Ayalon: Natural Biosphere

In May 2006, a bulldozer working in the Nesher cement quarry on the outskirts of Ramla accidentally broke into the subterranean cavern.  

A cave was discovered in Ramla which sustains a most seldom type of ecosystem, based on bacteria that create all the energy they need chemically, from the sulfur compounds they find in the water, with no light or organic food coming in from the surface.

The finds have been attributed to the cave's isolation, which led to the evolution of a whole food chain of specially developed organisms, including several previously unknown species of invertebrates.
