Many Polynesian navigators did indeed set out from sunswept lagoons into the superficially featureless Pacific. How did these peoples, a thousand years ago, sail reliably from one speck of land to another, thousands of miles distant? The archeology of Oceania confirms that the Polynesians made such voyages centuries before they learned about compasses and navigation satellites. But were these voyages anomalous; that is, did the Pacific peoples possess devices or talents unrecognized today by mainstream science? For the most part, the answer seems to be NO. While the navigational abilities of the Polynesian seafarers seemed supernatural to early European explorers, it has been convincingly demonstrated -- through modern voyages -- that the senses of sight, hearing, smell, touch, and time-passage are and were sufficient for most interisland voyages. The early Pacific navigators were adept at observing the waves, stars, birds, clouds, winds, and several other natural phenomena that carry subtle directional cues. There are, however, modern instances in which Pacific navigators bereft of the usual sensory cues seem to employ an anomalous "sense." B. Finney, in his study of the possibility of human magnetoreception, tells how one native Hawaiian navigator, though wellschooled in traditional Polynesian navigational techniques, conquered the dread doldrums on a 3,000mile voyage from Hawaii to Tahiti in a way ...

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 Monarch Compasses Field experiments down the years suggest that migrating birds use a variety of strategies to chart their courses with high precision. The geomagnetic field, the sun, the stars, prominent landmarks, and even odors help guide them across the continents and open seas. But birds are considered highly evolved animals so their sophisticated navigational techniques are not especially surprising. Monarch butterflies, however, are mere insects, with tiny brains (navigation-data processors) and not much in the way of the environment sensors and internal clocks required for long-distance migration. Yet, some of these colorful insects manage to flutter up to 4,000 kilometers from the eastern U.S . and Canada to their wintering grounds in Mexico. How do they do this? S.M . Perez et al have now shown that monarch butterflies are equipped with a sun compass; that is, they chart their courses by noting the sun's changing azimuth. This feat requires not only the measurement of solar azimuth but also reference to an internal clock. Humans cannot do this without artificial instruments. Furthermore, even on cloudy days, migrating monarchs fly in the proper direction (generally south-southwest). Apparently, they also have evolved a backup navigation system, perhaps a geomagnetic compass. (Perez, Sandra M., et al' "A Sun Compass in Monarch Butterflies," Nature, 387:29, 1997.) Comment ...

The problem has been exacerbated by recent experiments with German and Austrian blackcaps. These two common European warbler species take different routes to Africa in the winter. The Ger-man blackcaps fly southwest and the Austrian southeast--routes 50 apart. A. Helbig has crossed the German and Austrian blackcaps to see what route(s ) their hybrid offspring would take. Curiously, they favored a route intermediate between those of their parents. The hybrids' route -- bisecting those of the parents' -- would take the hybrids right into the Alps, where survival would be unlikely.

Rather, it grows in conjunction with a fungus that obtains nutrients from surrounding roots. The fungal threads penetrate both roots and orchids. The orchids make ends meet by systematically killing and digesting the nutrient-laden fungal threads. When the orchid flowers, it pushes toward the surface just enough to open some tiny cracks in the earth. In these cracks, still below the surface, appear the tiny burgundy red flowers. These flowers are pollinated by minute flies, but just how the orchid's seeds are dispersed is still a mystery. (Cooke, John; "Hidden Assets," Natural History, 93:75, October 1984.) Bats navigate by somehow constructing an image of the external world from the echoes of their squeaks. Since bats have but two ears, one wonders how they can develop a three-dimensional image from a two-dimensional sensor; ie., two ears give right-and-left information only. The moustache bat makes up for this deficiency by generating echo-locating pulses at three distinct harmonics: 30, 60, and 90 kilohertz. Its external ears are so shaped that each of these three frequencies has a different acoustic axis, giving the bat in effect three separate sets of ears pointing in three different directions. Inside the bat's head, in the inferior colliculus of the brain, are three sepa rate sets of neurons sensitive to the three different frequencies. No one knows how ...

At the rate measured by the satellite, the Earth's field will hit zero in about 1200 years. Of course, NASA's scientists warn that the observed decrease may only be a temporary fluctuation. The geological record seems to register a long history of magnetic field reversals, with great biological changes coinciding with the field flips.

But one mystery has been replaced by several. It seems that there were three different species of dolphins, and they were found at the closed ends of underwater passages that were just a bit larger than the living animals themselves. Why did three different species go into the caves at all? Why did they go all the way to the ends of the closed passages, given their excellent echo-location systems? Pertinent here is the discovery of skeletons and recent carcasses of green turtles in similar situations in underwater caves in Indonesia. Turtles lack the dolphins' echo-location equipment, but they are still excellent navigators. (Molnar, R.E .; personal communication, July 2, 1991. Molnar is a scientist at the Queensland Museum.)

