Cavefish
Borowsky and his assistants descended into the caves and fished out
different blind populations to cross in the lab. If the fish had the
same developmental mutations, the researchers reckoned they would
produce blind offspring. Instead, the experiment produced a number of
fry with functioning eyes; in the most successful pairing, 40% of hybrid
fry could see. The results suggest fish from different caves have
mutations that don't overlap.
