The Seven Pillars of Life are the essential principles of life described by Daniel E. Koshland in 2002 in order to create a universal definition of life. One stated goal of this universal definition is to aid in understanding and identifying artificial and extraterrestrial life.
The seven pillars are Program, Improvisation, Compartmentalization, Energy, Regeneration, Adaptability, and Seclusion. These can be abbreviated as PICERAS.
Seclusion is the separation of chemical pathways and the specificity of the effect of molecules, so that processes can function separately within the living system. In organisms on Earth, proteins aid in seclusion because of their individualized structure that are specific for their function, so that they can efficiently act without affecting separate functions. |
