These ecosystems supported numerous lives that survived the cold and harsh environments.The evidence to support the Thermal Vents theory is that they found ecosystems in the lowest parts of the ocean. Molecules are formed between the hydrothermal vents and the cold water. The data that supports this theory is that the ecosystems found supported the life of many organisms.
