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.

The end of the line for Egypt Baladi?

The controversy over the Egyptian pig cull is turning very nasty.

There are estimated to be more than 300,000 pigs in Egypt, but the World Health Organisation says there is no evidence there of the animals transmitting swine flu to humans.

Pig-farming and consumption is concentrated in Egypt’s Coptic Christian minority, estimated at 10% of the population.

Many are reared in slum areas by rubbish collectors who use the pigs to dispose of organic waste. They say the cull will harm their businesses and has renewed tensions with Egypt’s Muslim majority.

The Domestic Animal Diversity Information System hosted by FAO records only one pig landrace in Egypt, called Egypt Baladi, from بلاد which just means land or soil. “Baladi” means something like “of this land”. The pig has a long history in Egypt, but I can’t find any information on its genetic affinities. If the total cull goes ahead, will a unique, ancient landrace be lost forever?

A little little barley goes a long way

Like I say, not a day goes by. Yesterday, ramie. Today, little barley. As in:

They likely ate sunflower, marsh elder, two types of chenopod—a family that includes spinach and beets—and possibly squash and little barley, according to the findings. The people also grew bottle gourd to make into containers.

That would be the Riverton people living three thousand years ago along the Wabash River in present-day Illinois.

The Riverton crops may have “added to what was [already] a successful life” for the ancient Americans, said Brian Redmond, curator and head of archaeology at the Cleveland Museum of Natural History in Ohio.

Yes, because…

…[b]efore they began farming, the Riverton people lived among bountiful river valleys and lakes, apparently eating a healthy and diverse diet of nuts, white-tailed deer, fish, and shellfish, the study says.

So the Riverton people were not reacting to some environmental stress as a matter of survival when they became agriculturalists, but rather “engaging in a bit of gastronomic innovation.” Good for them.

Where are the peanuts?

Another splendid Moche tomb has come to light: the finery buried with the Lord of Ucupe is said to be even more impressive than that of the Lord of Sipan. According to the archaeologists, “it’s unheard of to find so many precious funerary ornaments in a single Moche tomb.” Alas, no sign of the wonderful gold and silver necklace and earrings in the shape of peanuts (groundnuts) which graced the mummy of the Lord of Sipan.

I talked about this with our resident peanut expert David Williams and he said he expected that the excavators will have “found some jars full of actual peanuts as part of the all the stuff included in the burial; it’s very common in Moche tombs.” There is a theory, he explained, that peanuts were associated with death, the journey to the afterworld and reincarnation.

When planted, the peanut grows and flowers above ground like any other plant, but then it buries its fruit underground, where it germinates, returning back into the “world of the living”, growing and flowering and burying its fruit, and so on and on, for generations (or incarnations). Plus, the peanut shell is like a little coffin. Peanuts, because of their high protein and caloric value, as well as their lightweight, durable “packaging”, make great travel food, particularly for the long journey to the afterlife.
