Bingo: Dino DNA

Okay, well not exactly DNA...just a protein sequence.

If you don't know what I'm refering to, you can read a poor overview at the media outlet of your choice. An abstract from the magazine Science is here.

If you don't feel like reading that little paragraph, it goes like this. While transporting a T-rex bone, it was accidently broken. Some of the shards were sent to a scientist who upon further analysis discovered some intact proteins (not an intact DNA sequence mind you). A series of tests showed that the sequence had more in common with birds than with reptiles.

Now this isn't exactly earthshattering news: it's been pretty well accepted that the branch of dinosaurs that included T-rex had a branch that evolved into birds. This is NOT to say that the T-rex evolved into a bird of course. It is pretty exciting to see that soft tissue has survived 68 million years, however. And of course this adds support to the prevailing theories concerning birds and dinosaurs.

I've been involved in a discussion over on the Fark forums: it turns out one of my fellow Farkers has a friend who is working to oppose this new discovery. It turns out there is quite a bit of bacterial and fungal contamination, with the potential to throw off the results. Now I am not swayed by this argument; the Dino test also did the same for mastodons "proving" they were closely related to elephants (duh). For a bacterial soup to contaminate and throw off the dino sample and just happen to make it look like a bird sequence is highly unlikely, but I'll accept as possible. But for it to happen a second time and again skew it to look like the hypothesized result (of a totally different group of animals to boot) is just too much for me. Also the challenge admits that in their analogous sample they didn't find the same collagen that the original author did, just many of the surrounding features (so called "blood cells" and other structures). Without the collagen, a very material found in multicellular organisms (and not bacteria) the critique seems unfounded. I was forwarded the poster that the challenger presented at some conferences, but since his work hasn't been published yet I am uncomfortable sharing it here.

It's pretty exciting watching the scientific process in action, even as an uneducated spectator. Theory, counter-Theory, egos and reputations on the line. The challenge is warranted, of course. With a major advancement caution is always advised (we don't need another Piltdown Man debacle); and the bacterial contamination is a red flag. However, at the end of the day I'm not swayed...and besides it's one step closer to humans finally being able to ride dinosaurs. To think: this quackery might actually be possible someday!

She blinded me with...


So after finding myself drawn into one of those irritating creationism debates I decided, momentarily, that America is doomed. It's no wonder our economy is tanking, the dollar is wretched, China is catching up in the space race (with Europe caught up, Russia set to surpass us when we discontinue the shuttle and replace it with...nothing), medical research is stagnant, we're still dependent on fossil fuels (with viable alternatives more and more apparent with each passing week), etc. etc.

Science is failing us. Or rather we are failing at science.

Over half our country claims to be creationists, rejecting evolution entirely, embracing young earth creationism, and sending their money to that farce of a museum up in northern Kentucky (the creationism museum). Well that's no big deal right? It's only one tiny branch of science ("evolutionism") balanced against the entire field.

Well, not exactly. What follows is a list of other sciences that are rejected by this argument. The Yecs (young earth creationists) aren't just singling out one small "controversial" group amongst the scientific community. They're opposite nearly all of science. I'll arrange them roughly alphabetically.

Anthropology: multiple fields of science for this one, as follows:
Archaeology: My field, but I'll not spend too much time on it. Obviously there are artifacts that go back more than 6,000 years.
Physical Anthropology: This includes the paleoanthropologists (the Leakeys; Lucy et al.) It goes without saying that the ones working on human evolution, uncovering modern human remains 200,000 years old and transitional human fossils millions of years old that are rejected by the Yecs.
Linguistic Anthropology: Back in the day these were the rebel cowboys...able to track human migrations and movements through the current language trends and locations. They linked India to Eurasia (they're a people with cultural and biological origins in the Eurasian steppes (Caucasian, as in the Caucus region of the world, not Anglo-white) with a language related more to Greek than Chinese), showed how many tens of thousands of years ago the Americas were populated , and can trace back the origins of language to roots 50+ thousand years ago (ooops that's more than 6,000!).

Astronomy: By charting the stars and their locations, using devil telescopes as well as the naked eye, the universe has proven to be massive...stars we see are many many light years away. I believe the furthest that we can see with the naked eye is around 15,000 light years away, to say nothing of how far Hubble can see. However if the Yecs were right we wouldn't be able to see it. We'd only be able to see stars 6,000 light years away. After all if the Universe were created 6,000 years ago a star 7,000 light years away would not be visible for another 1,000 years. Maybe the devil makes light go faster to fool us.

