Does Angela Jolie count? When I look at her, I feel a great attractive force, but then find myself repulsed when I read about the weird things she's into.
On a serious note, this is close to correct. Mathematically, there are actually three main types of selection, each of which yields different end results. When plotted as phase planes, one of these types looks similar to what you suggest, except that I can't call it "snapping to" so much as spiralling toward or away from key points.
Is the spiralling effect, rather than 'snapping to' experimentally confirmed, or is it hypothetical?BillHoyt said:
I'm afraid BD is both right and wrong. In higher animals, we've noted no stress response. (Except in immune systems, where the production of monoclonal antibodies in response to disease heavily depends on hyper-mutation regions in antibodies. This, however, is somatic mutation.) In microbes and plants, we have extensive evidence of both mutation suppression and mutation amplification in response to environmental stressors.
Don't get me wrong, BD. Evolution does not require any such mechanisms. It can get along fine without them. Specific groups of organisms have such mechanisms because they get along better with them. BTW. some of what I wrote about is fairly recent material; as recent as late 2004.
You, I, and everybody else have to sprint very fast in this area...
BillHoyt in particular, would you address my question?
It is a mathematical fact. It is simply the expression or mapping of systems theory into the biological realm.
If you know it's a math fact, then you'd know the answer. So something is amiss.
It is a math fact. It has been verified in the lab, and has been shown in the field. You can do it yourself by breeding flowers or dogs or cows. Farmers have been doing these things for centuries.
^That is an excellent link!
Thank you; glad you like it. Search on the page for "Leonard's fitness". That will take you to a section with the "spiralling" phase-plane diagrams we're discussing.
