One can not imagine what it looks like a real picture of life as he can see less than 1% of the electromagnetic spectrum and hear no more than 1% of the acoustic. 90% of the cells in your body operate in symbiosis with microorganisms, which have their own DNA and are not "your". The atoms in your body are at 99% 9999999999999999 empty space, and none of them is begotten you - all borrowed from the former stellar matter, once emerged in the belly of the exploded star. Man has 46 chromosomes, 2 less than potatoes. Rainbow on a rainy day a man shows only itself: its existence due to the peculiarities of human vision and depends on the conical photoreceptors in your eyes - for other living beings, do not have similar cones, cones, rainbow does not exist. Thus, you do not just see a rainbow - you create it. It's pretty amazing, especially when you consider that all the beautiful colors that you see, are less than 1% of the electromagnetic spectrum.
