in a scientific sense it may not be evidence for evolution but it does not either disprove it or render it defunct so we now have to go and develop a new theory, which would keep all the evolutionary biologists busy for the next decade or so.On the subject of evolution however, humans do have very little in the way of natural adaptations, to defend against predators, we cannot leap from treee to trees or remain in trees to reduce the risk of predation as can smaller apes,......
Edit: I'm not a creationist whoever thumbed me down. But to clarify so that mistake isn't made, there is plenty of evidence for evolution based on what we have observed using the scientific method and until such a time as another theory has been developed, which likely won't be anytime soon it will remain the best theory we have for how organisms have developed over time. So no, in a scientific sense it may not be evidence for evolution but it does not either disprove it or render it defunct so we now have to go and develop a new theory, which would keep all the evolutionary biologists busy for the next decade or so.
On the subject of evolution however, humans do have very little in the way of natural adaptations, to defend against predators, we cannot leap from treee to trees or remain in trees to reduce the risk of predation as can smaller apes, orangutans and monkeys. Larger apes of course have their enormous size for protection and tend to aggregate making them less appealing to a would be predator.
Even in those climates,with conditions that seem relatively stable, even the slightest bit of change can make a huge difference to the living things: this is why global warming is such a concern. I dont think i've heard about a prokaryote living for hundreds of years- actually I've always known bacteria to have a relatively short life span (from 20 minutes to 48 hrs). I think its important to note that evolution is not about "survival" per se, its just as much about survival as it is about reproductive success (if not more so). The reason why bacteria have evolved despite their ability to survive well in various climates is because of the simple mutations that occur with each division (and there are many in very short periods of time).
I'm not sure if i understand your friend's last comment, but Intelligence is absolutely a product of evolution. If technology has enabled us to live longer, healthier lives, how is intellect not an advantageous quality for us to possess?
