OOOHH i love these great scientifical discusions

Ok so im on the bus for my science classes' field trip and im reading my book minding my own business. as the trip goes on i cant help but hear this discusion that is going on across the aisle.
Two of my class mates were in a deep disscussion about the relevance of genetic enhancement to the human race as a whole. for awhile i just listened but then as i heard him going around in circles i couldnt help but join in. now dont get me wrong, i dont see a problem with genetic enhancements that would enable us to be more resistant to viruses and diseases such as AIDs and cancer. But this guy was talking about a whole new "evolutionary step" for the human race. cause he hasnt seen any changes at all. i decided that use the theory of evolution as fact for this arugment so as not to de rail the discusion to something totally different. so i asked him how long it takes for a species to evolve. instead of answering my question he stated that he hasnt seen any changes at all in the human race since the egyptians. he said that we have evloved as far as we can in the physical aspect. but its our inteligence that has not made any progress. so he proposes to make our brain capacity larger than it already is. i then pointed out to him that we already dont use about 70 - 80 % of our brain capacity. which indicates to me that we are not lacking in the smarts. but the time to USE all the space, we dont live long enough. he said that if humans were smart that we would have already been in space and exploring. i asked him what he was comparing them to. givin that time period what other race has made it into space? he then dodged it and said that he wasnt just talking about making it into space.
the main point of his is that inteligence and the physical being were 2 totally differnent things. which from that statement it would make sense that one doesnt nessecarily rely on the other. well he thinks that by making our cranial capcity bigger we can become smarter. as if inteligence is passed on. you must learn stuff. but set that aside. i left that cause it wasnt part of what i was trying to argue. i was trying to make him understand that there are morals in all of this. but he only thought of it as a tool. but it was part of evolution. evolution happens naturaly not with tools. it also arises from the need to adapt to some situation or need to be more efficient with our current resources. i asked him a few times what our need to addapt was. if he had said build in inmunites to what i mentioned at the begining i wounldnt have minded to much. but his whole point was that he didnt like the fact that human race hasnt changed much made him mad. it came down to it that he is on the evyromental bandwagon about us ruining our atmosphere and that humans would have to adapt to the changes quickly. so he is totally into pop culture or would that be cult culture? i dont know, either way its total crap. as i listened to him talk after the discussion it became apparent to me that he never knew what he was talking about. at the point that i knew he was a tree hugging loser, i just sat and listend to him. he was proposing that we splice the genetic qualities from star fish that let them regenerate their legs into humans so that we can heal faster and grow extra organs. that idea sounds like something that would come out of a 10 yr olds mouth that is totally into the X-Men.
I win.
