evolution is blind because all of it is an accident. life forms that survive long enough to make more life forms get their genes to live on. any life form that doesn’t, well, doesn’t. better survivability because of an error in copying genes? more offspring. worse survivability? less offspring

there is no intention to evolution, it’s simply a consequence of the fact that some primitive life forms at some point felt a desire to copy their genes and the process of doing so is imperfect. That desire, probably a product of random copying itself, is what made all living things today