Biology: Huge field, multiple areas in conflict...to name a few
Genetics (think the concept of their tracing humans back to an "eve" ~ 200,000 years ago), of course
Evolutionary biologists: (I'm pretty sure we're all fairly familiar with these conflicts) Fossil records...DNA testing...the fact that it makes predictions based on observations that are then proven through experimentation, all that.
Molecular biologists working on cancers or diseases that evolve and mutate. If mutations and change to our DNA didn't occur I'd never have to put on sunscreen (as a simple example) as the UV radiation wouldn't cause a mutation: a kink in the DNA chain interfering with vitamin B production causing cancer. If viruses couldn't evolve we'd have a working vaccine for HIV, MRSA wouldn't exist, nor would drug resistant strains of TB.
Plant Biology: This is a favorite of mine...who the heck picks on plant biologists? Well apparently the Yecs have a big problem. Why? Dendrochronology. In a simpler word? Tree ring dating. Using slow growing wood, like the bristlecone pine (the oldest individual was found to be 4,000+ years old) from a single region a pattern emerges from the rings. In wet years the trees grow more ( depositing a thicker ring) in dry years they grow less (thinner ring). I'm simplifying it as binary for sake of argument. Now with a 4,000 year sample they'll come up with a pattern. 0110001101110011101101. Or whatever. With a couple overlapping specimen they've determined that yes, this is an accurate "calender," and rings do correspond to calender years. Okay, that's great, but so what? A 4,000 year old record of weather doesn't stand in conflict with the Yecs. Oh, but it does. Using overlapping tree lives found in preserved wood they've managed to project this pattern back some 10,000 years in some regions, creating a "master pattern" for the region. Basically with sufficient overlap you can keep extending your calender backwards. So you have 3 trees:

0011110011010101010111001011010
->1001011010
01110110101101
-->10110110110111001010101101

This is a very useful tool to have, as if I find a piece of preserved wood I can look at the pattern and determine what year it is from by matching it along the pattern.
There's another problem besides the trees proving the world is over 6,000 years old. Dendrochronology was used as the control against which to calibrate Radio Carbon Dates. Take a piece of wood you know is 5,000 years old thanks to the tree ring time line, and see what sort of carbon decay has occurred. Contrary to Yec arguments C-14 isn't an assumption...it is tested against a solid and proven dating calender.

Geology: It's crazy to think that back during the 17th and 18th centuries it was the geologists who were the crazy radical scientists taking on the institution. They were the ones being "tricked by the devil" into thinking the world was old. By looking at things like erosion, land formation, and more recently plate tectonics, they were the ones who realized the world was old. Very old. Enlightenment era geologists concluded the earth had to be at least a million years old, formed through uniform change (though slight) over a very long time period. Yeah they vastly underestimated the age, but it was a start.

Paleontology: A double whammy here. First the usual very old earth argument. Secondly they find no evidence of "the flood." In fact while dinosaurs were initially argued to be evidence for the flood (they missed the boat, so to speak), and they claim all the oil in the world is from the animal matter being created (quickly) from that die off. Well that and there are records of several periodic die offs, the KT die off only being the sexiest...but not the largest (that would be the P-TR extinction: the Great Dying, where 96% of sea life died, 70% of land life, and the only known mass extinction where insects were also among the victims). I guess there were a bunch of floods...that killed fish too...so apparently God had to restart a lot. He must have been working on Vista. Secondarily the paleontologists test the predictions of evolutionary biologists. For example the big theory is that life began simply and has become more complex through time, as evolution adds new mutations and changes that prove beneficial. Sure enough you have fish with gills before amphibians with lungs. You have simple 3 chambered heart cold blooded creatures before warm blooded 4 chambered hearts. Lizards before mammals. Fish before amphibians. Etc. Also paleontologists find transitional fossils. Fish with robust fins/simple legs. Bats with wings but no echolocation abilities. Reptiles with feathers and bird-like pelvises. Apes that stand upright, but can't speak. The record is, while not abundant or overflowing with these fossils, filled with examples of "missing links."

Physics: C-14 dating, Potassium Argon Dating, Thermoluminescence, etc. etc. Additionally with astrophysics: the speed of light (ties into the Astronomers), and all of their work with an old universe. I'm no astrophysicist, so I'm hardly qualified to take up their torch, but it's fairly apparent that they don't think the universe was created a couple millennia ago, and have their own science to prove their observations. Just remember that the work of physicists allow your cell phone to work (imagine if light didn't travel at a constant...how would your conversation be transmitted if some words were transmitted at different speeds than others? Or if part of the data didn't travel the same speed as the rest resulting in a garbled signal). Nuclear power, the atom bomb, cell technology, satellite communications, lasers, the list goes on. I guess the Yecs would like to keep a couple of Physicists in the closet hidden away to keep all that stuff working.

Zoology: Okay, it's hard to separate them from biologists. But I just had to have a Z in here as well. A-Z and all that. Zoologists, thanks to cladistics, link animals based on their relatedness. Dolphins and whales belong to the same Order, Cetacea, because they are related. Not because they're roughly physically similar, built off a similar model by some creator, but because they share common ancestors. (I think ~ 50 million years ago). If physical similarity were the only requirement it would be Elephants and Rhinos that would be the Hippopotamus's closest relative, not the whales and dolphins.

