Blind mole rats could be a real eye-opener for evolutionary science. Because they are completely blind, blind mole rats have been important laboratory animals in tests on how eyes and eye proteins function. Unfortunately for the lab mole-rats, this included surgically eliminating the eyes of a few of the research study topics (a procedure called enucleation). Most humans are not particularly fond of desert life, and thus do not tend to interact frequently with naked mole rats. Mole rats spend nearly all their lives underground, but they are not blind as was long thought, and are even color-sensitive, new research confirms.

Tests 1.5 years after the surgery validated, nevertheless, that these people’ daily behaviours were no various from the other captive mole-rats, consisting of digging, grooming each other, and play-fighting. They then recorded whether the mole rats used the peat to block the light. Yet this in no way is evidence of poor design. They are hugely found in the African states and can live in harsh environments. They are expert burrowers and amazingly can travel as fast backwards as they can forwards.
