Is there a kind of biological evolution neither macro nor micro?

Please give example with explanation.

Thanks.

    My population biology professor called it "intermediate evolution" and the examples he used were wolves -> dogs and teosinte -> corn. These are evolutionary changes in other species that took place over a period of time long enough to require generations of humans to observe them. It's basically more than just a change in allele frequencies, but less than the full "goo to you" scenario.

    Note that I've never heard anyone else use this term. You should just forget it.

    This categorical viewpoint on evolution grinds the gears of professional biologists like myself. There is EVOLUTION, plain and simple. Some organisms have a slower rate of evolution because their generation time is longer (humans live 80 years); while other species have a faster rate of evolution because their generation time is shorter (bacteria can regenerate in minutes). There is no micro or macro, just evolution.

    Devolution.

    There is an implied direction in evolution from simple to complex; e.g. muck > microbes > mammals > man.

    Devolution moves in the reverse direction.
