  1. Re:how, exactly on Texas Science Director Forced To Resign Over ID Statements · · Score: 2, Insightful

    The answer is that populations drift as a group. See Ring Species. Let's do a thought experiment:

    There are two colonies of large farting rodents: One lives in the northern brush where predators largely ignore them because of the smell of their flatulence, and the other group lives on a warm little island in the Mediterranean where their farts, combined with the warmth and humidity, attract bacterial infections on their eggs and genetalia. In the first group, rodents born with a slight 'deformity' that causes smellier farts, or longer or thicker hair to combat the cold, or even oilier skin and hair to keep them warm when it rains, are more able to survive. In the second group, however, rodents born with a 'deformity' that causes them to fart less, or not at all, or with decreased smell, are more fit. Furthermore, finer, sparser hair allows them to stay cool when they run from the occasional predator, and the question of dry vs. oily skin and hair seems not to matter at all.

    There are hundreds of traits like this that can come up in different environments. Sinus size, leg length, bone shape, sweat glands, skin pore size, ability to digest certain toxins, ability to respond to certain plants as immune stimulants -- the list could go on forever. The 'deformities' that work propagate through the population until the individuals without them are the odd ones out. They become the 'low hanging fruit' for predators, or are simply shunned by potential mates who want the genes more suited to the environment. Speciation "has occurred" when most or all of the members of one population have become different enough from the other population that offspring don't (or very rarely) survive, and/or are infertile.

    It may not even be the selected traits that are causing the speciation. It could be genes that have no selective pressure at all, that simply 'piggyback' on the same chromosomes as the enhanced genes, that cause an incompatibility. Even in identical environments, since mutations are random, two other phenomena occur: Different traits have survival advantages for different reasons, and the same feature develops independently multiple times. If a source of food goes extinct in the area (a particular family of nuts, we'll say), the rodents can go in several directions -- and probably would, if they were on opposite sides of a river or mountain, or on two nearby but well-separated islands. A rat with stronger teeth or a shorter jaw will be healthier because he can eat tougher nuts instead. A rat with longer legs, or a better tail for balance, or a longer snout can catch insects more easily. But the same physical trait can come about in several ways. Perhaps some of the rats have longer legs because of hormonal changes, whereas other rats grow an elongated spongiform pattern in their bones, while still others grow denser, thicker, longer bones because they can digest more calcium from the same food.

    The rats could even have been in the population for hundreds of years, through the good times, but now that something bad has happened, they're pretty much the only ones who will survive. Survival in the island climate may have been completely neutral to hair and skin oil, or the direction of hair growth, but if the rodents had to start swimming for some reason, perhaps to avoid a new predator, those traits would start to matter very quickly. It could even be a one-time event. A pack of predators gets lost, and wanders into a rat camp; Those that are best able to climb trees, or dig a hole deep into the ground, or swim out to a rock for safety, are the only ones that survive. And, therefore, only the chromosomes containing those genes still exist for that population.

    Whenever the 'standard' set of genes for one population changes, you increase the chances that they won't mix well with another set to create a viable organism. In the end, after several hundred generations, provided that the relevant traits occ

    This is a good reason for why compulsory public schooling is a bad idea altogether. We live in a different world now, but most really successful people in our nation's history learned a lot from their parents, community leaders, and friends' parents. If they went to school, it was for a few years, to become numerate and literate, but then it was right back out again. The primary source of education, from adolescence through adulthood, was books -- including the majority of our founding fathers. Now, less than half of Americans read a single book in any given year, but I digress. Public schoolteachers have forever been the bottom of the barrel; I believe that school is a demotivating and only marginally educational experience for many students, but it's hard to imagine that this will change for the first time in modern history (or quite possibly, human history).

    We don't think of physical strength or athletic ability as "fixed", just waiting for us to "learn to use it." We need to think of intellectual activity in the same terms that we think of physical activity.

    Which is pretty much how the parent poster put it. Your genes AND your personality define limits on your ability to exert yourself physically. Your upper limits for intelligence, physical fitness, and many other traits are indeed in your DNA, but you must reach them for the limits to be relevant. If you teach a child that athletic ability does not improve with exercise, he will not be likely to exercise and obtain the corresponding benefits. The article suggests that if you teach a child that academic aptitude is not strengthened primarily through study and hard work, these, too, will be eschewed.

    But, by the same token, two children of different families or different ethnicities can do the same exercises (mentally, physically, whatever) and (1) progress at a very different pace, and also (2) reach different absolute limits of ability regardless of effort.

The BMI Pegs me as obese, but my last body fat measurement put me at 21% body fat -- a little overweight, but by no means obese. To reach obesity, actually defined as 25% or more body fat, I would have to pack on eight pounds of fat and no additional lean tissue. If I somehow shed 41.5 pounds of this fat, down to 174 pounds at roughly 2% body fat, which is quite unhealthy and can result in joint damage and organ failure (and therefore death), BMI would peg me at 23.6 -- the very top end of the "healthy" range, close to overweight, and significantly above the accepted "underweight" range, defined as a BMI of 15 to 18.5.

So, if there are complex paths of execution, you'd only run them a fraction of the time, on cores that are pretty bare-bones to start with.

And, more pertinently, is it an appropriate medium to capture the interest of a younger, disaffected generation? The intent of Japan's law here is to limit the public's exposure to the politicians' direct message.

    Most recent grassroots campaigns are started online. AFAIK, nobody is talking about stopping community efforts to get the word out about a candidate. The potential benefit is in keeping the politicians and their paid interests offline and limiting their exposure to the public. It prevents the most well-funded candidate or political action committee from having multiple staffers constantly astroturfing on myspace, or bombarding you with advertisements. And, it should cause the size of the campaign to more closely reflect the number of people who genuinely want the candidate elected.

    This is probably part of the reason the boomer generation has been able to behave the way they do -- they receive all of their information top-down. Perhaps if they weren't inundated by thirteen political advertisements per hour on TV and radio, and didn't have flyers in their mailboxes weekly, they could be a little curious about what's really going on. And if every article about a candidate online couldn't link back to that person's propaganda-filled website, that could be good, too. As it is, most people think they already know what's relevant. So, while it's far from certainty, restrictions like this may be a solution to the passiveness and complacency you mention above.

    But caring isn't enough. We have to go further and start convincing our parents and bosses to think again. Like it or not, a lot of this complacency and feeling helpless is justified: The Baby Boomer generation is 77 million people here in the US, compared to 44 million people for other age groups over the same time span. In Japan, it's worse. Their social safety nets are even *better* at causing children to be a net liability instead of an asset. That means people, through greater perceived benefits, are more deeply committed to the status quo, and there are fewer young people to oppose the system.

    Perhaps a little real-world experience is just what the younger generation needs so they can feel ready to decide for themselves. But I hardly think online advertising and second life pavilions are the best way to convince them that there is a real world in need of their attention, and that they should start to give a rat's ass about what happens beyond the walls of their apartments.
