Nematodes are about a millimeter long and very active, thrashing through the soil like fish through water. Their numbers are kept in check by a surprisingly sophisticated fungus which thrives on them. If nematodes are around (not otherwise), the fungus sets out two kinds of traps. The first is the sticky net made of threads sent out by the fungus. Any nematode that brushes against these sticky strands is held while the fungus rams special feeding pegs into it. The second kind of trap is even more marvelous. It is an array of rings, each consisting of three unique cells that are sensitive to touch. Attracted by alluring chemicals secreted by the fungus, the nematodes probe around the rings. In a tenth of a second after they are touched, the fungus rings contract around the interloping nematodes. Again the nematode is doomed as the terrible feeding pegs penetrate its body. Another chemical is then released by the fungus to keep other fungi away from its kill. (Simons, Paul; "The World of the Killer Fungi," New Scientist, 20, March 1, 1984.) Comment.

Science Frontiers ONLINE No. 116: Mar-Apr 1998 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Eco-Darwinism: Diffuse Individuals Epigenetic phenomena -- those phenomena beyond the pale of DNA -- are seen in "diffuse individuals" such as fungi, where it is difficult to separate individual units of life. To illustrate, some fungi may be 1,000 years old and extend for 35 acres (15 hectares) and yet possess a single, still unmodified genome. In his review of A. Rayner's new book Degrees of Freedom: Living in Dynamic Boundaries , T. Wakeford writes: "So, like the World Wide Web, a fungal network is decentralized. There is no central region capable of exerting control over the rest of the network. Rayner's own work suggests that the growth patterns of fungal filaments are forged as much by the environment that they encounter as by their genes. He believes that epigenetics, the process whereby opportunities in an organism's surroundings dictate which genes are expressed, is the norm in microorganisms. Genetic determinism is thus turned on its head." (Wakeford, Tom; "We Are the Fungus," New Scientist, p. 49, May 10, 1997.) Comment. Looking at the above situation from an information viewpoint, as one must these days, it seems that the environment can somehow "interpret" genes as the situation demands. In other words, genes are not "single-message" information carriers, but can be " ...

As travelers can attest, the warmer regions of our planet offer the spicier foods. In a way, this observation is a proof of microevolution. The "fitter" people (that is, "survivors") in hotter climes are those who have inherited a taste for hotter foods. Spices contain chemical compounds that inhibit or kill the bacteria and fungi that are more likely to poison foods where ambient temperatures are higher. Eaters of spicier foods are more likely to survive in these areas. This is not just a surmise. A study of 4578 recipes from 93 cookbooks from all over the world have been analyzed for spice content. Sure enough, the hotter the climate, the more recipes using spices and the hotter the spices used. In the language of science: "The proximate reason spices are used obviously is to enhance food palatability. But the ultimate reason is most likely that spices help cleanse foods of pathogens and thereby contribute to the health, longevity and reproductive success of people who find their flavors enjoyable."

During the past 12,500 years, a deep accumulation of exceptionally dense peat has formed. The basal peat is lignitic, but is several hundred times too young to be a true lignite. This peat does not decay as rapidly as it should, given its populations of bacteria, yeasts, and other fungi. The peat accumulates about ten times faster than in other peat-forming regions. The authors conclude that the peat-forming process is poorly understood. (Smith, R.I . Lewis, and Clymo, R.S .; "An Extraordinary Peat-Forming Community on the Falkland Islands," Nature, 309:617, 1984.) Comment.

It is the proposal that some of the structures that are found in the larger cells of animals, plants and fungi (eukaryotic cells) are the descendants of simpler bacteria-like organisms (prokaryotic cells) that had at some stage entered into an intracellular existence, or endosymbiosis. The idea is not a new one, but only in the light of modern experimental evidence has it become acceptable to many biologists. If the hypothesis is correct, then virtually all the major groups of familiar organisms originated 'suddenly' through endosymbiotic associations." Following this lead paragraph, with its paradigm-shaking final sentence, are three pages summarizing the biological evidence favoring evolution by endosymbiosis. (Kite, Geoffrey; "Evolution by Symbiosis; The Inside Story," New Scientist, p. 50, July 3, 1986.) Comment. We cannot possibly do justice to this exciting idea of evolution forced by the uniting of different organisms in the limited format of Science Frontiers. Instead, we encourage readers to purchase a new book by L. Margulis and D. Sagan (son of Carl Sagan and L. Margulis) entitled Micro Cosmos. In passing, we must also remark on the obvious relationship of endosymbiosis to F. Hoyle's ...

Sufficient heat and gas would have been trapped beneath the Martian surface to have generated living organisms, such and algae, bacteria, protozoa, and fungi. [What a leap of faith!] But life would have died out as the planet cooled and much of its atmosphere was dissipated. 'It is highly unlikely life could exist on Mars today,' [C .] McKay said. .. .. . "However some scientists have not dismissed the possibility that primitive life may still exist on Mars. 'The chances are remote but life may be located in slushy brines well below the surface, or even inside Martian rocks,' said Howard Klein, who headed the biological experiments on board Viking. Living microorganisms have been found just below the surface of rocks in Antarctica, Klein said." (Anonymous; Antarctica Hints at Why There May Be Fossils on Mars," New Scientist, p. 20, September 4, 1986.) Comment. It is curious that some of the meteorites picked up in Antarctica are thought to have originated on Mars and been blasted off by meteoric impacts. This observation leads to the speculation that terrestrial life might have been seeded from Mars -- meteoric panspermia! Are we all Martians? If you ...

