(The final assignment for my archaeology class is to come up with an outline for a unit on a topic which was not already covered in the course. Here's my offering.)

After taking courses in both genetics and archaeology, I have become quite interested in research incorporating both. Genome mapping is one of archaeology's newest tools, and the information gathered in this way is fascinating.

Lecture 1: The Genome Treasure Map: GATC Marks the Spot

Genome mapping is being used as a sort of snapshot to study disease and heredity in long-dead people. So far, it has been used to learn more about only a few individuals and groups of people, but use of this tool is rapidly becoming more popular. The elite group of people whose genomes have been mapped includes a Spanish hunter gatherer, a Greenlandic Inuit, some Neanderthals, a Denisovan, Richard III (1), and Otzi the Iceman. Databases have been constructed for the genome sequences of Neanderthals (2) and Denisovans (3). With this technology, it may possible to determine characteristics of other extinct, ancient humans, too. One such group would be Homo floresiensis, the so-called "Hobbit" people of Indonesia (4).

The lecture would include the following basic information:
- what is genome mapping?
- how is DNA gathered from human remains
- what can be learned from this technique
- what has been learned about the people studied in this way

Recommended readings include:
- 'Startling and shocking': Key figures in the search for Richard III recount their reactions to the discovery of a skeleton at Grey Friars: http://www2.le.ac.uk/offices/press/media-centre/richard-iii/old-content/features/startling-and-shocking
- Richard III DNA tests to reveal hair, eyes and diseases of the King: http://www.culture24.org.uk/history-and-heritage/archaeology/art467401-Richard-DNA-tests-to-reveal-hair-eyes-diseases-King

Lecture 2: The Relationship Between Hunters/Gatherers, Farmers, and Animals

As for a second lecture topic, we have other uses of genetic research in conjunction with archaeology to investigate. The genetic records of domesticated animals and crops reveals not only information about the animals of the time, but also as to the prehistory of farming and domestication. This blurred line between wild animals and domesticated ones potentially shows a blurred line between hunter/gatherers and farmers. Recent genetic studies have demonstrated that hunters/gatherers coexisted in geographic areas with farmers.

The lecture could include:
- What genetic studies of animals reveals about people's prehistorical relationship with animals
- The relationship between farmers and hunter/gatherers as determined by genetic research
- What plant genetics tell us about domestication of crops

Recommended readings include:
- The story of animal domestication retold: http://www.geneticarchaeology.com/research/The_story_of_animal_domestication_retold.asp
- How Farming Reshaped our Genomes: http://news.sciencemag.org/archaeology/2014/01/how-farming-reshaped-our-genomes


Related Exercises:

1. What other ways has genetic research been used in archaeology?
2. What ethical concerns are there with the genetic testing of human remains?

Your answer should be should be between approximately 400 and 750 words (with 750 as a maximum).

I grew up eating a lot of food traditional to my Canadian ancestors. We rarely purchased pre-made baked goods, and my mother baked almost everything from scratch. My family were gatherer/hunters, and much of our food came from our farm or from the wilds. I grew up cooking on wood stoves and over campfires with wood we gathered with our dog or pony teams, so I suspect my understanding of foods differs from that of people from urban, western upbringings. I was once used to cooking and baking in the ways my ancestors did over the past couple of hundred years. Although I now cook with modern implements I find the food tastes quite similar as long as I'm using comparable ingredients.

A while back, I picked up a copy of Dorothy Duncan's Nothing More Comforting: Canada's Heritage Food. It contains a variety of recipes similar to the ones I grew up with. I chose a recipe for honey bread because I had all of the ingredients in my larder already. This recipe was first published in 1896 in Fanny Merritt Farmer's The Boston Cooking School Cook Book. It was only about this time that honey was first listed as an ingredient in recipe books. Before that time, honey was served as an accompaniment to scones, tea, and such.

The recipe is as follows:

2 cups flour
1 teaspoon baking powder
1 teaspoon soda
1 teaspoon salt
1/2 teaspoon cinnamon
1 teaspoon ginger
1/2 cup strained honey
1 egg, lightly beaten
1 cup milk

Mix and sift dry ingredients. Add others. Beat thoroughly. Bake in loaf or bread stick pans in moderate oven, 350*F. Makes 1 loaf.

These would have been staple ingredients in a Canadian larder around the turn of the 20th century, available from the local grocer. The fresh ingredients such as honey, eggs, and milk, were produced on many farms, and flour was available from grain mills.

If you're familiar with baking, you may notice that a cooking time isn't listed. Neither does it say if the pan should be greased or powdered. I made the guess that I should cook it for about 45 minutes, as that's about how long it takes a gingerbread loaf to cook. I also lightly greased the loaf pan with butter.

