Not so, says Mark Cohen, of SUNY Plattsburgh. The switch from hunting and gathering to sedentary agriculture, it seems, occurred rather suddenly and was attended by a sharp drop in life expectancy. Ancient human bones reveal much more disease, fewer older people, and more violent deaths for centuries following the adoption of agriculture. Why did humanity give up the surprising degrees of security, freedom, and leisure intrinsic in hunting and gathering? Cohen claims that population pressure was the cause. Unable to stem the human population explosion, ancient humans were forced to adopt a life of toil, disease, and stress. (Lewin, Roger; "Disease Clue to Dawn of Agriculture," Science, 211:41, 1981.)

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.

The prehistoric ridged fields, canals, aqueducts, and other agricultural engineering feats found in South and Central America, and even our own Southwest, continue to amaze us. Almost totally forgotten, however, are the equally impressive "garden beds" of southern Michigan. Happily, the INFO Journal has just reprinted B. Hubbard's 1878 paper describing these works that stretched for miles along the Grand and St. Joseph Rivers. Of course, modern activities have obliterated them completely; and even in Hubbard's day they were mostly gone. First, Hubbard's general description of the "garden beds": "The so-called 'Garden Beds' were found in the valleys of the St. Joseph and Grand Rivers, where they occupied the most fertile of the prairie land and burr-oak plains, principally in the counties of St. Joseph, Cass and Kalamazoo. "They consisted of raised patches of ground, separated by sunken paths, and were generally arranged in plats or blocks of parallel beds. These varied in dimensions, being from five to sixteen feet in width, in length from twelve to more than one hundred feet, and in height from six to eighteen inches. "The tough sod of the ...

"For example, several areas that contain crosscrossing lines and figures similar to those of Nazca have recently been studied on the central coast [of Peru] between the FortalezaPativilca and Rimac valleys. Additional lines have been reported for Viru Valley, on the north coast, and for the Zana Valley, over 1,000 km to the north of Nazca. Interestingly, most coastal ground drawings that can be dated tentatively, either by associated ceramic remains and sites or by their similarity to diagnostic pottery motifs, fall in the earlier part of the Early Intermediate period (ca. 350 B.C . to A.D . 650) - i.e ., to a time following the establishment of irrigation agriculture as the primary subsistence focus, but prior to the rise of state societies. .. .. . "As is well known, several studies have been conducted that involved mapping and computer analysis of the Nazca lines to examine the hypothesis that they were related to astronomical phenomena. This theory is now discounted, at least as it applies to the great majority of the lines which do not appear to have been oriented toward the sky. More recent studies dealing with the lines have provided convincing arguments. primarily through comparison with lines currently in use on the Bolivian altiplano, that they were constructed as part of elaborate ritual ceremonies related to agricultural fertility."

Scientists have long known from laboratory experiments that various colors of light can affect stem size, root structure and other aspects of plant growth. But they have remained largely in the dark about the potential practical benefits of the phenomenon. "Using colored mulch to bathe plants in reflected light of certain hues, the South Carolina group (Clemson University) has begun to explore what colors plants prefer in agricultural growing conditions. Last year, for example, the group found that tomatoes grown with red mulch -- made with plastic sheets painted red -- had 20% higher yields than those with black mulch.

The Jomon culture extended over much of Japan in the period from 10,000 BC to 300 BC. Although the Jomon people are usually considered to have been hunter-gatherers, the Aomori site is demonstrating that they were much more sophisticated. They dabbled in agriculture (chestnuts, millet), traded for jade with southern Japan (400 miles away), and obtained obsidian from Hokkaido to the north across the Tsugaru Strait. The most startling find at Aomori was a group of six enormous holes in the ground containing the remains of massive wooden pillars 1 yard in diameter. Apparently, some huge structure once existed at this site. The Jomon, it now appears, were more advanced socially and technologically then previously believed. The finds at Aomori have been stunning to not only the archeologists but also the Japanese people in general, for the latter take great pride in their Jomon heritage. Complicating this picture is the fact that analysis of Jomon skeletons suggest that the Jomon did not closely resemble most modern Japanese. "Instead, they had features that made them look more like Caucasians and they seem to have resembled the Ainu, an ethnic group that still lives in tiny numbers in northern Japan. In the museum here in Aomori, Japanese tourists wandered by exhibits about the ...

