According to the common viewpoint, life is an open system that interacts with external energy. The mainstream viewpoint is that this causes a decrease in its entropy, enabling life to emerge on the first place and to sustain itself, thus avoiding chemical chaos. In return, the system releases entropy to its surroundings so that the 2nd law of thermodynamics is not violated. The common view that the origin of life is characterized by accumulation of order, as order means lower entropy. However, the term order can be very subjective, as an object non involved in life such as a rolling stone can say that it sees no order or no meaning in living systems’ chemical reactions. Just chaotic chemistry. So lets just leave order on the side and calculate entropy changes directly. Does the entropy in living systems actually increase or decrease? If it increases, is it doing so in a pattern that suggests an arbitrary system? Although I am not a physicist I will welcome suggestions on how to calculate changes in the entropy of life over time.
Here are some simple approaches: Forgive me for any mistakes…1)Does the life-associated heat production increase or decrease over time and how? Can life-associated changes in temperature be calculated?2)Since chemical systems with higher entropy are characterized by increased gas production, does a life-associated gas production increase over time? In a system of decreasing entropy, one would expect a declining life-associated gas production…Any ideas:?
