Detailed explanation-1: -The Clay theory is an theory that the origin of life started with clay crystals replicating themselves with other biological molecules to help create organic life. The theory came from the book, Seven Clues to the Origin of Life written by the scientist, Alexander Graham Cairns-Smith.

Detailed explanation-2: -A theory that is based on the fact that growing crystals are able to pass on traits to new crystal generations, and that clay crystals may have acted as precursors to genetic genetic material.

Detailed explanation-3: -Clay Breeding Ground Research at the University of Glasgow, in Scotland, has given rise to the theory that life on Earth may have evolved in clay. It is suggested that clay may have served as an area of concentrated chemical activity, providing a breeding ground for DNA and other components.

Detailed explanation-4: -The community clay theory suggests that the original molecules of life formed within clay. It suggests that clay that, as it crystallizes, sticks together, is capable of bringing in more clay (because clay will stick to it)–and thus start a mechanism for selecting replicating materials.

Detailed explanation-5: -Graham Cairns-Smith of the University of Glasgow in Scotland, who first proposed the clay-life hypothesis in the 1960’s, said: ‘’It’s another talent that the clay has.
