Great illustration of the tenacity of life through a simple observation. In Jurassic Park, the dinos are genetically programmed to be deficient in lysine, an essential amino acid, so that they cannot reproduce. But towards the end of the movie, eggs are found under a tree: "life has found a way". None of these examples, however, show that life is not fragile. Individual life is fragile as well as impermanent. It is only if we consider life as a whole in terms of a species, or all living organisms, that it acquires a 'non-fragile' character.
