The slow march of domestication
Kris’s Archaeology Blog at About.com has a short post summarizing recent work which suggests that there may have been a gap of a millennium between domestication of, and dependence on, broomcorn millet (Panicum miliaceum) in China — and similar gaps for a number of other crops in different centres of origin.
What this is telling us, is that hunter-gatherers took the initial steps towards farming many generations before their descendants became dependent on domestic crops. Interesting, don’t you think?
Indeed.
Penis pepper finally reveals its identity
A weird, comma-shaped fruit is often to be seen “floating over the soldiers marching off to be sacrificed or flying priests” in the artwork of the Moche, an agricultural people that frequented the coastal plain of northern Peru from A.D. 100 to 800. That’s been recognized since the 1930’s, when archaeologists gave it the name ulluchu — meaning “penis pepper” because of its shape — but without actually been able to say what the fruit was. Modern-day Peruvians just don’t recognize it, and botanists need more to go on for a scientific identification.
They got it recently when the actual remains of a fruit were found during excavation of the the tombs of Dos Cabezas in the ancient Moche city of Sipan. Ethnobotanists Rainer Bussmann and Douglas Sharon had been asking around for ulluchu for years:
“We would go to these markets and people would say, ‘We think we know what that is, but it’s not being sold here,'” said Sharon, the retired director of the Phoebe A. Hearst Museum of Anthropology at the University of California-Berkley. “Well, one of the reasons it wasn’t being used is because the Ulluchu seems to show up during sacrifices. And no one is being sacrificed anymore.”
But armed with the physical specimens, desiccated as they were, Bussman, who works at the Missouri Botanical Gardens, eventually homed in on the genus Guarea, which is in the mahogany family, not the pepper.
“Rainer is a first-rate taxonomist,” Sharon said. “He studied every physical characteristic of these plants until he was absolutely certain we had it.”
Guarea seeds contain hallucinogenics and chemicals which raise blood pressure. Both would have been useful in sacrifices.
Bussmann, director of the garden’s William L. Brown Center for Plant Genetic Resources, plans to further study the plant’s chemistry and suspects it might have applications as a blood pressure and erectile dysfunction treatment.
The sacrificial soldiers in Moche artwork over which ulluchu fruits float often appear to have erections. Expect huge plantations to spring up in the Peruvian lowlands.
A new use for tubers
A sharp knife is an essential element in the preparation of many vegetables, a fact as true 2 million years ago as it is today. Results from the recent meeting of the Paleoanthropology Society, reported in Science, indicate that the people who occupied the site of Kanjera South in Kenya carried stones that held an edge better from at least 13 kilometres away. Thomas Plummer of Queens College in New York and David Braun of the University of Cape Town found that a third of the stone tools at Kanjera came from elsewhere, and that these stones made longer-lasting knives than local material.
What were they using the knives for? To butcher animals, obviously, but also to cut grass and to process wild tubers. Cristina Lemorini of La Sapienza university here in Rome showed that the pattern of wear on the ancient tools matched the wear on modern stone tools used by the Hadza people of Tanzania to process plant material. In particular, using the stone knives to cut the underground storage tubers of wild plants left a pattern of grooves and scratches that was identical on modern and two-million year old stones.
Why tubers? There have been lots of theories about the role of plant tubers in the evolution of humanity, most of which hinge on the energy to be obtained from tubers, especially when times are hard. Margaret Schoeninger, of the University of California, San Diego, floated an intriguing new idea at the meeting. She noted that most of the tubers provide scant energy, and that modern Hadza chew on slices of tuber but don’t swallow the fibrous quid. Measurements show that panjuko (Ipomoea transvaalensis) and makaritako ((Would you believe not a single instance in Google, apart from a reference to a 2001 paper by Schoeninger? At least until after today. Insert obligatory rant about common names without binomials here. And if you have a binomial, please share it, for those who come after us)) can be up to 80% water. Schoeninger thinks that early humans used the tubers as portable canteens.
That might raise the question: why weren’t they domesticated? That’s an unanswerable hypothetical, but the simple answer might be that there was just no need to.
