Question

The albino cavefish lives deep inside of caves where very little light ever reaches. This species is blind, and its skin actually has grown over where its eyes should be.

Knowing that they developed from ancestors that could see, which of the these would best help explain why the albino cavefish is now blind?

A) Botany
B) Evolution
C) Microbiology
D) Mycology

I don't know C or B?

Answer 1

B) Evolution would best help explain why the albino cavefish is now blind. Evolutionary processes and environmental pressures likely led to the loss of sight in this species over time, as vision became less critical for survival in the dark cave environment.

Answer 2

The best explanation for why the albino cavefish is now blind is option B) Evolution. Evolution is the process by which species change and adapt over time in response to their environment. In the case of the albino cavefish, living in the dark caves where very little light is present led to the loss of their vision over generations. Genetic mutations that caused the regression of their eyes were favored by natural selection since vision was no longer a necessary trait in their light-deprived environment. Therefore, over time, the cavefish evolved to be blind.
