In dark pools in Mexican caves, the blind cavefish survives just fine without eyesight, finding food in an environment of low productivity, swimming without bumping into the sides of the rock walls.
A team of University of Maryland researchers has recently found an important clue into how blindness might have evolved in these fish over the past 10,000 years. As reported in the Oct. 14 edition of the journal Nature, two genes with cartoon-like names--sonic hedgehog (shh) and tiggy winkle hedgehog (twhh) -- appear to play a major role in eye degeneration in the blind cavefish.
