Human evolution has ceased - for there to be natural selection, there must be survival of the fittest. Today, everyone survives, at least long enough to pass on their genes.
I posit that many of us have genes for selfish behavior; those genes made sense in the Stone Age. Maybe rape or genocide genes too.
Don't believe me? Answer this question: why are men 25% bigger than women, on average? Answer, because our ancestors competed for breeding possibilities, and the bigger men won out, even though there is a penalty for larger body mass.
Though the evolution of behavior traits has ceased, some believe the evolution of behavior ideas is still going on - memetics.
After consideration, I don't think *ideas* are strong enough to overcome our natural tendencies. If it were otherwise, there would be no religious wars.
Colonize the galaxy? Plausible, even if all we do is send our genetic material. Once started, a chain reaction completes the process in blink of an eye.
What should we do?
