[ QUOTE ] Actually, to correct myself, on a technical level you are still wrong, since even with perfect migration new traits can still arise via mutation, which could permeate throughout the population. [/ QUOTE ] Could, yes, but it is highy unlikely . Natural selection is, ultimately, a probability game. [/ QUOTE ] It is neither highly unlikely, nor highly likely. The probabilities would depend on mutation rates. What I really should have said at the beginning is that a lack of migration amplifies already existing variation (and might as well be considered a source for variation). [ QUOTE ] Relating my earlier quote with your "the sum probabilities of any allele becoming dominant is > the probability of all frequencies of alleles staying exactly the same.", migration drives the gene pool to the average of the species , ie that inequality is not met..the probability of the frequency of alleles staying the same dominates. [/ QUOTE ] The bolded part is true, but migration only drives the gene frequencies to the average of the previous generation, and doesn't do so in one generation. Any slight deviations within one such generation the become part of the average for the next generation. This is a way that species can become altered without the founder affect, within their own population. Again all of your arguments only point out that decreased migration and decrease pressure via "natural selection" (that is the ease of providing enough food to get you and your offspring to reproductive age) will slow down the evolutionary process, not stop it. |

[ QUOTE ] The alpha jocks intimidate the omega nerds [/ QUOTE ] Actually studies on bullying show that the most popular are rarely involved in bullying. [/ QUOTE ] Intimidation doesn't imply bullying, necessarily. The popular do possess desirable qualities that the omegas lack, which makes them intimidating. But you are right, it's usually the more insecure ones in the middle that do the bullying. |

[/ QUOTE ] Good because I never said it would stop it. I said specifically that it "could" or "can" occur. The point is that the process is so slow that beneficial allele changes will general be so diluted throughout a population that their survival is more a matter of random chance than it is natural selection. (The debate over whether natural selection is a "random process" because it is fueled by random genetic changes has been had at SMP, and it clearly isn't, knocking out one of the creationists arguing points). |

A nit: Inevitable [/ QUOTE ] I spelled the title wrong? *self-flagellates* [ QUOTE ] I think using kids in school as a parallel to the "real world" presents some problems, mainly because kids will be influenced by the behavior of their parents, and their parents will be influenced by their status and situation in the "real world", so I don't think you can really assert that the school is an isolated egalitarian society in any meaningful way. Confident parents have confident kids. Rich parents are more likely to be confident. Etcetera etcetera. There are some interesting trends with the alpha/omega stuff, but I don't think it stands up that well. [/ QUOTE ] It's a matter of degree, imho. I agree that, all other things being equal, a child from a wealthy family will be more popular than a child from a poor family. Similarly, an adult male who successfully competes in sporting events will be more attractive than one who does not. The point is, though, that this is not particularly high on the females' selective criteria. Think about it this way. Let's say that your priorities in selecting a job are as follows, in order of decreasing priority: 1) Salary 2) Lack of stress 3) Closeness to home. If these are what you value, then it is quite possible that you will take a job with a big salary, even if it is somewhat stressful and requires a bit of a commute. If you're paid enough, these inconveniences will be compensated for. Now let's say that heavy socialism comes along and all jobs pay nearly equal amounts. Salary ceases to be a priority; it is controlled for. Now your other priorities take the forefront. Chances are now that you don't want that job you wanted before. Your first priority now is lack of stress and your second is proximity to home. Why would you want a stressful job that requires a commute? You will select something else under the new circumstances. Logically, if we assume economic status to be the first (or one of the first) priorities in a female's selective basis, and looks to be the second (or codominant), we would expect selection under communism to favor the good-looking more. Suddenly the average-looking upper management yuppie fellow is much less attractive than the rugged, good-looking construction worker. |
