The Temporalities of Life

Life on Earth is an historical phenomenon; ori­ginally, there was no life; now life exists; in the future, life will vanish. However, it would be misleading to consider the existence of life on Earth as a unified process. Life is a plurality, and the stabilisation and continuity of key processes have given structure to the evolution of life. From the perspective of physics, time is simultaneity made real by a material signal. Simultanei­ty is essential for the temporality of life as well, and the key issue is synchronization of different cyclic processes of renewal and reproduction in the physiology of single organisms, and through interactions between different organisms. As the characteristic time-scales of key processes vary, life exists in many temporalities.