... of life-synthesis. That the earth's crust and deep soil are conducive to life is apparent in recent work done sponsored by DuPont and the Department of Energy. This effort has found that life is abundant at least 850 feet below the surface -- a realm hardly suspected to harbor life. "' There is life down there, and it is very diverse,' says Carl Fliermans of Dupont's Savannah River Laboratory in Aiken, S.C . The numbers are high enough to affect the chemistry of the environment: Some of the samples contained as many as 10 million organisms per gram of soil. But even more surprising than the high concentrations is the diversity of the microorganisms, according to David Balkwill of Florida State University in Tallahassee. Many varieties of bacteria and fungi have been seen, and there have been indications of amoeba. And the diversity -- which doesn't appear to decrease with depth -- may force a reappraisal of the environment that lies between soil and bedrock."

... pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Microbes Threaten Radiocarbon Dating In the 1980s, skeptics had a lot of fun debunking the Shroud of Turin, the supposed burial cloth wrapped around Christ. Their glee was unbounded when radiocarbon dating "proved" that the shroud could not be older than 700 years. The skeptics may have been too quick to celebrate, because the samples that were sent to the radiocarbon lab may not have been wholly cloth. The reality of our biosphere is that virtually everything is permeated with microbes and their products. S.J . Mattingly and L.A . Garza-Valdes, of the University of Texas at San Antonio, have been studying "biogenic varnishes" for years. These plastic-like coatings are produced by bacteria and fungi. Sure enough, microscopic examination of a few linen fibers from the Shroud of Turin show that they, too, are coated with such varnishes. These biogenic varnishes may introduce carbon that has been recently fixed from the atmosphere and thus make the sample's age appear younger than it really is. (Travis, John; "Microbes Muddle Shroud of Turin's Age," Science News, 147:346, 1995.) Comment. More than the Shroud is at stake here. Bacteria contaminate just about everything, including wood and bone from archeological sites. Bacteria may, therefore, "rejuvenate" samples sent in for radiocarbon dating. The importance of this phenomenon is still unclear. Cross reference. Radiocarbon-dated samples may also appear erroneously "aged" by the uptake ...

... Based Life Virtually all biology textbooks insist that all terrestrial life ultimately depends upon sunlight for its survival. The ecosystems clustered around the deep-sea vents and the bacteria found in deep aquifers demonstrate that the sun is not essential to life -- chemical energy does just fine. In fact, the domain of chemosynthetic life has now been extended to a Romanian cave that has apparently been almost completely sealed off from surface influences for 5.5 million years. Air does leak in through tiny cracks, and water partially fills the cave. What is most remarkable in this sunless, sealed ecosystem is its biodiversity: 48 animal species, including 33 brand-new species. The roster includes isopods, a millipede, a centipede, a water scorpion, and a leech. Of course, bacteria and fungi thrive there, too. In contrast to unsealed caves, where insects, bats, and other sources of food filter in from the surface, life in the Romanian cave seems to derive entirely from hydrogen sulfide present in the cave's rocks. This compound is consumed by microorganisms, which are then grazed by cave occupants higher up the food chain. A NASA scientist has called Movile cave a "Mars analog site." And indeed it might be, for Mars has plenty of rocks and subsurface water. (Skinrud, E.; "Romanian Cave Contains Novel Ecosystem," Science News, 149: 405, 1996) Comments. Fluid-filled cracks and pores extend miles down below the earth's surface. It would be surprising if novel ecosystems do not exist there ...

... outer space," as implied in third item! Bacteria and placer gold. "Lacelike networks of micrometresize filiform gold associated with Alaskan placer gold particles are interpreted as low-temperature pseudomorphs of a Pedomicrobium -like budding bacterium. Submicron reproductive structures (hyphae) and other morphological features similar to those of Pedomicrobium occur as three-dimensional facsimiles in highpurity gold in and on placer gold particles from Lillian Creek, Alaska." In short, bacteria help create placer gold deposits. The author believes that bacterioform gold is widespread. (Watterson, John R.; "Preliminary Evidence for the Involvement of Budding Bacteria in the Origin of Alaskan Placer Gold," Geology , 20:315, 1992.) Microorganisms and iron deposits. At least 500 million years ago, filamentous bacteria and/or fungi were already playing vital roles in the deposition of iron from hydrothermal fluids. Abundant microbial filaments indicative of biological activity are found in the Cambrian ironstones in Australia's Thalanga deposit. (Duhig, Nathan C., et al; "Microbial Involvement in the Formation of Cambrian Sea-Floor Silica-Iron Oxide Deposits," Geology , 20:511, 1992.) Deeper implications. The formation of placer gold and ironstone are only part of the repertoire of deep-living microorganisms. A five-year survey of microbial life conducted by the U.S .
