I recently read this article that one guy here on the forum wrote few years ago: "Evolution knows nothing. It has no direction or knowledge about anything. Natural Selection drives which random mutations in the genetics of a population are left to be passed on to the next generation. If a change in genetics favors one individual, that individual is more successful at reproduction. Over many generations the traits that confer success become more common." The rest of the conversation betweene useres was that nothing directs evolution. That there is only random variaton plus reproduction that is important. This word RANDOM variation is what bothers me Why then does camel in desert dont lose time on growing wings? Why does a bear in the woods never had wings? At least one bear. Why dont bird develop water supplies? Because they dont have to. And how do animals DNA know what would benefit them? It gets feedback from senses. I go a little bit in the extreme but you get my point. It seems to me that the body when comes to new enviorment in order to survive looks inside its resources to find the way tu survive. If there is no one, DNA starts the slow change.. To cold? To hot? Nothing to eat? Hard visibility? Let give this animal what it needs. What do you think? Does this have any sesne to you? Is it change in the DNA major triggered by our senses? Does the DNA give us and develop for us just what we need?