So, in the last 20 minutes and off the top of my head that's a quick list of all the groups of science that are "at war with Christianity." Of course no such war exists...there are many Christians who are scientists, and believing in a biological ancient origin of our planet in no way means you can't have faith. But apparently, according to the Yecs, all these branches of science are evil. The only "war" is to keep your damn ignorance out of the scientific discussion. If and when you have a scientific, sound, reviewed, experimental observation that you can present in a civil manner in keeping with the rules of academia, you are more than welcome to come on in. Dissent is welcome and essential to the scientific process.

Is it any wonder that when we elect a fundamentalist Christian to the highest office that our science budget gets slashed? And I mean for all science, not just evolutionary biology or paleoanthropology. Is it a shock that suddenly scientists encounter a hostile environment that doesn't appreciate their contributions, their intellect, and the benefits they offer our country?* Is it any wonder that other nations close the gap that at one time put us head and shoulders above the rest of the world when it came to science, technology, and the production benefits of both?

In our country, "science" has become a bad word. As if they are trying to ... I don't know what. Seduce our children and make them become gay pedophiles who sodomize animals while burning the American flag. I guess that's what we want... Visiting a cave in Missouri a tourist asked the park guide how old the cave was. She smirked and looked at the other guide and said "Well, if you believe the scientists..." You know what, screw you. If you don't want electricity, medicine, a thriving economy, a technological edge over the rest of the world, or a strong dollar...you don't have to "believe the scientists."

Look, science is no magical happy unicorn that will fix everything and make the world a better place for ever and ever. It can be used to do terrible things, at the risk of Godwinning my entire entry, one needs look no further than the 1930's in Germany for an example of this. But science itself is not inherently evil. That was science being used for evil. It wasn't the science that was making decisions in the Reichstag. And just so you don't think I'm too full of myself: it is also not inherently good. It is simply a means at which we can gain understanding and control over the world that surrounds us.

A perfect example is nuclear physics. The split atom is neither good nor evil. It has the potential to either create clean, inexpensive, nearly unlimited power to the world...or it can be used to terrorize the world, vaporize innocents and poison the land for generations. Does that make the scientists working under the football stadium at the University of Chicago good men or evil men? Perhaps they were both good and evil at the same time...and until their work is used by the world they are simultaneously good and bad. Kind of like a cat in a box...alive and dead until you open it to see.


*Case in point, NASA was studying a supernova that had gone off, and were preparing to release their report. Doing good science, observe, document, publish for scrutiny and education. The white house controller (I can't remember the exact name of the position...PR something or other probably) told them not to release the report. Why? It dealt with the death of a star, and our sun is a star. And the thought of our own star dying some day would be a downer...and the American people don't need to think about that. Wow, no one tell them about cancer...that's such a downer it makes people cry! Someone stop those damn depressing scientists from writing about it!

Undead Naked Archaeology

Coming Soon To A Theater Near You

living the dream my friends...living the dream

So I had a pretty intense and detailed post ready and prepped to put down here today. But when I woke up I received a phone call from Gray and Pape concerning my employment. More specifically they had a job opening they'd like me to take...starting yesterday. So I'm springing into gear, cleaning my equipment, sharpening my trowels, oiling my boots and heading out to Frankfort Kentucky for the next couple weeks and then up into Indiana. It's a phase III site, Fort Ancient culture, pretty sweet. Should be if not a cake walk at least really interesting and exciting. I'd best leave soon so I'm not totally bogged down in traffic...

God I love my job.

Bears mothafucka. Bears.


So, I'm updating just to update. I feel that it's been a while since I did so, and I don't want you all to think that I'm a bad and lazy person. Don't get me wrong; I am a bad and lazy person, I just don't want you to think it.

"But Marcus," I hear you cry out, "Now that you've said that you're a bad and lazy person of course we're going to think it!"

Probably not. More likely your instinct was "No Marcus, you're not bad and lazy!"

And so I win. I am bad and lazy (doubly bad for manipulating you into thinking I'm a good and not-lazy person).

I wonder what our ancestors would think of the internet. Here we have an incredibly powerful tool* and we use it as a toy, posting lolcats and videos of guys getting hit in the nuts. Let's be honest, we all love a good nut-smash video. Instead of breaking down cultural barriers, learning about our cousins in Africa or Asia while teaching them about us...we look at naked boobies or virtually teabag 11 year olds in Halo. But then again that little punk had it coming...spawn camping whore.

I'm sure we could move them past thinking it was a devil box, witchcraft, magic machine** and at least explain what it does...if not how. What would they use it for? (I mean after exploring the depths of pornography) I'd love to watch Plato, Chaucer and Disraeli making and laughing at the latest lolcats. What historical figure's lolcat would you want to see?