About ten years ago, I studied metal arts at craft college. My focus was in the creation of jewellery and other small metal objects. I studied the history of jewellery as part of my curriculum, and we learned about ancient techniques. One of the techniques we studied was granulation. Granulation is a technique in which tiny, uniformly-sized beads of metal are affixed to a metal object in a pattern.

The early masters of this art were the Etruscans, back in the third century BCE. The precision work and the infinitesimal metal spheres they created are mind-boggling. Extant pieces show granules a mere 0.14 mm in diameter (1). It is unknown how such tiny, consistently-sized beads were created. It is also unknown how they were attached to metal pieces without melting them. Probable techniques have been determined, but there is no hard proof that these techniques are the ones which were actually used.

This photo shows detail on an Etruscan earring demonstrating a variety of granulation sizes and patterns, as well as a variety of other techniques including filigree (fine metal scrolling), chasing (hammering to create a concave surface design), repoussage (hammering to create a convex surface design), and dapping (hammering a flat piece of metal into a dome).

Long before archaeology was ever called archaeology, there were people going around searching for historical artefacts. In particular, people sought out holy relics. A holy relic is a part of a venerated person, or a piece of an artefact associated with that person. Although many of the relics are fake (it's been said there were enough splinters of the True Cross to build an armada), these fakes were still items of import. In medieval Christianity, "the physical remains of saints and holy figures were considered an essential part of the faith, offering a powerful connection with Heaven" (1). Pilgrimages to holy relics were vital, and could be used as Indulgences to cut down on time languishing in Purgatory. The most important relics of all were the ones associated with Jesus Christ. Since he was believed to have physically ascended to Heaven, the opportunities to retrieve a piece of Jesus were slim, and limited to hair, blood, fingernail clippings, or his foreskin.

At one point in history, there were a reported eighteen foreskins of Christ floating around Europe. Barring some loaves-and-fishes-style miracles, it is obvious these can't have been real. Even if the foreskin of baby Jesus had been saved, such a tiny scrap of organic matter should have rotted away while he was still an infant.

Regardless, the relic(s), called the Holy Prepuce, got around. Determining the veracity of these relics was vital, and specialists arose. The most common testing method was a taste test. "A properly trained physician chosen by the local priest would chew the shriveled leather...to determine whether it was wholly or partly human" (2). When Pope Innocent III was called upon to pass judgement on the authenticity of one Holy Prepuce, he demurred (3). I can't say I blame him.

One such Holy Prepuce was personally delivered by an angel to Austrian nun Agnes Blannbekin in the thirteenth century (4).

"Crying and with compassion, she began to think about the foreskin of Christ, where it may be located [after the Resurrection]. And behold, soon she felt with the greatest sweetness on her tongue a little piece of skin alike the skin in an egg, which she swallowed. After she had swallowed it, she again felt the little skin on her tongue with sweetness as before, and again she swallowed it. And this happened to her about a hundred times. And when she felt it so frequently, she was tempted to touch it with her finger. And when she wanted to do so, that little skin went down her throat on its own. And it was told to her that the foreskin was resurrected with the Lord on the day of resurrection. And so great was the sweetness of tasting that little skin that she felt in all [her] limbs and parts of the limbs a sweet transformation" (5).

Since people have been making dick jokes for thousands of years, much to the displeasure of the Catholic Church, the topic of the holy foreskin was a source of ribaldry. By 1900, they'd had enough of it, and it was decreed that talking about Holy Prepuce was an offense punishable by excommunication.

By the twentieth century, there was only one known holy foreskin, anyhow. It resided in Calcata, Italy. "For more than four centuries, the 'Holy Prepuce' had been the city's treasure, kept behind bronze doors over the altar in the Church of the Most Holy Name of Jesus. It was displayed every year on Jan. 1, the Feast of the Holy Circumcision", finally vanishing in 1983 (6).

Where did this relic end up? There are numerous speculations. Considering the fate of an earlier Holy Prepuce was transmogrification into the rings of Saturn (7), the hypothesis that it was reclaimed by the Vatican is quite reasonable (8).

My next archaeological homework assignment is a fun one. I pick an archaeological site, provide some clues, and you get to see if you can guess where it is. Here goes!

This archaeological site is a tranquil seaside location, and until it was visited, no artefacts were on site. Despite the lack of both artefacts and ecofacts, 21.5 kg of materials were brought back by explorers for further investigation. The visit itself is what established this as a unique archaeological site.

The following is an aerial view.

In August of 2012, the search for Richard III's remains began, and on the very first day of the dig, his body was discovered underneath a car park in Grey Friars, Leicester (1). I've kept half an eye on this story for a while. Richard III is a fascinating character, and the eponymous play is one of my favourite works by Shakespeare.

