Homeostasis Living organisms are self-replicating and self-sustaining dynamic chemical systems. They obtain energy from, and information about, their environment – including its chemical, physical, geological, and biological components. A feature that distinguishes living from non-living matter was identified by Claude Bernard. This is homeostasis – the maintenance of a constant internal environment despite changes in the external environment. A second feature of all known life, first proposed explicitly by Schleiden and Schwann, is that living things are composed of spatial compartments, called cells. Cellular homeostasis requires a system of integrated feedback and feedforward, producing adaptive responses to, and anticipation of, ultimately uncontrollable changes in the properties of the outside world. As life evolves, it extends its reach by maintaining its constant internal environment in new external environments, previously inhospitable... http://journalofcosmology.com/Abiogenesis118.html
