What I want to know

Why do I yawn when I see someone else yawn?

Re:What I want to know

A doctor once told me that most yawns (not all) were a sign that you had high levels of C02 building up in your bloodstream. (Thus, it happens more often when you're sleepy and not moving around much) Yawning slowly expels most the gas from your lungs and causes you to deeply inhale, hopefully getting more oxygen than carbon dioxide in the mix.

Seeing another person yawn triggers the desire in you to yawn for the very real purpose of getting rid of your excess C02 as well. This may be because we know that if one of us is getting sleepy or deprived of oxygen we all are, or if one of us is in a location that is prone to oxygen depletion-- the bottom of a cave or burrow, for example-- then we need to move to an area that is more open to moving air.

Humans have a lot of responses like this. When one of us gets sick and vomits, anyone else who sees it also feels sick and tries to vomit. The implication being that if one of us has eaten bad, possibly toxic food, the rest of us should try to purge our stomachs before it affects us.

Try this the next time you're at home with your dog or cat. Yawn widely and deeply in front of your pet. Chances are, you can make your pet yawn. This is an old, *old* mechanism.

I know I'm yawning just thinking about it.

Take THAT creationists!

Score one more for the we came from a puddle of sludge team!

Not that I wouldn't prefer creation over evolution. Probably wouldn't have hiccups. Thanks a lot, natural selection.

Re:This is an idea - a theory, for goodness sake!

I think you're being overly hard on the idea proposed in this article and overly optimistic about the function of Slashdot. The point of the article is that this is an interesting hypothesis that fits known facts and eliminates some of the problems of other theories that have been proposed. Although it will be, as one scientist notes, very difficult to prove, the scientists proposing the theory do in fact suggest how they might pursue experimental evidence in support of their hypothesis.

Does it "matter?" I think this article is fascinating. The suggestion that specific adaptations might persist beyond their usefulness to an organism because they form a foundation for later adaptations raises really interesting questions about how complex neurological behaviors are "built up" in organisms, and research in this territory could lead to a greater understanding of the line between inherited and learned behaviors, and the evolution of neurological response. That's cutting edge.

Science is indeed more than speculation but science begins with speculation, hypothesis, and theory. When I want hard science news I go to the resources in the scientific community, I read my Chemical and Engineering News magazines. 95 percent of what I read there is so dry and technical it would be pointless to post it on Slashdot.

"Münchnones, or mesoionic 1,3-oxazolium-5-oxides, are versatile substrates for 1,3-dipolar additions in constructing biologically active heterocycles. They usually are made by multistep synthesis, but now, Bruce A. Arndtsen, an associate professor of chemistry at McGill University, Montreal, and coworkers have come up with an easier way [J. Am. Chem. Soc., 125, 1474 (2003)]."

That's "real" science reporting. And it is definately more groundbreaking, in the immediate sense, than an article speculating about hiccups. But there is nothing wrong with a "color" science article that makes me think and wonder and dream a little bit about larger issues.

Tonight, we'll interview a man who's had the hiccups for 27 years!

*hic* Kill me. *hic* Kill me. *hic* Kill me. *hic* Kill me.
