According to James Lovelock, to find signs of life, one must look for a “reduction or a reversal of entropy.” I’d look for an entropy reduction, since this must be a general characteristic of life.

Thanks for the invitation, a quote I like to refer to these days;

The general struggle for existence of animate beings is not a struggle for raw materials – these, for organisms, are air, water and soil, all abundantly available – nor for energy which exists in plenty in any body in the form of heat, but a struggle for [negative] entropy, which becomes available through the transition of energy from the hot sun to the cold earth.
Austrian physicist Ludwig Boltzmann.
