It came into existence because the chemistry of life on this planet allows for it, through multiple different pathways, and nothing prevents it. If an organism contains any number of photo-reactive chemicals or structures, they can, for example, absorb a proton and shed an electron. A mutation that affects one of these structures or chemicals can variously confer or remove this ability from that organism - as has demonstrably happened in both directions. For example, the process used by plants comes from symbiosis between a protist and bacteria. Since that time, most of those bacteria lost the ability to photosynthesize...and then, apparently through lateral transfer, regained it.
Amazing, eh?
but if 'the chemistry for life on this planet allows for it and nothing prevents it' and thats the reason why it happens then why dont humans use photosynthesis also ? we live on the same planet with the same chemistry . and what do you think started this process to begin with ?
