Most cave dwellers have eyes or vestiges of eyes, but if removed from the cave into lighted areas, still cannot see. Are there any studies which have been done to demonstrate that this blindness is genetic, and that if a newborn of the cave species were raised in a lighted environment, it would still remain blind? Also, have any tests been done to see if they can produce viable offspring with their light-dwelling counterparts? ie, can cave crickets mate with regular crickets or grasshoppers and have young that are fertile?
