But don't uncork the champagne yet, because molecular clocks are not like Big Ben. Here's what has happened: A. Torroni and some colleagues at Emory University have analyzed the mitochondrial DNA (mtDNA) of members of seven linguistically related tribes in Central America called the "Chibcha speakers." Assuming that the homogeneous group separated from the other Amerind tribes 8,000-10,000 years ago, the Emory group found that their mtDNA had mutated at the rate of 2.3 -2 .9 % per million years. (Note: this works out to 0.0022-0 .0029% per thousand years -- a very small amount to measure accurately!) Next Torroni et al measured the mtDNA of 18 other tribes throughout the Americas and, using the mutation rate just mentioned, computed how long ago these peoples had diverged from a common ancestor. The result: 22,000-29,000 years ago. The Emory study was published in the February 1, 1994, issue of the Proceedings of the National Academy of Sciences . All this is very well, but suppose that the tribes had ...

... ." May 25, 1997. Near Loco, Oklahoma. In what might be called a "video replay" of the above phenomenon, L. Lamphere caught a similar fast-moving "object" near a tornado-spawning storm. He and his team had a digital video camera trained on the storm and were taking time-lapse still photos. Lamphere reported: "The ceiling was maybe 900 feet. We were about four or five miles from the storm, which was tracking southeast. The object was well-defined and well-lit, but was obscured briefly by scud clouds. It dipped and bobbled in its trajectory before it flew into a storm known to contain hail the size of baseballs and then reemerged, apparently undamged. "Scientists at the Astrophysics Department at the University of Oklahoma believe the object was solid and may have been traveling between 9,000 and 20,000 mph." (Anonymous; "Image on Storm Video Raises Questions," Dallas Morning News, June 21, 1997. AP item. Cr. D. Phelps.) Comment. Just one high-speed "object" might be dismissed as, say, a photographic artifact. But, when two are caught by cameras imaging violent meteorological events, we must conclude that something unusual is going on. From Science Frontiers #113, SEP-OCT 1997 . 1997-2000 William R.

There, the authorities say that, about 10,000 years ago, humans suddenly learned how to sow and harvest such crops as wheat and barley. There, civilization really began. Or was it there? Wadi Kubbaniya, Egypt. At this site, G. Hillman, of the Institute of Archeology, London, has found grinding stones and tubers. This site is dated at 17,000-18,000 years old. New Guinea highlands. J. Golson, formerly of the Australian National University, has found ditches and crude fields in this area. The implication is that humans were tending plants here between 7,000 and 10,000 years ago. Buka Island, Solomons. While excavating Kilu cave, M. Spriggs and S. Wickler unearthed small flake tools with surfaces displaying starch grains and other plant residues. Evidently, these tools were used for processing taro. Further, the starch grains resembled those of cultivated rather than wild taro. Date: about 28,000 years ago.

... We hear a lot about the endless steppes of Asia and the immensity of the Sahara, but who writes about the earth's dominant geomorphological feature? The abyssal hills are left out of the textbooks because so little is known about them. They are hidden under 3 kilometers of water. Individual abyssal hills rise 100-2 ,000 meters from the ocean floor; they are about 7-15 kilometers across; their lengths are not well known. We know them mainly from fathometer readings. If we could see them visually, they would probably look like the Appalachians from an airplane; that is, wash-board-like. Although heavily draped with pelagic sediments, the abyssal hills are believed to have been shaped by faulting and volcanic activity. K. MacDonald and coworkers at the University of California, Santa Barbara, now believe that both processes are involved: "On the basis of data obtained last January on a series of dives along the East Pacific Rise (EPR), a ridge that runs off the coast of Central and South America, researchers theorize that the linear ridges of abyssal hills, which decorate the ocean floor somewhat like ribs on a washboard, are formed by an interplay between both volcanic eruptions and faulting action."

... of Mars, with only two tiny moons to dampen its spin excursions, seems to have gone through many wild swings, as indicated in the figure. What deadly climatic changes must have wracked our sister planet! (Touma, Jihad, and Wisdom, Jack; "The Chaotic Obliquity of Mars," Science, 259: 1294, 1993. Also: Laskar, J., and Robutel, P.; "The Chaotic Obliquity of the Planets," Nature, 361:608, 1993.) Comment. The successful evolution of higher life on earth (a presumption!) therefore seems to have depended upon the gravitational shields of Jupiter and Saturn as well as the presence of our unusually large satellite. How likely is this combination of planets and satellites in the rest of the universe? Of course, life-as-we-know-it also requires just the right kind of central star and a planet with good air and water. Perhaps lifeas-we-do-not-know-it is more likely!