*arguably the most powerful tool in the history of mankind. Why more powerful than say the atom bomb, or the internal combustion engine? Well this is a tool for communication. Total, unbridled free communication. I think it has been demonstrated fairly well that among the things that make us "human" and not just another animal is our ability to communicate. To convey abstract thoughts and ideas. To teach and learn using this amazing technique. That is what makes us human...we don't have to discover levers, the wheel, or the internal combustion engine on our own. We can take what others have learned, utilize and expand it...always progressing (so long as the communication with the past is upheld. When you lose that communication, like when literacy rates fall, you get the Dark Ages...only in the last couple centuries have we matched and surpassed the knowledge and technology of the Hellenized world).

**Okay maybe not that one...I'm sometimes pretty convinced that my computer is magical. I can't wrap my head around how it, or the internet, actually work. How did that happen? Magic.

Wanderlust


The itch struck me again...

So I'm off into the blue yonder once more. Quit my job in Missouri and am sending out my CV, hopefully I'll get a gig in Indiana that a buddy sent my way.

Apparently this sort of lifestyle is "so freaking weird." I dunno, it seems pretty normal to me. I just go where the work is, moving whenever I feel antsy, bored, superfluous, or just want a change of scenery. Can't everyone do that?

Well, no. I understand that, and I'm very grateful that I do have this sort of freedom. But on the other hand, it just seems very natural. Because of all the rain the project in Missouri is trickling on, but there isn't really enough work to keep all 18 of us occupied. They hired a massive crew trying to knock out 3 sites on a certain Billy Shepard's field by April first...the idea being to pile bodies on to meet a stupid deadline he imposed (he isn't too keen on the pipeline, and us, being on his property). It would have worked too...if it weren't for those meddling kids...rainstorms. I meant rainstorms. We lost so many units due to rain, put on hold or actually ruined, that we've got at least another week on his property waiting for them to dry out...but we've only been able to work on one or two pits at a time, which means 10 people or so standing around trying to do a 2-4 person job.

Blech, it's just so frustrating. The cold and wet don't help...but it's the useless puttering around, busy work, the total inefficiency that started my wandering itch this time. Paul's email came just as it started to get bad, so I've leaped at the chance and walked away, hoping once more I'll land on a good gig.

There's good work to be done out there, and I want to do as much of it as I can, see as many places...artifacts...cultures as possible, do as much archaeology as I can. I figure I've only got 50 years or so left (1/3 of my time is gone!) no sense in wasting time, right? Some people want families, and that's awesome. I'm serious, despite all my sarcastic comments to the contrary. If that's what will fulfill you, make you happy, scratch your brain...by all means do it. That just isn't my shtick, I need to explore, figure out what's going on out there. So I'm going to. I'm taking a week or so to regroup, resupply and clean my equipment, then head on out. It's amazing how fast time goes...and how much left there is to do.

Angry noises

So, I posted a bullshit filler on Monday, and nothing yesterday. Why? Because I'm really grumpy.

It just. Keeps. Raining.

Of course it is spring, and it is supposed to rain. I mean duh, that's what spring is all about, without rain the plants wouldn't bloom, the crops wouldn't grow and all that. But I am not a plant, and neither is archaeology.

I can hear the protests "But Marcus, that stuff has been there for a thousand years, getting flooded into, what's one more rain drop gonna do?"

Oh I wish.

Unfortunately when we open a unit we expose any features or fragile artifacts (here it's mainly pottery) to the elements, instead of being protected by feet of dirt. We lost one potsherd when it we exposed to open water as our unit flooded...it just disintegrated. Poof gone. We've pulled out water pumps, and they aren't really that helpful. Sure they'll pull out the foot of water that flows in over night, and we even dug little sump wells so that the water drains there instead of the floor. The problem is that the pump will get all the water and then start sucking air, which will burn out the impeller. So we turn it off. Then the unit floods again 5 minutes later, so we turn it on...work a little...and then repeat the whole process as water oozes out of the floor, through the walls and out the sump well. This makes the floor a mucky mess, which in order to excavate we need to stand on...churning up the muck. Any features (which are signs of cultural activity usually visible as dark stains) are obliterated. It's terrible.

We have so few pits that are digable (well...none of them are really, just some that don't have much information so we just chunk them out as quickly as possible to give it a good faith effort) that people just sit around or pile onto a unit needlessly. Today we had like 12 people excavating one pit. Okay, I lied. We called the pit done and were just running an auger to 4m to do a quick and dirty sample. Not the work of 12 people...3 at most. Hooray. Perhaps next time I'll explain the differences between the phases of archaeology and why this so bad. But for now, trust me, it is bad. Bad archaeology, bad weather, grumpy people, bad news bears.
