Well said davidelkins. The theory of evolution states the human reproductive system receives radiation from the surrounding environment (including the Sun) causing mutations. If this mutation is advantageous enough to allow the creature to reproduce, that mutation is inherited and life lives. I believe not in a theory of evolution, but what I do find remarkable is the survival of ALL creatures. We're still going! Is it love that drives creatures to continue the survival of the species, or just animal instinct??