Science Frontiers ONLINE No. 44: Mar-Apr 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Space Spume The celestial pot seems to have boiled over "in the beginning." New surveys of the galaxies suggest that they are mostly located on the surfaces of bubbles, not as we thought for so long distributed uniformly throughout the cosmos, the expanding debris of the Big Bang. If further surveys confirm a bubbly universe, the "conventional explanations for the evolution of large-scale structure in which gravity played a dominant role may have to be modified or abandoned." To explain the bubbles, a new scenario has Big Bang #1 creating a population of uniformly distributed, extremely massive stars, which eventually burned out and exploded in a crescendo of supernovas. One stellar detonation stimulating adjacent giant stars to explode in a chain reaction. The bubble-like shock waves expanding outward from these explosions stimulated the condensations of the stars we now see in the heavens. Naturally, these stars and galaxies are concentrated on the surfaces of the shock wave bubbles. (Anonymous; "New 3-D Map Shows the Cosmos with a 'Bubble Bath' Appearance," Baltimore Sun, January 5, 1986.) Comment. The space bubbles are mapped using redshifts as measurements of distance. As all-too-frequently asserted in this book, some redshifts may not be distance yardsticks, in which case these theoretical bubbles would burst. As the structures of the cosmos and the subatomic worlds become more and more foreign to everyday experience ...

Called Stentor coeruleus, this protozoan is only 0.2 mm long and swims backward by rotating its cilia. According to the article, this is the first instance of a photosynthesizing animal. (Anonymous; "Animal That Lives on Light," San Francisco Chronicle, June 28, 1985, p. 2. Cr. J. Covey) Comment. Nothing was said about whether the protozoan also ate food in the conventional manner. If verified, this is not a trivial discovery. Of course, some plants eat meat, but animals seem to have found sunlight too weak to utilize for mobility and other energy-rich processes and activities.

No. 1: September 1977 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Animal Behavior Prior To The Haicheng Earthquake The catastrophic Chinese Haicheng earthquake of 1975 was preceded by many reports of unusual animal behavior. Beginning in December 1974, lay observers noted dazed rats and snakes that appeared to be "frozen" to the roads. In February, reports of this type increased markedly, including observations of general restlessness and agitation of the larger animals, such as cows and horses. Rats now appeared as if drunk. Chickens refused to enter their coops and geese frequently took to flight. Chinese scientists seem convinced that such animals behavior might help predict some of the larger earthquakes. Further research is being undertaken at the Institute of Biophysics in Peking and at Peking University. (Molnar, Peter, et al; "Prediction of the Haicheng Earthquake," Eos, 58:254, 1977.)

"Near the star Alfa Hydrae (see illustration) appeared a perfect bright sphere, about 5 apparent diameter; it became largest in a few seconds, then it grew thinner and appeared like a line. In 45 minutes, its brilliance diminished progressively, and it disappeared at the western horizon. "From astronomical observations by some amateur astronomers were calculated the following data: The object's altitude was between 600 and 650 kilometers above the earth's surface; at its biggest dimension, the object was 95 kilometers wide; it was over the Mediterranean Sea, in a place between Algiers and the Balearic Islands. "No astronomer was able to explain the phenomenon, and the university astronomical review Coelum denominated it 'un oggetto misterioso' (a mysterious object)."

... drowned landscapes. A stone tool encrusted with barnacles and bryozoa were recovered from a drowned delta flood plain now 53 m below mean sea level. This is the first tangible evidence that the subaerial broad banks of the western North American Continental Shelf may have been occupied by humans in earliest Holocene and possibly late glacial time. (Fedje, Daryl W., and Josenhans, Heiner; "Drowned Forests and Archaeology of the Continental Shelf of British Columbia, Canada," Geology, 28:99, 2000.) Comment. A map in the referenced report reveals that 12,000 years ago broad stretches of land several hundred kilometers wide bordered Canada, Alaska, and Russia. Not only could this exposed land have encouraged entry into the New World (as long-theorized), but the universal 500-foot drop in sea level provides ample opportunity to speculate about Atlantis and other drowned cities of earlier cultures now lost in time. One can imagine vast human-occupied plains abutting the steep, exposed edges of today's continents, then fringed withgreat waterfalls hundreds of feet high as the continents' rivers scoured out the great submarine canyons on modern bathymetric maps. There are few, if any, reliable accounts of this segment of human history, although speculation is rife about an Osirian Age, ancient sea kings, and the like. Finally, one must ask what caused the rapid rise in sea level shown on the graph? Were melting ice sheets sufficient? From Science Frontiers #139, Jan-Feb 2002 . 2001 William R.

... the New World until 12,000 years ago? Nevertheless, there they are: (1 ) rude human tools; and (2 ) a possible human palm print. Mainstream archeologists are stonewalling again; there must be some mistake! (Appenzeller, Tim; " A High Five from the First New World Settlers?" Science, 255:920, 1992.) Scene: Inside Amerind cells. DNA analyses of the mitochondria present in the cells of North American Indian populations indicate that the Eskimo-Aleut and Nadene populations arrived about 7,500 years ago. The more geographically widespread Amerind population, however, seems to be descended from two separate influxes; the first about 30,000 years ago, the second about 10,000 years ago. D. Wallace, from Emory University, surmises that the sharply defined rise of the Clovis culture, conventionally dated from 12,000 years ago, may have resulted from the second Amerind immigration. (Lewin, Roger; "Mitochondria Tell the Tale of Migrations to America," New Scientist, p. 16, February 22, 1992.) Comment. The 30,000-year date, however, is consistent with MacNeish's discoveries at the Orogrande Cave. Hang in there archeology anomalists, the 12,000year paradigm is melting in the warm spring sun!
