The Role of Human Culture In Natural Selection
gollum123 writes with this excerpt from the NY Times: "... for the last 20,000 years or so, people have inadvertently been shaping their own evolution. The force is human culture, broadly defined as any learned behavior, including technology. The evidence of its activity is the more surprising because culture has long seemed to play just the opposite role. Biologists have seen it as a shield that protects people from the full force of other selective pressures, since clothes and shelter dull the bite of cold and farming helps build surpluses to ride out famine. Because of this buffering action, culture was thought to have blunted the rate of human evolution, or even brought it to a halt, in the distant past. Many biologists are now seeing the role of culture in a quite different light. Although it does shield people from other forces, culture itself seems to be a powerful force of natural selection. People adapt genetically to sustained cultural changes, like new diets. And this interaction works more quickly than other selective forces, 'leading some practitioners to argue that gene-culture co-evolution could be the dominant mode of human evolution.'"
just wait until it becomes culturally acceptable to intentionally modify our genes using technology.
First culture is a meme post.
Culture is a parasite and the host is people.
It just wants to propagate itself.
The people conducting that study were completely confused:
The study takes the American view of liberal vs. conservative. It defines "liberal" in terms of concern for genetically nonrelated people and support for private resources that help those people
Liberals in America think *public* resources should be used to help others. Conservatives think that private resources should be used.
Ah, yes. Slashdot... where correlation does not mean causation unless the study supports your prejudices.
Does high IQ produce the bent away from conservative values and religion? Or does high IQ cause one to feel "superior to the masses", arrogance and then a rejection of these values? The study is not able to go into this.
And assuming this is the same study as the one I read... was done on a college population (brilliant sampling technique, I must admit). It also found that the "ubermensch" has an average IQ of 103. Clearly our atheist, liberal overlords are far beyond what I can even imagine intellect wse.

You can always hope the current crop of Neanderthals will be bred out as their namegivers had.
I wouldn't bet [imdb.com] on that.
You do know that movie was fiction, right? Hmm... maybe the current crop of religious neanderthals will just be replaced by a moviegoing crop of neanderthals.

The write up is misleading on many levels, and reflects a very nineteenth century understanding of evolution. Fitness criteria are constantly changing, and success changes the fitness landscape. Of course culture will impact evolution. The idea that it could somehow protect from selection pressures is just silly. Culture may protect you from the cold, by giving you a fur coat. Or you could evolve a fur coat, but would you then claim that the fur coat protected you from selection pressures and 'slowed down' evolution? Evolution isn't going some place, it doesn't have a direction, so it is a bit misleading to talk about how fast it is going.
- None can love freedom heartily, but good men; the rest love not freedom, but license. -- John Milton
Culture cannot play a role in natural selection, by definition. It does play a role in selection and evolution. That role is known as cultural selection.
Notice the phrasing "gene-culture coevolution" is consistent with Dual-Inheritance theory which considers cultural (behavioural) transmission as an evolutionary process on its own. This can also be extended with Epigenetic mechanisms and Symbolic transmission modes. Technology evolves too and seems like a sensible extension. Its not so far fetched when you consider that Reproduction (or amplification in the continuous case), Variation and Selection are sufficient conditions for evolution. Keep in mind cultural evolution is Lamarckian though... and different in many other ways too.

the ultimate effect of a conservative ideology is a third world country: a rich upper class of a few, and a vast underclass of poor
there is no room for the middle class in conservative ideology. this includes no room for middle class idiots who believe the corporate propaganda about "evuls socialisticisms". some people are their own worst enemy
the money you have in your pocket is an abstract expression of the wealth of the society you live in. if you do not invest in your society, the money in your pocket loses value. if you invest in your society, you are paid dividends of a richer society, which pays you back with more business opportunities, etc
"but dem freeloading welfare queens..."
oh shut up retard. take a look at denmark someday. tell me they aren't happier healthier and wealthier than the average american. and then take a look at their tax rate
i'd rather be taxed to high hell than worry about declaring bankruptcy if i get cancer
but the conservative answer about a rising poor underclass (made up of previous middle class people) is to buy more guns
the greatest irony/ tragedy/ comedy is how many previously lower middle class people who are now the new american poor (because of conservative initiatives like gutting depression era financial protections that created the real estate bubble) support with such rapturous passion the gutting of social safety nets that only exist to serve them. some people are full of so much stupidity and hatred- for their own neighbors, their own society, and their own government, that they only destroy themselves
but i'm not going to let the morons take us all down. and if you read my words and agree with me, roll up your sleeves: there is a real life zombie apocalypse of propagandized retards out there, and we need to fight them to save our country from their self-destructive conservative stupidity

Milk drinking is a direct result of culture - the domestication of cattle for meat and dairy. None of our human ancestors could ever drink milk from a wild Aurochs and survive - (think 2-3 meter horn span, one metric ton, and very touchy).
the nobel prize winner, john eccles - brain neurologist considers the known/experienceable world to actually be comprised of three 'worlds' -- i) that of matter, ii) that of states of consciousness, and iii) objective knowledge -- 'the sum total of human culture':
http://en.wikipedia.org/wiki/John_Eccles_(neurophysiologist)#Philosophy
there is not only an evolution of the physical human form, but also an evolution in the states of consciousness mankind has achieved in order to attain to the states of consciousness which prevail in order to, for example make scientific and logical judgements -- evolution of consciousness, and its consequences must be taken be taken into account, because all that you see as the effects of HUIMANS -- cities, bridges, buildings -- is all due to a change in the consditions of consciousness that humans have developed.
in fact, the social organization may be more important than the material organization. there are enough physical resources and technological expertise on this planet to feed every woman, child and man on this planet -- given that we are adequately socially organized -- this is not yet the case, so war and poverty are not necessarily a lack-of-resources issue -- but a social one.

