I wish anthropology would say, "well, this is our best guess right now." But what i got is THIS IS THE WAY IT IS, you heathen monkeys!

Because, to support Dr. McCarthy, we just have to look at dogs. When humans started working with dogs, we now have umpteen million breeds that weren't there before in the record.

And we really should study Avocado trees. (and apple trees) Each seed is a hybrid, and does not breed true. If you want a Hass avocado, you have take a cutting and splice it into a root stock. Farmers know all about this, but scientists do not have many papers on it. You would think mapping out Avocado genes and noting changes between generations would give a lot of info.

Lastly, for this reply, i feel we will find MORE things that affect change. Like, the magnetic field of Earth. (and we find that, outside that field, things do not grow the same, or not grow at all) Life elsewhere would be a function of that magnetic field. And then we have the various non-physical layers (i hope we get tools to see them soon) and we seem to have some "Morphic resonance field" something that keeps species a species, and it changes, and all the species change. And, i bet there are more than one of these layers.
