Study Reveals How a Tiny Cavefish May Help Humans Evolve to Require Very Little Sleep (IMAGE)
Caption
The Pachón cavefish live in deep, dark caves in central Mexico, with little food, oxygen or light, and have lost their eyes completely. Because of their harsh environment, they have evolved to get very creative in order to survive and suppress sleep. They are able to find their way around by means of their lateral lines, which are highly sensitive to fluctuating water pressure.
