... of genetics and molecular medicine at Emory University and a champion of the African Eve theory. Surely an unusual illustration for the archeology section, but the DNA in these mitochondria may upset long-held theories of human migration. Anyway, Wallace has been studying mitochondria, those little energizers in human and animal cells. Strangely, mitochondria have their own DNA, which is separate and distinct from the nuclear DNA that directs other biological processes. Mitochondrial DNA has had its own history of evolution and is different for various human populations. Wallace has used this fact to trace the origins of American Indians by comparing their mitochondrial DNA with that from Asians, Africans, etc. His conclusions are controversial to say the least. The Amerinds, who comprise most of the Native Americans, arrived in a single migratory wave 20,000-40,000 years ago -- not merely 12,000 years ago! Native Siberians lack a peculiar mutation of mitochondrial DNA that appeared in the Amerinds 6,000-10,000 years ago, casting doubt on the Siberian land bridge theory. Instead, this particular mutation is found in Southeast Asia, Melanesia, and Polynesia. The Navajos, Apaches, and other so-called Na-Dene peoples entered North America a mere 5,000-10,000 years ago. The article does not say from where. (Bishop, Jerry E.; "A Geneticist's Work on DNA Bears Fruit for Anthropologists," Wall Street Journal, November 10, 1993.

(Anonymous; "Surf's Up and Up and Up," New Scientist, p. 29, October 27, 2001.) Comment. The Atlantic's waves, too, have been getting larger. (SF#113) But if you want to surf some true Pacific giants, you must leave the shoreline and head for Cortes Bank 160 miles offshore. There, far out of sight of land, lurks a shallow rock shelf that amplifies wind-driven waves---but only the largest of them. The elliptical swirls of the smaller waves do not reach down to the rock shelf and are unaffected. But when bigger swells encounter the shelf they are amplified into giants. So challenging are these waves that. when conditions are right, expert surfers boat out to Cortes Bank and wait for the really big ones. Mike Parsons caught the first wave at dawn. It was 18 metres tall and moving at around 40 knots. You can't paddle fast enough to get onto a wave like that---you have to be towed by a jet ski. Evan Slater, editor of Swell.com, did try paddling onto a wave, but had to abandon his board and dive deep underwater ...

A new BBC documentary entitled Ancient Voices proclaims that the first settlers of the New World were from Australia and Melanesia. Skulls thought to be 9,000-12,000 years old have been unearthed in Brazil with features that closely match those of Australians living about 60,000 years ago. Evidence of even earlier contacts comes from stone tools and charcoal at Serra da Capivara, in northeastern Brazil. These artifacts indicate human habitation as long as 50,000 years ago. These very early Australians, however, seem to have been exterminated by a later wave of Mongoloid invaders. W. Neves, University of Sao Paolo, has measured hundreds of skulls between 7,000 and 9,000 years old. He notes a marked change in skull shape during that period going from exclusively Australian to totally Mongoloid. (Anonymous; BBC Online Network , August 26, 1999. Cr. M. Colpitts. Comments The claimed Mongoloid invasion of Brazil jibes nicely with claims of early Chinese visits to the New World. The artifacts at Serra da Capivara support the findings of N. Guidon at Pedra Furada, Brazil -- also said to be about 50,000 years old. (SF#112, #108, #105) The three references given above are not science journals, so caution is advised.

An unusual rock fall at Yosemite created a similar air blast with severe consequences. July 10, 1996. Yosemite National Park, California. We reported this remarkable event in SF#111 for its far-flung seismic waves, which jostled seismographs at Berkeley and Reno over 200 kilometers distant. Actually, there were two rock falls 14 seconds apart. The "rocks" fell from a 665-meter cliff at Happy Isles in the eastern part of Yosemite Valley. No pebbles these; with volumes of 23,000 and 38,000 cubic meters. Although the impact area of the rock falls was not particularly large, the falls generated an air blast and an abrasive sandy cloud that devastated a larger area downslope of the impact sites toward the Happy Isles Nature Center. Immediately downslope of the impacts, the air blast had velocities exceeding 110 m/s [about 245 mph] and toppled or snapped about 1000 trees. Even at distances of 0.5 km from impact, wind velociies snapped or toppled large trees, causing one fatality and several serious injuries beyond the Happy Isles Nature Center. A dense sandy cloud trailed the air blast and abraded fallen trunks and trees left standing. (Wieczorek, Gerald F. et al; "Unusual July 10, 1996, ...

(SF#60/160) The subject then was the strange mesmerizing effect electrical equipment has on ants. They dote on airport runway lights, household electrical meters, and in particular electrical relays, where they congregate en masse. Now, a decade later, we discover that they are also not adverse to exploring microwave ovens -- even when they are turned on! We cannot explain the attraction of electrical relays, but we do know how ants survive in humming microwave ovens. It is because the microwaves inside the oven form standing waves. Energy is high in some areas -- ants would fry there -- and weak elsewhere. Ants seem to be able to find these lowenergy refuges and survive very nicely -- perhaps on the food you were planning to consume! (Anonymous; "Them!" New Scientist, p. 109, July 31, 1999. Comment.

... this wild region were evidently inspired to develop throat-singing so that they could better mimic the sounds they heard in nature: the singing of birds, the wind, the sounds of insects. Throat-songs have two components. The first is at a low, sustained fundamental pitch, which can be likened to the drone of a bagpipe. The second, superimposed on the low drone, is a succession of flute-like sounds that resonates high above the drone. It is the second component that can be controlled so as to mirror natural sounds. The result is like nothing Mozart or Verdi conceived. But it is an art form valued in Tuva and a talent rather remarkable from a biologist's perspective. One should compare the vocal tract to an organ pipe with its standing waves, except that the human pipe is only 7 inches long in the average adult male. One end of the human pipe is the mouth; the other is at the so-called "vocal folds" deep in the throat (larynx). To control their "instrument" throat-singers move their tongues back and forth to change the standing waves in the vocal tract. The source of raw sound is the vocal folds. It is the vocal tract that shapes the raw sound into musical tones. Biofeedback is also involved as the throatsingers tweak the rate and manner in which the vocal folds open and close.
