    This is not evolution.

    It is just adaptation.

    Big difference.

    Nope

    As the bigger tusk elephants have been hunted.

    The smaller tusk elephants had more chance of survival.

    Thus the gene pool tended to be skewed towards smaller and smaller tusked animals.

    This is not in any way evolution.

    But a direct result of man made hunting practices. :doubt:

    Weeding out certain traits from the gene pool isn't really "evolving". It is not producing a new trait that was never present before, it's just making a rare trait much more prevalent.

    Actually any factor that drives a species gene pool in a certain direction can be considered part of the evolution of that species, whether or not that factor is natural or created by mankind. "Skewing" the "gene pool" by killing off specific parts of it is evolution. Evolution refers to the changes in form, function and genetics that happens as a result of environmental pressures that favor one genetic development path and suppress other paths. The domestication of dogs from the original wolf genetic pattern is an example of a man caused "evolution" of a species into very different physical forms and basic psychology.

    Isn't learning a new trait evolving in to something else? Same with adaptation. Evolve could mean any "new" thing that is not the "norm". Right?

    Yes, it is. It's the survival of the fittest. That is the foundation of natural selection, one of the processes that drive evolution.

    If it's an instinctual and inherited skill, as opposed to a learned behavior, you can argue that, but that's still debatable.
