| Hypothetical types of biochemistry hypothetical types of biochemistry are the different types of speculative biochemistries of alien life forms that differ radically from those known on Earth. It includes biochemistries that use elements other than carbon to construct primary cellular structures and/or use solvents besides water.Theories about extraterrestrial life based on these "alternative" biochemistries are common in science fiction.

| Neural Darwinism Neural Darwinism, a large scale theory of brain function by Gerald Edelman, was initially published in 1978, in a book called The Mindful Brain (MIT Press). It was extended and published in the 1989 book Neural Darwinism - The Theory of Neuronal Group Selection.Edelman won the Nobel Prize in 1972 for his work in immunology showing how the population of lymphocytes capable of binding to a foreign antigen is increased by differential clonal multiplication following antigen discovery.
