive selection of genetic variants in the population reading to blindness as an evolutionary adaptation
Infection by cave-dwelling microorganisms that nas ied to degeneration of the eyes
extreme high pressure at the ocean depths causing a detenoration of vision
exposure to mutagens that caused the loss of vision
