Perceiving "Complex Autonomous Systems" in Symmetry Dynamics: Elementary Coordination Embedding in Circadian Cycles.

This study explored the biological autonomy and control of function in circumstances that assessed the presumed relationship of an organism with an environmental cycle. An understanding of this behavior appeals to the organism-environment system rather than just the organism. Therefore, we sought to uncover the laws underlying end-directed capabilities by measuring biological characteristics (motor synchrony) in an environmental cycle (circadian temperature). We found that the typical elementary coordination (bimanual) stability measure varied significantly as a function of the day-night temperature cycle. While circadian effects under artificially manipulated temperatures were not straightforward during the day-night temperature cycle, the circadian effect divided by the ordinary circadian rhythm remained constant during the day-night cycle. Our observation of this direct, robust relationship between the biological characteristics (body temperature and motor synchrony) and environmental processes (circadian temperature cycle) could mirror the adaptation of our biological system to the environment.
