Humans are always interested in the past. A 5th century Thracian princess liked to collect stone axes and was buried with a lot. Now excavations are a lot more careful and you can learn more from what’s found. Archaeology is a sub area in anthropology. In this little VSI, you get a very good picture of the discipline.
What do archaeologists do? Study excavated remains and objects. These are varied and interesting: the example of 138 watermelon seeds in the wife of Marquis of Dai in 2nd century BC; the analysis that shows some sort of rice wine made in 9000 years ago; chemical analysis of teeth can suggest in what climate a person grew up; and the Iceman with frozen sperms that many women volunteer to be impregnated with. By and large, there isn’t a lot of new excavation as there’s too much backlog. The only exception is salvage excavation at construction site and the like. Looting is a big enemy. In some cases there is a different challenge: some (e.g., militant ultra-orthodox Jews) violently resist any excavation due to desecration of graves.
What kind of tools do they use and what kind of work? Techniques are improving: Chemical dating for bones and Electron Spin Resonance can stretch dating back to 100 kilo-years ago (kya). A South African cave of Australopithecus remains was identified as promising by analysis of Google Earth. But some times it’s less high tech: Archaeologists will copy stone tools, use them to study wear patterns.
What can they teach us? They can tell us a lot about the past.
• Cognitive activities: Archaeologists can tell that deliberate burial happened some time 100-40kya. Judging from the pollen on the body, there were flowers with the burial. A figurine dated 230kya shows under microscopic analysis to be man made art object clearly suggesting cognitive activity. There is now grudging acceptance of stone henges to be some sort of calendar device. Overall, such “cognitive archaeology” can provide some valid assessments of mind long vanished from the earth.
• Social structure: Ancient societies are loosely categorized into 4 types based on size: band (<100 ppl), tribe, chiefdom (5-20K), and state. Stonehenge is estimated to cost 30 million man-hours and clearly suggests some form of chiefdom.
• Ancient technologies: Their study of ancient agriculture practices in Nabotene and Bolivia helped revive these techniques to make life better than otherwise.
What are archeologists like? Here, you’ll find some pretty funny (at least to me) description of the lot. A few extensive quotes are in order:
“Conversely, the degree of territoriality, bitchiness, backstabbing, and vicious infighting for some reason goes way beyond what is normally encountered in other disciplines. There are inevitably a few archaeologists who are pompous, hypocritical, dishonest, pretentious, self-promoting, and unprincipled, but that does not stop them doing well in the profession.”
“…much theoretical archaeology simply consists of techniques to find unsurprising answers to obvious questions which nobody had the time, tools, or inclination to ask before.”
