A cavefish-lives in total darkness, yet it has eyes. Which statement below
correctly states how this condition could change in the future and why?
A. Because the eyes might eventually be useful if the fish's
environment suddenly changed, the eyes will continue to be
present.
B. Because the genes that make the eyes are part of the genetic
code, the eyes will never disappear completely.
C. Because the fish does not use its eyes, they will eventually
disappear.
D. Because the eyes add nothing to the fish's fitness, it is possible
that they will disappear.



Answer :

Final answer:

Eyes in organisms, including fish in dark habitats, are influenced by their adaptation to the environment through evolutionary processes.


Explanation:

The eyes of organisms, including fish like cavefish, are evolutionarily shaped by their environmental needs.

While vestigial structures like eyes in dark habitats may eventually disappear if they don't impact fitness, the presence or absence of eyes is ultimately dictated by their adaptation to the environment and their role in the organism's survival.

Evolutionary processes play a crucial role in determining the presence and characteristics of sensory organs like eyes, reflecting the ongoing adaptation of species to their surroundings.
