Lyfe is concept defined by Stuart Bartlett, Michael Wong and others in an attempt to introduce a broader concept on the definition of living organisms. The term was coined to reserve life exclusively for life on Earth and lyfe for the generic phenomenon. The concept was also defined to avoid references to Earth-based life phenomena such as Darwinian evolution or cells. Lyfe is defined as a dissipative system capable of autocatalysis, homeostasis, and learning.

Dissipation
(a low entropy system)

Autocatalysis
(growth)

Homeostasis
(stabilization)

Learning
(acquire information to increase chances of survival, eg: evolution)
