FWIW, my wife is one of those people who are sensitive to salt...only in her case she's DRAMATICALLY sensitive to salt. She tries to keep her salt level at about 300 mg/day. I worried that this was dangerously low, but her doctor, after studying her blood level, said that she was keeping her sodium at precisely the correct level. This despite being on really aggressive diuretics (so much so that she is prescribed potassium supplements twice a day).

OTOH, I don't follow her diet, and probably had better not. So I use soy sauce and Tabasco sauce (green), and order things with normal spicing at restaurants. Most people would still consider my diet generally low sodium, but there are degrees and degrees.

My real point here is that different people can have quite different dietary needs. Don't assume that because something works for you it will work for someone else. It might, but it also might not.

Actually it does preserve you as well. I was told during the Vietnam war that while Vietnamese corpses would decay grossly within a couple of days, US corpses lasted well for a week. I suspect some hyperbole there, but that's what I was told. The "informant" suspected BHA and BHT, but gave no evidence.

Now this doesn't say much about being healthy, but it seems to make for a well preserved corpse.

I'm still trying to figure out how I didn't know about it until just recently.

Oh, I'll tell you why. Because season one only recently came to Netflix. It's the same as with Preacher, and Hap & Leonard and other cool shows. The target demographic (idiots like me) don't watch cable TV, but when it comes to Netflix, we're all over it.

I'd be reluctant to form that conclusion with the known (to me) evidence. How much of the bone fracture seems to have happened while the bone was fresh? If all, or most, then that's a reasonable point. If only a bit, then I suspect a sabretooth of the original fracture, and humans of much later work.

FWIW, I don't have access to Nature, and haven't looked at the article, so perhaps they explain this. And "fits within a broader pattern of Palaeolithic bone percussion technology in Africa, Eurasia and North America." seems to be including prior known North American patterns.

Certainly it's possible that the evidence is much better than I am assuming, but I'll wait for a consensus before assuming that. I sometimes for solid opinions on matters as much out of my field as this is, but I try to have solidly known evidence with agreed upon interpretations to base them on.

I'm not sure I buy skull morphology as being evidence of grammar. OTOH, there's evidence that chimpanzees have a rudimentary grammar sense, and they split off quite awhile ago.

If you want to say there isn't any better evidence offered for the development of language, that's plausible (though I'm not sure), but I don't find it really convincing. Particularly as it appears that chimpanzees can be taught language (rudimentary), they just don't teach it to their offspring. This might be related to the FOXp2 gene (a family that lost the human variant also lost language), but that's hard to pick out that far back...but I haven't heard that it influences skull shape.

IIUC, at certain of those periods there was an ice bridge between the continents. Such a crossing wouldn't have been very comfortable, but it might have been possible. And are there any plausible prey species (caribou?) that could have been being chased, and if so, what does their genotype show? When did horses cross from the Americas to Asia? If the timing works out, a herd of them could have been pursued back.

OTOH, all early human species were already quite inbred, so I doubt that population size was the kind of restriction it would currently be. (Lethal double alleles had probably already been eliminated.) So I'd favor their die-out being based around either bad luck (some lethal disease that when through their largely genetically identical population) or competition, either direct or indirect, with later immigrants who had better tools and social organization. Which could just have taken the form of being better hunters, so the game became both leery of humans and scarcer on the ground.

AAA development keeps pricier. Cliff Bleszinski just wrote an article saying it's unsustainable. For every GTAV we get two Medal of Honors a Darksiders franchise and a Shenmue. Prices need to be raised, but folks wont' pay more than $60. Before you balk at that consider what a $55 copy of Lotus RECS for the Sega Genesis cost in 1992 adjust for inflation. It was about $110 bucks in todays money while Forza 5 sold for about half that and had hundreds if not thousands more features (especially if you count all the advanced graphics as individual features, which if you're the engine programmer/3D Artists makes sense).

Arcades had this problem in the late 90s when they needed to raise the price to 33 cents a play and couldn't. It eventually killed them.

Columbus *did* discover America. He just wasn't the only one to do so. His discovery was enabled by his ignorance of prior discoveries.

FWIW, he wasn't even the first European to discover America. Nor, probably, were the Vikings. E.g., there were Irish sailors who had legends about a land across the sea. They sound like elaborations on something quite believable. Buckminister Fuller suggested that the Phoenicians circumnavigated the world. I didn't find the evidence convincing, but it was a plausible theory. Certainly the Chinese visited, though the evidence that I know of is only in South America.

Which steam engine? There's no "the steam engine". Hero of Alexandria had a steam engine, which was used as a toy by wealthy churchmen through most of the middle ages. I don't recall ever hearing of it being adapted to doing work, but it could have been, just like the Stirling (steam) engine is (was?) quite common as a desk ornament among a certain class of techish administrators. But it's rarely used for actual work.

Often there are reasons why a certain tool wasn't developed usefully, but these are often hard to determine from a distance.

Comment Your point about tuition isn't true (Score 1) 503

And I wish people would stop repeating it. It's one of those lies with just a little truth in it. Yes, tuition at private for profit Universities is affected by secured loan programs. That's not true for public Universities. The 538 blog has an excellent article on it but I'll save you the time and cut to the chase. We slashed federal subsidies to public Universities. That money had to be made up somewhere. College really is that expensive. We were hiding that expense to encourage a well educated population.

Comment Re:Unlikely (Score 1) 206

Welllll..... My guess is that the problem is with the interpretation of the evidence. Say the Mastodons died 130,000 years ago and their bones were broken 10,000-15,000 years ago...what evidence would contradict that theory? That would probably imply that the bones weren't processed for meat (or marrow, either), but rather for useful bone fragments. Useful in what way? That's hard for me to say, possibly decoration. I'm not sure how good an arrow head or spear point a piece of bone that old would be, but it could easily be distinctive.

But I'd prefer to look at it as the next step towards an artificial womb that can raise an oocyte to an infant. Your view is more accurate for the current version, but the developmental vector is towards the other view. If we're guessing future consequences, then the current version is less important than the fully developed version. Of course, if one is trying to guess the timeline, then a current accurate measurement is more important...but I suspect that even were I to read the original article they'd be lots of hype, and engineering problems that aren't mentioned.

So it depends on your purposes. For my purposes the important information is that development is being pushed along this line.
