Evolution means change.
I agree entirely. But put 100 people in a room and ask them if humans are the most evolved species on the planet 99 will say yes. While it is true that natural selection does not work for the good of the species, but rather the good of the individual. If you accept this then you are basically saying that humans will have been naturally selected to be selfish. Moral consciousness, on the other hand, is generally noble and unselfish.
