Ape-Human DNA Split 29
M. Boss writes "CNN is running a story about a gene split between humans and the apes. This is the second major DNA article regarding human evolution published in the last month (the first being about the FOXP2 gene, possibly responsible for human speech and comprehension). This second story is about a gene missing in humans that is responsible for production of a sugar acid, and possibly human brain expansion."

This is an ethical issue of biblical proportion. Something inside us says that this is wrong, but the same is true of cannibalism. Cannibalism is the norm for adolescent wolf spiders, so why is it that we as human beings find it so distasteful? Same-species protein is wrong simply because it comes from the same species.
It's an interesting dilemma.
Do we ignore the potential to test our theories on hapless and helpless apes or do we go with our questions unanswered. Between you an' me, I'll guess that the pocket-protector types will figure out a way to test on our ape brethren.

Incorrect.
Cannibalism is wrong because same-species flesh carries bacteria, viruses, prions, concentrated toxins, and all sorts of nasty stuff that is bad for us.
Many seemingly senseless taboos have a basis in fact.
Why is it we eat lots of herbivores (chickens, pigs, cows, etc), but we don't eat carnivores (dogs, cats, tigers, lions)? Is it because it doesn't seem "right", or because carnivores being higher up the food chain concentrate toxins?
Why don't Jews eat pork? Is it because God said so, or is it because God (and his numerous assistants down here) noticed that before refrigerators you got Trichinosis from eating pork?
Why do many organized religions have taboos against sex outside of marriage? Is it because you will go to hell if you have sex, or perhaps it is because people recognized that lots of promiscuous sex was correlated to diseases?

Oh, piffle. All it takes is a little care and preparation of the meat. Also, eating healthful specimens is better than munching away on Johnny CouchPotato.

Who's "we"? There are several asian cultures where dog meat is considered a delicacy. Anyway, that said, hunter-gatherer humans would eat the meat from any animal preyed on. The main reason our diet currently consists of herbivore flesh is that herbivores are easier to domesticate and raise in an agricultural environment. And, historically, most herbivores would be much less dangerous for humans to hunt and kill.
If it were about avoiding toxins, nobody would be smoking, drinking, overdosing, etc. We, as a species, are smart, but not that smart.

Ask some Jews and you'll get one answer, ask science-oriented non-Jews and you'll get a different answer.

It's because there are vast numbers of people out there who really subscribe to the idea that if it feels good it must be wrong. If sex were really considered okay today, we'd never have BS "storks bring babies" stories taught to youngsters. Unfortunately, the world is full of people for whom even nudity is something of which to be ashamed.
Really, man, you give too much credit. You state that many seeminly senseless taboos have a basis in fact, but I would say that many of them have a basis in nothing more than psychological control. And the church still uses those tactics today. How...modern of them.

We eat lots of herbivores because it is more efficent to. We need a heap of plant material to feed a herbivore, but if we farmed carnivores, we would need a heap of herbivores to feed the carnivores, and a truely massive amount of plant material to feed the herbivores. It's far more efficent to eat the stuff at the bottom of the food chain.
That being said, if you got your meat from hunting carnivores, it wouldn't do you any harm.
Why don't Jews eat pork? Is it because God said so, or is it because God (and his numerous assistants down here) noticed that before refrigerators you got Trichinosis from eating pork?
While pork can cause health problems, virtually every type of food (meat especially) can do the same. Why pork and not chicken? It was probably a cultural thing that got passed down through history (as far as I know, the non-eating of pork is the oldest archeology dated Jewish custom).
Food taboos (Score:2)
The anti-carnivore taboo isn't nearly as universal as you think it is. Dogs are a part of many Asian cuisines, and there doesn't seem to be any associated health problem -- other than PETA death threats. Some popular food animals (inlcuding a couple you cite) are thought of as herbivores but are actually carnivores or ominvores -- Salmon, pigs.
Many Asian cultures seem to have a taboo, or at least some aversion, to eating draft animals. No obvious answer for that one. Then there's horsemeat -- popular in continental Europe, gross in English-speaking countries. Cuteness factor?
Health issues are often cited as a source of taboo, but that's hard to justify. The usual example is the tricinosis spread by pigs. But there are easier ways to prevent this disease -- like cooking thoroughly. Every animal food, even eggs, spreads diseases that can be controlled by cooking.
(Incidentally, the fact that pigs spread trich has more to do with the similarity between human and porcine physiology. It's quite striking. Pig embryoes are sometimes used in human anatomy classes. One 16th century scientist even though that humans evolved from pigs. I'd tell you his name, but I'd stand accused of a gratuitous pun [luminarium.org].)
Taboos have a lot more to do with defining your cultural identity, and separating your own culture from others. Jewish culture (my own heritage) is full of bizarre prohibitions. No mixing meat and milk -- you even have to have separate containers and utensils for them. (Though somehow fish is not considered a meat!) No flicking a light switch on the sabbath. (Electricity is a kind of fire, and you can't light or douse a fire on the sabbath.) No consumption of any non-scaly aquatic life. (Salmon is OK, even though they're carnivores, but sturgeon is not.) It goes on [kashrut.com] and on [jewishencyclopedia.com].
My own pet theory about the pork taboo goes like this: many, many years ago, the ancestors of todays Jews and Arabs were nomadic peoples who had a free open life in the deserts and hills. They looked down upon (and occassionally conquered or pillaged) the agricultural peoples who spent their life mucking out a living in the various river basins. Clean noble nomads raise herd animals. Filthy peasants raise disgusting dirty pigs. And a taboo is born. Just a theory!

Well, we're pack animals. We need to keep our family alive or we'll die too (in nature, in civilised society its a bit more complex than that). Of course, some human cultures took to eating people from neighboring villages, eating "their own kind", but not their kin. And then there are the psychos...they don't find it distastefull, but they aren't "normal", so they don't count

As far as producing apes of human intelligence, we must recall that evolution does not occur as a path to a specific end. While the absence of this gene might allow the increased brain function, we cannot say now that it necessitates it. What we may find an entirely different result in the long term evolution of apes. They face different tribulations on their reproductive trail than pre-humans faced. They are not competing soley among themselves for the right to reproduce and pass their genes to the next generation. They are competing with extreme external pressures to merely survive.

I'm hoping this post is in jest, but its hard to tell. The thing that bothers me about stories like this is that it reinforces the one-gene/one-function myth that popular journalists seem to love so much. Sure, in many cases we can isolate genes that produce proteins with specific functions that are useful. But, when you start talking about genes related to development and morphology, I'd guess (being an armchair science-geek) that that things get much more complex. No one in the news wants to talk about the extreme complexity and and inter-relatedness of genes, but everyone want to say "Hey, Scientists Discovered the Intelligence Gene!"
