How did the chemicals for life come together??..

[Anomalocaris]

Did that argument come from a creationist? Hydrothermal vents are in the deep sea and is surrounded by very cold water. Therefore there is a steady gradient of temperatures in the vent cone itself ranging from boiling point under high pressure near the inner conduit wall, to near ambient temperature at the outside surface. The same applies the seawater surrounding plume of hot water after it comes out of vent opening. Therefore near the hydrothermal vents there can be found the degree of warmth to suite every biochemical taste. Furthermore, the particular type of vent in question comes in clusters, and each vent in the cluster is highly stable. Individual vent cones remain active for hundred to thousands of years before the conduit becomes clogged. So not only does the vent provide the conditions and materials for abiogenesis, it also provide the stability to allow abiogenesis to go through its steps.
