Why have living things always wanted to create new generations since the first? What drives them to create new generations and continue the next? For example,what we call motherhood instinct is actually an effect of the hormone lth, prl, you know, can not be limited to the effects of such hormones, right?
Vitality, by definition, is a structure that includes the phenomenon of reproduction. If something cannot produce its own copies, it is not alive. The only condition for vitality is not being able to reproduce; but being able to breed is one of the conditions of being alive. Therefore, the concepts of "vitality" and "non-reproductive being" are mutually exclusive.
Yes, perhaps under the conditions of another universe, under the laws of physics, chemistry, and biology, they could have evolved "living things." However, when we look at the evolutionary history in the part of the Universe we know, and especially on Earth, we see that the concepts of reproduction and vitality are intertwined.
