Four Stone Hearth #101 – The Phoenix Edition

phoenix-3

This is the Phoenix edition of the Four Stone Hearth.  It’s 100th installment saw the relinquishing of power of the original editor in chief, Martin Rundkvist of aardvarchaeology.  I want to extend my thanks to Martin for turning the Four Stone Hearth into the shining example of what is possible with a Blog Carnival.

We now have a new head-honcho, Aferensis.  Most readers will know him, and know he’ll do a great job at keeping the flame burning for a long time coming.

We’re heading into a new age, and it seems like it is appropriate that this is the 101’st edition.   It’s been speculated that Blog Carnivals are going out of fashion – as evidenced by the demise of a few great ones like The Tangled Bank and The Skeptics Circle.

I think, however, that the blog carnival has an important place in the dissemination of science information to the general reading public.  If nothing else, it provides a hub through which lots of great info can be read that might not have crossed ones radar.  But, it also is a way for bloggers to interact, have fun, and keep the flame of science blogging burning bright – no small issue since most science bloggers are not paid for their blogging.

So, with that in mind here’s the 101’st collection of great blog posts in anthropology:

We’ll start with a hat tip to the previous editor of this blog carnival, Martin Rundkvist, with Archeology 101: Chronology, or, How Can I Get a Date? A good chunk of Creationists base their refusal to believe in human evolution on their total lack of understanding of how scientists date things.  Martin breaks it down for us.

Over at Athropology.net we have a post entitled, “A Curious Look At The 3.39 Million Year Old “Stone Tool Markings” From Dikika, Ethiopia.”  Here’s a quote:

I don’t know who this is worse for, the editors & reviewers over at Nature or the authors of the article who can’t tell the difference between crocodile teeth markings and stone tool modification.

Them sounds like fightin’ words!

You think your neighborhood is bad?  Welcome to Texas:

The family says their dog scared up the monkey under the backyard patio and the creature then chased the woman into her garage – trapping her for over an hour.

Bonvito has two posts.  The first discusses the counterintuitive idea that male primate rank has little to do with reproductive success:

Rhesus females also prefer novel males for mating. This female mate selection is thought to be one of the primary factors why males migrate out of their natal group. The migrating males, who are at the very bottom of the hierarchy, have to be in constant high alert, especially so during the mating season when high ranking males are on guard (i.e., those who are on top are particularly protective of their position on this period).

The second is about Jane Goodall’s connection with Gary Larson’s Far Side.  Is the famous primatologist able to take a joke?

One of the biggest mistakes we make as humans is our tendency to glorify the past and sanitize it.  For instance, we look up to Napoleon and Caesar and totally ignore the horrific violence and death they caused in their selfish pursuits of power.  Judith of Zenobia: Empress of the East takes a hard look at the Peloponnesian War and it’s consequences. A quote:

The bodies of the dying were heaped one on top of the other, and half-dead creatures could be seen staggering about in the streets or flocking around the fountains in their desire for water.

Anthropology is not just about long dead people or exotic tribal societies in Africa.  It’s also about modern cultures and modern living.  Krystal D’Costa, of Anthropology in Practice, has a post about the struggle of keeping the faith during Ramadan and still running a successful food cart business.

While many Muslims choose to slow down during this period, for those who make their livelihood as food cart vendors, it can present a personal challenge: They are surrounded by foods that they themselves cannot eat all day long. It creates a challenge for the individual, but also for the business as they have to rely on sight and smell to gauge flavors

She also has a great post about the odd fact that Nescafe is so popular in coffee producing countries!

… why does Nescafe seem to be popular among coffee producing countries that theoretically have access to their own supply of coffee beans? Anthropologist Kevin Birth offered some suggestions that cover the expenses associated with grinding and brewing beans, but today we’ll look a bit more closely at the relationship between local consumption and consumer identity.

You think the life of an Archaeologist is easy?  Watch out for moose! Magnus Reuterdahl of Testimony of the Spade gives us a glimpse into his world.

For those who don’t know, Eric Michael Johnson, formally of the Primate Diaries on ScienceBlogs.com, is in exile.  Well … he’s in blogging exile.  And he decided he was going to go on tour.  His most recent stop is at Anthropology in Practice where he talks about the cultural divides of Myspace and Facebook, functional racism, and class. Great stuff.

In the wake of many teens departure Boyd describes what was left behind as the formation of a digital ghetto. Abandoned Myspace profiles “often fell into disrepair, covered in spam, a form of digital graffiti [as] spammers took over like street gangs.” In contrast, Facebook was seen as a virtual gated community with the “same values signaled by the suburbs.” The class bias represented in this was extremely telling in 2009 when Facebook and Myspace converged with roughly equal numbers of visitors. A New York Times story about this convergence was titled “Do You Know Anyone Still on Myspace?” This confession by the author is extremely revealing. Given data showing equal traffic his preference was to make assumptions based on his network of friends, a trend that is likely to be pervasive throughout the mainstream media on stories that are much more important.

