A theory for the origin of life based on clay was forwarded by Dr. A. Graham caims-Sn\mith of the University of Glasgow in 1985 and adopted as a plausible illustration by just a handful of other scientists including Richard Dawkins. Clay theory postulates that complex organic molecules arose gradually on a pre-existing, non-organic replication platform made of silicate crystals in solution. Complexity in molecules developed as a function of selection pressures on types of clay crystals present. They then served as the replication of organic molecules independently of their silicate “launch stage”.
