Are you talking about purely biological (i.e. genetic) evolution or cultural as well?

We continue to develop new tools and technologies. So evolution has not halted on the cultural level, nor will it for the forseeable future.

I also find it hard to understand (maybe the scientists can enlighten me) how any species could stop evolving (short of it being extinguished completely). People still make choices about when and how much to breed. Some segments of the population have more offspring than others. Diseases still kill off more people with less immunities to them. All of these ensure that the next generation is different than the last and that humans keep changing.

Our cultural and socio-economic systems (environment) still favour certain traits, don't they?