The story just became even more interesting for me. An article in Culture24, Richard III DNA tests to reveal hair, eyes and diseases of the King, shows that the genomes of Richard III and one of his proven descendants will soon be mapped. Richard III is lumped in with a Spanish hunter gatherer, a Greenlandic Inuit, some Neanderthals, a Denisovan, and Otzi the Iceman as an elite group of historical/prehistorical figures whose genomes have been studied (2). The story gains publicity because Richard III is a character who captures people's imaginations, because his ignoble resting place beneath a car park seems so anticlimactic, and because the Human Genome Project is a new and exciting area of scientific research.

The article emphasizes the role of DNA in our sense of identity, and how understanding the king's genetics gives us a snapshot of disease and heredity in the fifteenth century. The article, however, is brief and does not go into any real depth. As a result, it raises more questions than it answers. Just how prevalent is genome mapping in archaeology? The Human Genome Project was launched in 1990 (3). How soon afterwards until it was used as an archaeological method? A cursory internet search for genome mapping and archaeology reveals a wide range of results, and they're not all related to human remains. There are plenty of articles which discuss genome mapping in molecular archaeology (eg. Molecular archaeology of the Escherichia coli genome (4)), as well as other studies of ecofacts versus human remains and artefacts (eg. Plant genome archaeology: evidence for conserved ancestral chromosome segments in dicotyledonous plant species (5)).

The article also raises questions about the other people listed whose genomes have been mapped. It contains no links to these studies, which seems like an obvious oversight. Fortunately, another online search reveals more information. I discovered that just as there is a Human Genome Project, there is a Neanderthal Genome Project. You can even search through the data at The Neandertal Genome (6). I learned that Denisovans, a lesser-known peer to Neanderthals and prehistoric humans, may be the first non-Neanderthal archaic humans to be sequenced (7). The genome mapping of the ancient Inuit in Greenland "provides evidence for a migration from Siberia into the New World some 5,500 years ago, independent of that giving rise to the modern Native Americans and Inuit" (8). The study of Otzi the Iceman's cellular mitochondria reveals mutations no longer present in our population, suggesting he belonged to a now-extinct group (9). Lastly, the study of the Spanish hunter-gatherer may help explain why prehistoric hunter-gatherers could coexist with farmers for thousands of years before disappearing (10). This is just a tiny cross-selection of the extant information on these people.

The archaeological data recovered through genetics studies is vast. I never would have suspected that a reviled British king would be the one to demonstrate this to me.

We cannot escape the past. Everything we touch and see is from the past. Our present is so fleeting that it has left us before we have even become aware of it. The question of who owns the past is misleading, for the past owns us. All we can do is create and imagine based upon what it gives us.

For this project, I chose to put together an assemblage art piece composed primarily of found items. I decoupaged an old spice rack with a variety of images, from alchemical symbols to palmistry diagrams to paintings and photographs. I added ribbon and aged its appearance with ink. I incorporated a collection of old bottles that I hand-coloured, giving them a more historical appearance than they'd had initially. An engraved drinking horn, a collection of handmade rose beads, a stone goblet, a turkey vulture feather, a ceramic incense burner, and a collection of papercraft and woven boxes rest atop tapestry-style fabric. I intend for the collection to look like artefacts and moments out of time which hide secrets.

This was my first attempt at making a webcast, and my last assignment for my archaeology course. The video's a bit clunky, but I hope you find the story interesting. If my video editing skills were better, there'd be much more audio. I did all the photography and videography here.

When I was about four or five years old, I was hard at work at my grandmother's house in Fredericton, NB, making mud pies. I had a few implements: a saucer, a bowl of water, bucket, trowel, and rake. I had already picked a bunch of the brilliant red berries which grew on the deadly nightshade vines growing rampant, and now I was digging away at the dusty ground collecting "flour" for my cakes. Although I'd made mud pies many times in the past, this time I decided to dig a deeper hole than ever before.

That's when I started finding things.

The first strange thing I found was a bone. I wasn't sure what sort of bone it was, but it looked like it might be from a chicken leg. This was strange. Normally, the ground only offered up such things as rocks, worms, and ants rushing to carry away little white oblong eggs that I'd unearthed. I'd never found a chicken bone before. That's the sort of thing normally scraped off the plate into a compost heap. It was discoloured. Pleased with my find, I ran up to show it off to my grandmother. She made me throw it in the garbage and wash my hands.

After I'd done this, I ran back down to the backyard and kept digging. In a lower stratum, I found something inorganic, faded, and red. Curious, I kept digging, and finally I'd pulled up my greatest archaeological find, yet: a chewed-up rubber dog bone.

Why was a dog bone underground? Although my grandmother had a dog, I knew this hadn't been one of its toys. I took the artefact back to my grandmother, and once again, she made me throw it in the garbage and wash my hands.

I dug more, afterwards, but I didn't find anything else of interest in the soil. I celebrated my great find by finally finishing my mud pies.

Now, several decades later, I'm studying archaeology again, but this time, my grandmother isn't making me wash my hands.
