Regarding the question of cognition, the authors review work showing the cognitive behavior of bacteria. And natural selection, they assert, is in effect "just the biological term for kinetic selection." The beginnings of autonomous behavior, at the heart of autopoiesis, can be found in chemistry. This comes from the Greek works for self ( auto) and creation or production ( poiesis).īy signing up you agree to receive email newsletters or alerts Current Science Daily. The article reviews recent research on replicative processes in biology and chemistry and find it merges with established biological thinking in the concept known as autopoiesis. But once such a chemical system becomes replicative, the conceptual gap separating chemistry and biology begins to narrow. The DKS state is a recently discovered non-equilibrium state, which crucially depends on a continual supply of energy and other inputs from the environment. The authors highlight the more recent concepts of dynamic kinetic stability (DKS) and dynamic kinetic chemistry, the chemistry of systems in that DKS state. In other words, Pascal and Pross say, "it took place along both physical and mental axes, both facets would necessarily have been present from the beginning of the evolutionary process." They start with Charles Darwin's theory of evolution, which involved both "corporeal and mental endowments," as Darwin put it. The authors give a good sense of how science advances, and where their own views are grounded. Their research has long focused on basic aspects of the origin of life problem.Īddy Pross is an emeritus professor in the department of chemistry at Ben Gurion University of the Negev in Israel.įor a lay reader, the article usefully reviews the scientific development of ideas about life's special properties, going back to the late 19th Century, and describes the conceptual and research advances of the scientists involved. Addy Pross, the lead author, is an emeritus professor in the department of chemistry at Ben Gurion University of the Negev in Israel. Robert Pascal is an emeritus professor of chemistry at Aix-Marseille University in France. If life emerged from non-life, as many scientists hold, how did this dead matter begin to think?
