New Species Discovered in an Israel Underground Cave.

While digging in a rock quarry, a team of the Hebrew University of Jerusalem scientists discovered a massive 2.5 kilometer long and 100 meters deep cave, since dubbed the "Ayalon cave", complete with an underground lake.

In this cave, scientists already discovered 8 new species, who evolved in complete isolation from the outside world, perhaps for millions of years.
