Preliminary report on the vent sealing project

[Dec 4] After this mornings fairly steady drenching rain there appears to be some progress with the leaks. The leak resulting in the stream across the floor shown in the photo here on November 15th seems to be fixed. But the other one under my desk / aft of the shower leaked just a tiny bit. I'll have to reserve final judgement on the one by the door until after a heavier rain or two but the other one obviously needs further attention. Darn these things are elusive!

Teosinte and the Improbability of Maize

The ancestors of wheat, rice, millet, and barley look like their domesticated descendants; because they are both edible and highly productive, one can easily imagine how the idea of planting them for food came up. Maize can't reproduce itself, because its kernals are securely wrapped in the husk, so Indians must have developed it from some other species. But there are no wild species that resemble maize. Its closest genetic relative is a mountain grass called teosinte that looks strikingly different - for one thing, it "ears" are smaller than baby corn served in Chinese restaurants. No one eats teosinte, because it produces too little grain to be worth harvesting. In creating modern maize from this unpromising plant, Indians performed a feat so improbable that archaeologists and biologists have argued for decades over how it was achieved. Coupled with squash, beans, and avocados, maize provided Mesoamerica with a balanced diet, one arguably more nutritious than its Middle Eastern or Asian equivalent.
