In 1986 a group of Romanian scientists working near the Black Sea stumbled upon one of the most amazing discoveries of this century, one that would revolutionize our understanding of what life is and where it came from. Geologist and cave explorer, Christian Lascu, was inspecting a series of six test wells at a site where the government was planning on building a power station, the first five bore holes yielded nothing unusual and the sixth looked equally unpromising at first. The workers were inside and said they found a small hole. The geologist dug and realized there was a cave there. His task was to explore the well and insure that the limestone bedrock would support the foundations of the power station. The strong sulphurous smell at the bottom drew him on into the unknown, he reached a small sulforous lake and saw many small animals. He knew immediately this cavern was unique, where had these bizarre animals come from and how could they survive in this hostile environment deep underground?