Dug in the savannas and flood plains around Lake Okeechobee, the man-made circles include gaps where drainage canals extend outwards. Forty of these circular earthworks have been located by R.S . Carr. Some are as old as 450 BC; others as recent as the 16th. century. Mounds and large plazas are also part of this impressive example of Precolumbian engineering. Carr supposes that the circular canals were fish traps, but no fish bones or other supporting evidence for this theory have appeared. Another thought is that the earthworks drained agricultural land, but no maize pollen has been found. Could they have been ceremonial sites. No one really knows.

... A long article in Scientific American introduces us to the accomplishments of the Anasazi. We will concentrate here on their road system, but cannot let a few general statistics go by unnoticed. Of the nine Great Houses of the Anasazi in Chaco Canyon, in northwestern New Mexico, Pueblo Bonito is the best studied. It covers three acres and once rose to at least five stories, with some 650 rooms. Constructed of tightly fitting sandstone blocks, each Great House required tens of millions of cut sandstone slabs. For floors, the Anasazi carried logs from forests 80 kilometers away. The Chaco Canyon Great Houses required about 215,000 trees -- quite a problem in transportation. Strangely enough, the Great Houses seem to have been used only occasionally. In fact, Chaco Canyon was too poor agriculturally to support a large, permanent community. If this is so, what was the purpose of the Great Houses with their many kivas (large circular pits)? Obviously, they were for "ceremonial purposes" -- the standard explanation for enigmatic buildings and artifacts. The Anasazi also built a marvelous system of roads leading to Chaco Canyon. The accompanying map reveals hundreds of miles of roads converging from all directions on Chaco Canyon. For long distances, these roads measure a uniform 9 meters wide. They are flanked by linear mounds of earth and are impressively straight. The Great North Road, for example, runs true north for almost 50 kilometers. What was the purpose of these roads?. One theory is that they helped channel people to Chaco Canyon for the supposed ceremonies. ...

... became a vast fresh-water lake fed by Europe's rivers to the north. The Ice Age eventually waned, and the oceans and Mediterranean began to rise. About 7,000 years ago, the hydraulic pressure on the Bosporus silt plug became too great and it popped. Salty Mediterranean water poured into lowlands around the Black Sea. Scientists estimate that 50 cubic kilometers of water surged through the Bosporus each -- 200 Niagaras in one colossal waterfall. Falling some 150 meters, the thunder of falling water might have been heard 500 kilometers away! The Black Sea rose quickly, driving the shoreline and humans back a kilometer or two every day. The fleeing Neolithic farmers were forced up into the rich river valleys of Europe, carrying tales of the catastrophe as well as their culture and agricultural know-how into these areas. The Middle East was affected, too. The traumatic experiences of the survivors may have been the basis for the Sumerian and Biblical flood stories.

Deforest the jungle and the agricultural potential is about that of a your nearest Interstate highway. But the so-called "terras pretas" are curious exceptions. Spotted along Brazil's Aripuana River are small areas of deep, black earth that are from 7 to 17 feet deep. These are the "terras pretas" or "black earths." Scientists believe that these fabulously productive "islands" in the sea of otherwise poor soil were developed by native peoples about 10,000 years ago.

This level of virus density in natural water is about 10 million times that formerly estimated. Besides reducing your thirst, what are the implications of this discovery? First, it suggests that bacteria in natural waters are probably kept in check by viruses as well as protozoans. So far, this sounds good. Second, since viruses can ferry genetic material between organisms via transduction (i .e ., host DNA is carried to the next host). This means that genes for antibody resistance and increased bacterial virulence (as present in sewage) may be spread quickly and widely. Also, "engineered bacteria" proposed for use in agriculture, viz., the ice-minus bacterium created to protect strawberries, may die, but their new genes will soon be everywhere.
