Science Frontiers ONLINE No. 13: Winter 1981 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Remarkably Early Dates For Agriculture B.K . Maloney, of the British Museum, describes his pollen analysis of sediments that have accumulated in the Toba Highlands of North Sumatra, Indonesia. The base of a 9.7 -meter core from the Pea Sim-sim Swamp has yielded a radiocarbon date of 18,496 years. Pollen studies of the core indicate a brief decline of forest pollen about 17,800 BP along with increased sedimentation characteristic of cleared land. Taken by themselves, these data would probably be interpreted in terms of natural climate changes. But extremely early dates for human activity exist nearby: 14,000 BP for agriculture in Thailand and 11,000 BP for forest clearance on Taiwan. It is possible, therefore, that men were clearing land for planting in North Sumatra almost 18,000 years ago. (Maloney, B.K .; "Pollen Analytical Evidence for Early Forest Clearance in North Sumatra," Nature, 287:324, 1980.) Comment. Some archeologists hotly disoute the early dates mentioned above.

... in 1981. On the floor of the southeast Pacific, about 1400 kilometers west of Cape Horn, about 5 kilometers down, they found high concentrations of iridium in Upper Pliocene sediments about 2.3 million years old. Since the proposed projectile hit in very deep water, no crater was dug out. What did survive is called an "impact melt." This is debris rich in noble metals, such as iridium, and contains particles typical of a low-metal mesosiderite. Some 600 kilometers of the ocean floor received this debris. Kyte and his associates estimate the size of the impacting object at at least 0.5 kilometers in diameter. No biological extinctions are correlated with the 2.3 -million-year date, but there appears to have been a major deterioration of climate at about this time. There was a shift in the marine oxygen isotope records and, more obvious, the creation of the huge loess (sandy) deposits in China. What the impact may have done is to vaporize enough water into the atmosphere to increase the earth's albedo, reflecting sunlight back into space, lowering the average temperature, and thus triggering the Ice Ages. (Kyte, Frant T., et al; "New Evidence on the Size and Possible Effects of a Late Pliocene Oceanic Asteroid Impact," Science, 241:63, 1988.) Comment. Aficionados of the Ice Age problems will have to add this theory to the already long list of Ice Age hypotheses. From Science Frontiers #59, SEP-OCT 1988 . 1988-2000 William ...

... .C . Frisch, at the University of Chicago, has constructed a cosmic scenario that reminds us of F. Hoyle's science fiction tale, The Black Cloud . According to Frisch, until just a few thousand years ago, the solar system was cruising through interstellar space that was almost devoid of matter. Then, perhaps within historical times, 2,000-8 ,000 years ago, the solar system plunged into an interstellar gas cloud. This cloud is believed to be the remnant of the bubble of matter shot into space perhaps 250,000 years ago by a supernova in the Scorpius-Centaurus region. This tenuous cloud of gas feeds matter into the solar system, some of which interacts with the solar wind and, therefore, affects the geomagnetic field, too. Climate changes may have been caused by entry into this cloud, and very likely the flux of cosmic rays impinging on the earth would have been modulated. (Frisch, Priscella C.; "Morphology and Ionization of the Interstellar Cloud Surrounding the Solar System," Science, 265:1423, 1994. Also: Peterson, I.; "Finding a Place for the Sun in a Cloud," Science News, 146:148, 1994.) Comment. Note that the 2,000-8 ,000-year span brackets many key developments in human civilization. Also, see under ARCHEOLOGY in this issue. For a potentially serious effect this cloud may have on carbon dating. Getting back to Hoyle's "black cloud," we recall that his molecular cloud was ...

... the ice melts. The grains of rock settle into the ocean sediments which contain biological debris that can be carbon-dated. (Marine life beneath the ice sheets is surprisingly abundant and varied despite the near-freezing temperatures.) A somewhat politically incorrect observation appears in this article. However, the news that the Antarctic Peninsula's ice shelves may have come and gone at least once since the end of the last ice age, about 11,000 years ago, suggests that people may not be fully to blame for the disappearance now underway. Supporting foregoing evidence are studies of Antarctic lake sediments and ancient abandoned penguin rookeries. Everything points to a warmer, more humid Antarctica between 2,500 and 4,000 years ago. (Perkins, S.; "Antarctic Sediments Muddy Climate Debate," Science News, 160: 150, 2001.) Comment. The warmer Antarctic just portrayed might explain those old maps, such as that of Piri Re'is, that seem to depict a relatively ice-free Antartica. The more daring of us might postulate sea commerce between South America, southern Africa, and Australasia during those halcyon days! From Science Frontiers #138, NOV-DEC 2001 . 2001 William R.