Education can contribute to IQ, though. We've been seeing a steady rise in IQ points for quite a while now, and the best theories I've seen suggest that it's directly caused by the rise in abstract-thinking skills amongst the general populace. Since abstract thinking is a learned behavior, this certainly suggests that IQ measurements - no matter how well designed - will be influenced by the level of education of the person being tested.

It's not just humans impacts on themselves. Humans have become 'superpredators' speeding up the evolution of the species they hunt and harvest at rates far above what is found in nature. Hunting techniques such as bagging the biggest trophy animal to commercial fisheries where mesh openings in nets capture the largest while allowing the smallest to escape has impacted the natural selection process. Removing the strongest and biggest species from the gene pool has resulted in offspring characteristics such as reduced body size and lower reproductive age.

how the average lower middle class person is supposed to pay for healthcare in this country
the conservative answer is "shut up and get busy dying"
you don't have an answer beyond that, and it makes my blood boil. the cost of a sick society is much higher than the cost of a health care system which is attuned to taking care of people, rather than raping them for profit
"the ultimate effect of a conservative ideology is a third world country: a rich upper class of a few, and a vast underclass of poor"
The ultimate effect of a liberal ideology is a third world country: a rich elite ruling class of a few, and a vast underclass of dependents of the state.
can you point to such a society for me please? this is a pleasant fiction to support your bankrupt thinking, as this country doesn't even exist
meanwhile, i can point to many countries without a strong central government which naturally gravitate towards a rich upper class and the vast majority being poor. i don't understand why you cannot see that without strong functioning social nets this is the inevitable result of your ideology. how many examples of how many third world countries with weak central governments and no protections do you want? and yet this third world status quo is EXACTLY what you are arguing for. can you not see the obvious result of your ideology?

(It probably does.)

Primates evolved trichomatic eyes to find fruit better. Most mammals are dichromatic. Now humans eat more meat, cooked food, more starch from grains and more dairy from cattle. Each diet change affected the genes . One could argue the next stage- hyper nutrition and processed food- selecting against humans with metabolic disease like diabetes, obesity, and bad hearts. This was very interesting article.
Huh? The number 100 has continued to rise? :P
Smartass :)
On the off chance that you're serious - and for those who aren't aware - IQ tests are re-normalized periodically in order to keep 100 as the average. In other words, if a person today and a person 30 years ago took the exact same IQ test and got the exact same answers, the person writing it today would receive a lower score. So yes, the average IQ does keep getting higher, even though it stays at 100 :)

Been awhile since I tried slogging through Natural Selection, but the impression I got was the choicest survivability attributes may be fleeting things. On top of that, the sexual selection attributes might even conflict with survivability. So, you could be the moose with the prettiest antlers that get all the girls/cows, but you'd get locked up in brush and starve to death. Same thing with humans. The hottest girl you've ever seen might be too dumb to tie her shoe laces. How's that help further the species, besides making you extremely pleased during your breeding years? So, just because we've evolved some attributes or culture doesn't say a damned thing about how good it is for humanity either right now or in the long run. Chance seems to play a very large part in the game.
I swear to God...I swear to God! That is NOT how you treat your human!
Take the example of teosinte (originally Zea mays parviglumis), a grass that has since evolved from a very fit organism to a biological freak: its reproductive organs are encased in a husk and located in a place that makes reproduction less probable unless it's mediated by another organism with opposable thumbs. Why did it evolve this way? Because humans really liked to kill the plant and eat its embryos, and thus wanted to ensure the survival of the species.
And while Zea mays parviglumis is still around, you're probably less likely to run into that plant than the more common mutant subspecies that humans evolved: corn.
We can argue back and forth about who has evidence, since the tendency is to simply dismiss the other side's evidence as non-evidence... with any debate, that's the case. Just look at the AGW debate.
The ideological side of the AGW debate, sure. On the science side, it's quite a bit different.
The word "evidence" has a pretty clear meaning. If you can submit actual evidence, I'd be more than happy to look at it. On the other hand, if all you can do is pull out Pascals Wager, a God of the Gaps argument, or a claim that evolution violates the second law of thermodynamics ... then you don't actually understand what the word "evidence" means. Those types of arguments should be rejected offhand, regardless of what claim you're trying to prove. If someone was trying to argue for a position in which I do believe and was providing "evidence" of similar quality, I'd reject their argument too, and call them out on it. Ideology should not be a basis for accepting or rejecting evidence.
In other words, many of our words seem to have gotten quite broad in meaning
Yes, that's true. That's why when people ask me if I believe in a god, I usually say "which one?". There are at least a few thousand different definitions. For all I know, your definition of "god" might be one that I can believe ... but I sincerely doubt it :)
