Viagra & Evolution

What are you talking about? People die premature deaths all the time for many different reasons, and the ones that survive to reproductive age do not all reproduce at the same rate, if at all. Evolution is alive and well, thank you.

We've been doing that for a long time. Sexual selection is one instance.

I stand by what I said. Evolution is alive and well, thank you. The fact that we have changed the enviroment to such an extent that old evolutionary pressures do not have the same impact that they used to have does not mean that evolution stops. New evolutionary trands will replace the old ones.

That's the most important point of your post. If everybody lives long lives and reproduce, we end up with a population explosion which cannot persist forever (The Earth is afterall finite). Something's got to give. Be patient, and you are bond to see evolution comming back with vengence.But you are right. Human evolution has stopped, but for a different reason

Define unfit. Does the fact that primates are unable to produce their own vitamine c make them unfit?

People with dawn syndrome don't reproduce. Many severe disabilities will also prevent reproduction. You didn't answer my question about the fact that you and me are not able to produce vitamine c. Are we unfit?

First of all, I didn't say that they are sterile. I said they don't reproduce, which is close enought to truth for the discussion here. Which is why I used the word 'many'. A vague statement desrves a vague response. You didn't answer the question either.