A Primate of Modern Aspect has a piece about ape sex, the human inability to stay objective, and evolutionary psychology.

Here’s the thing that gets me all riled up when I read these sorts of op-eds: Lots of people study primate sexuality.  It’s a fascinating field.  And who the primates are having sex with is only part of the fun.  We know about stress, group dynamics, cognition, and general evolutionary theory because of the good, hard work of these people who are driven by curiosity. But for some reason, the only time primate sexuality gets any attention is when we turn it into a debate about how humans should be having sex.

We never say, “Hey, those muriquis are too promiscuous.  Don’t they know that all of their close evolutionary cousins are polygynous?  If they just did what came naturally to them, they’d have a lot less psychological stress.”  Or, “Those gibbons are so sexually repressed.  If they just gave in to their natural predilection for promiscuity, I bet those nasty gibbons would have fewer territorial disputes and gibbon society would be much more peaceful.”

Help! These Baboons need a name.

A Hot Cup of Joe deconstructs the PseudoArchaeology of Glenn Beck.

It should be no surprise that, since he has little grasp on the rest of reality, that Glenn Beck would fare any better at understanding archaeology.

Anna of Anna’s Bones adds the third installment to her “Stripped” series:

I felt the blood rush towards my head. Everything was upside down. I adjusted my hands according to yoga instructions I had been given many years ago – “you have a very long back” I had been told. I tilted my head to the side to meet 50 pairs of very confused eyes staring intently at me… I was, after all, doing downward dog in a Paleoanthropology workshop.

In DIY Knapping, at A Very Remote Period Indeed, we get a nice video showing how hard this practice really was.

Kris Hirst discusses Gary Feinman’s photo essay on About.com on a Regional Survey in China:

Mick Morrison has a post about the teaching of Archaeology, digital learning, and blogging (rather relevant to a blog carnival, I dare say!).

Finally, here is a picture of John Hawks, a Paleoanthropologist who clearly loves his job:

Paleo vs. Neo Carbs (not Cons)

(cross-posted @ the Dojo)

Dr. Lam has a post on the link between sugar and all the ills of humanity. While I’m certainly for a low sugar diet (and the proscriptions in the post are largely fine), he brings up some points that are patently false (and therefor irk me something fierce).

In particular, he quotes (favorably) Robert Crayhon, the dude who created the “Paleo Diet”, in his distinction between what Crayhon calls paleocarbs and neocarbs (no, neocarbs are not a description of Karl Rove and his cronies):

Paleocarbs are carbohydrates that have existed since the beginning of time. They include fruits, seeds, and vegetables that primarily grow above the ground. Generally speaking, these are “good” carbohydrates as they provide the body with needed antioxidants, fiber, nutrients, and calories in a slow-release fashion.

Neocarbs are carbohydrates introduced within the last 10,000 years when modern agriculture first started. These include grains, legumes and flour products. Some neocarbs like legumes are grown above the ground and are nutritious. Others are grown under the ground. These include potato, yam and carrots, which are high in sugar and therefore not optimum for heath.

Ridiculous! “… have existed since the beginning of time.” No they didn’t! The most paleo of carbs are BY FAR simple sugars. Glucose, a very simple sugar.  The earliest life forms (that had any sort of complexity) on earth were most certainly bacteria, and they use simple sugars all the time for cellular respiration as well as other processes.

True ‘neocarbs’ are anything at all having to do with plants, like cellulose. These wonderful complex carbohydrates that we are all so fond of eating for our health (a good thing) didn’t pop onto the scene for quite some time. And the newest of them all are fruits and vegetables! They are, in fact, a ridiculously recent invention.

Fruits and veggies come from flowering plants. Up until the Cretaceous period, there were no such thing as flowering plants. That means that early herbivore dinosaurs (like the Brontosaurus) didn’t eat fruit, they probably ate pine needles and other hard to digest foods (partially explaining the VERY large gut needed to ferment, digest, the food). That’s fiber, baby!

Fruits and vegetables actually constitute a relatively simple sugar in comparison.

The next complaint is about the idea that his neocarbs are all recent inventions. Many of them are new varieties, but we have to be careful. Wheat existed previously in the wild. We didn’t engineer it in the lab. We just selected for the right versions for long enough that the domesticated variety is now far easier for us to harvest and process.

Simple sugars are not good for you (except during a workout). But the reason is NOT because they are “newer” inventions in the history of life. Simple sugars are the ‘oldest’ of all sugars (still misleading). That isn’t the point. The point is that your body doesn’t do well when inundated with that much sugar.

We humans are a new ‘invention’, and as such we require a NEW kind of diet. Leave the sugar to paleo-creatures like bacteria and yeast.
