I blogged some time ago about a new project at the University of Manchester to document Pharaoh’s herbal medicines, but there was not much detail in the press release I quoted at the time. Now there’s a much fuller article on Discovery. It seems that the ancient Egyptians were martyrs to constipation.
Before Columbus
There’s quite a debate going on about what the Americas – and in particular the Amazon – looked like before Columbus arrived. This has been the subject of a bestseller entitled 1491, whose main arguments are summarized by the author, Charles Mann, here. It is always dangerous to simplify academic controversies as being between two diametrically opposing camps, but I’ll do it anyway. One side thinks that population levels were high in the Americas in pre-Columbian times, and that even the Amazon was essentially a gigantic, closely managed orchard, hence talk of the “pristine myth.” The other side thinks that the real myth is that of a large, widespread human population in the Amazon. This has important practical implications because, inevitably, some have seized on the debate to argue that the Amazon could be more heavily exploited today, because it was in the past.
Coincidentally, there are stories today which summarize papers coming down on opposing sides of this argument.
According to this piece, Dolores R. Piperno of the Smithsonian Tropical Research Institute in Panama and National Museum of Natural History in Washington, DC, “found evidence of widespread fire use for land-clearing by pre-Colombian populations in Latin America” when she reconstructed vegetation patterns and fire histories from pollen, phytolyth and charcoal records.
Noting the vast body of research indicates the existence of large, dense, sedentary populations in the Amazon, Piperno implies that conservationists should come to terms with the fact that tropical forests have been cleared in the past as they are being cleared today, and then move forward with effective strategies for preserving what remains.
A different view emerges in this discussion of the work of Mark Bush of the Florida Institute of Technology in Melbourne. He looked at charcoal and pollen records at two Amazonian lakes and found that
…rather than being widely dispersed, people living in the Amazon most likely clustered near the good places, and that overall population numbers were likely not as high as the top estimates of pre-Columbian people.
This will run and run.
Starch grains and the origins of agriculture
A couple of papers discussed here and here (among other places: the chili pepper story in particular has been getting a lot of media coverage) describe how the minute, species-characteristic starch grains found in micro-crevices on stone tools and cooking utensils recovered from archaelogical sites are being used to study the domestication of crops as varied as maize, cassava and chilies in the Americas. The findings are pushing back the timing of domestication and suggesting that wet lowland areas were more important in the process than previously thought. Jeremy blogs on the chili angle at greater length here. No word on the past of cactus cultivation, at least in these papers, but this piece suggests its future may be troubled.
Amazing maize stories
Apparently, maize recovered from ancient burials in NW Argentina is genetically “almost identical” (whatever that means!) to the landraces still being grown in the area. I wonder if it was prepared in the same way too. This piece in the Washington Post certainly shows that maize culinary traditions are strong, and can go back a long way.
What did Neanderthals eat?
Recent media reports that Neanderthals were occasional cannibals and that women may have accompanied the men on their hunts got me thinking about the Neanderthal diet in general. In particular, did they eat much in the way of plant products at all? While meat was clearly the mainstay of the diet, it does seem from this interesting rebuttal of the hunting women hypothesis that: Â
Vegetable foods may well have been part of Middle Paleolithic diets in Eurasia, but these were more like salads, snacks, and desserts than energy-rich staples…Large underground storage organs are common among plant taxa in arid sub-Saharan Africa, but the high-yield edible plant foods of temperate and Mediterranean Eurasia tend to be seeds and nuts that, while potentially nutritious, require more effort to collect and process and thus afford low net yields (Kuhn and Stiner 2006:957).
Wouldn’t it be great to be able to promote some underutilized nut as a Neanderthal dessert? Or perhaps that would not be such a clever idea, given that the Neanderthals died out… Anyway, although some of the information sources listed seem somewhat suspect, there is a compendium of internet resources on the “paleolithic diet” here.
