example of "Evidence for evolution of the human population by natural selection..."?

I need this for a biology test. I was going to say the black death (plague, huge natural selection event), but this seems that its only microevolution. I m sure the question for my test is macroevolution, correct me if I m wrong.

Does anyone have a good example

    Depends on what you have as a definition for "evolution". If it's change of allele frequency of a population over time... which is the current definition, than the balanced polymorphism of sickle-cell anemia is a good example.

    Also unclear what you mean by "human population". That to me does not include speciation.

    If you're happy to accept microevolution, a change in allele frequency in a population over time, then sickle cell anemia or adult lactose tolerance could be used.