Klimley et al next implanted some sharks with transmitters and followed them at night. This was their feeding time, they swam 10-15 miles to deep waters where they gorged on squid. At daybreak, they were back drifting around Espiritu Santo. Apparently, the mountain was just a place to rest. But how did the hammerheads find their way back so unerringly? Furthermore, by tracking the tagged fish, the researchers found the sharks often precisely followed the same paths in what seemed a featureless ocean. How did they do it? It was quickly ruled out that they were following specific ocean currents or the bottom topography. The hammerheads seemed to possess some sort of unrecognized navigation sense. Suspecting they might be sensing the geomagnetic field, Klimley began towing a magne tometer behind the boat. Sure enough, the hammerheads were following paths coincident with lines of high magnetic gradient. And Espiritu Santo itself turned out to be a sort of magnetic beacon from which radiated these magnetic "paths" that the hammerheads followed so exactly. Now the question became: How do hammerheads -- and perhaps other animals -- sense such exceedingly small changes in the geomagnetic field? Some birds and mammals do have small particles of magnetite in their bodies, but no one knows how they might be incorporated into a sensory organ.

Now, we add two more remarkable capabilities to their dossier. Precision navigation. The oily, flexible shells of leatherbacks have made it difficult for researchers to attach radio transmitters to the animals. Their very deep dives (over 1,000 meters) are also inimical to human instrumentation. But S.J . Morreale's group at Cornell have succeeded in attaching pressure-resistant transmitters to the shells on short tethers. This team was able to track female leatherbacks as they left their nesting beach in Costa Rica and headed southward, past the Galapagos, out into the open South Pacific. Surprisingly, all the leatherbacks plied a very narrow corridor each year of the experiment (1992-1995). In fact, the paths were almost for at least 2,700 kilometers southwest of the Galapagos. Highprecision navigation equipment is required here. Among the leatherbacks' "instruments" are probably sensors that detect the angle of the geomagnetic field, the length of daylight, and the identities of the oceanic currents encountered. There are probably other sensors and, of course, a brain to process all the signals; but virtually nothing is known about them.

Although experts prefer to avoid simplistic definitions of intelligence, it seems clear that all intelligence involves the rational manipulation of symbolic information. This is exactly what happens when army ants pass information from individual to individual through the 'writing' and 'reading' of symbols, often in the form of chemical messengers or trail pheromones, which act as stimuli for changing behavior patterns." During its 20-day stationary phase, an army ant colony scatters about 14 foraging raids directed 123 apart. The heavy line indicates the colony's path during the nomadic phase. In the body of his article, Franks describes two remarkable capabilities of an army ant colony: time-keeping and navigation. The outward manisfestation of time-keeping is in the precise timing of the colony's nomadic phase of 15 days (during which larvae are growing) and the 20-day stationary phase (during which pupae develop). The queen's egg-laying also conforms with this schedule. Raids into the rain forest occur in both phases. Perhaps more remarkable is the systematic orientation of the raids in the stationary phase. These raids are separated by an average 123 , as diagrammed. This scattering allows time for new prey to enter the previously raided areas. But how does the colony determine direction in the dense rain forest? Probably from polarized sinlight, thinks Franks.

They communicate with one another and navigate through their world of grass and vegetation by laying down trails of scent-laden urine. The world of kestrels -- eaters of voles -- is one of sight. Now, voles are hard to see in the grass far below a hunting kestrel, but evolution has come to the aid of the kestrels by giving them the capability to see in the ultra-violet portion of the spectrum.

Kirschvink, of the California Institute of Technology, has plotted the hundreds of beachings of whales and dolphins along the U.S . east coast. He finds that these cetaceans tend to run aground at spots where the earth's magnetic field is diminished by the local magnetic fields of rocks. These coastal magnetic lows are at the ends of long, continuous channels of magnetic minima that run for great distances along the ocean floors. Kirschvink believes that the stranded whales and dolphins were using these magnetic troughs for navigation and failed to see the stop sign at the beaches and ran aground. The mag-netic troughs in this view are superhighways for animals equipped with a magnetic sense. If Kirschvink's theory is correct, the magnetic sensors of the whales and dolphins are extremely sensitive, because the deepest magnetic troughs are only about 4% weaker than the background magnetic field. Magnetite crystals have been found in birds, fish, and insects, where they are thought to contribute to a magnetic sense of some sort. So far, no magnetite has shown up in whales and dolphins.

In the context of one electrosensory behaviour, the jamming avoidance response (JAR), the fish Eigenmannia determines whether a neighbour's electric organ discharge (EOD), which is jamming its own signal, is higher or lower in frequency than its own. The fish then decreases or increases its frequency, respectively. To determine the sign of the frequency difference, the fish must detect the modulations in the amplitude and in the differential timing, or temporal disparity, of signals received by different regions of its body surface.

Many have so surmised; and there exists anecdotal evidence for it. A Swedish ecologist, T. Almberstam, decided to attempt scientific observations. At Norberg, in central Sweden, a huge deposit of magnetite creates a powerful magnetic anomaly. The deposit is 12 kilometers long by several wide. At low altitudes, the total magnetic intensity of the earth's field is 60% higher than normal. What happens when migrating birds fly into this magnetic bump? "Although Almerstam found that many migrating birds showed no signs of avoiding the Norberg anomaly, and often managed to keep on the right course as they passed through it, there were definite indications that the birds' orientation might be affected under special circumstances. Some migrants flying at low altitudes, where the magnetic intensity was greatest and the inclination and declination distorted greatly, became disoriented briefly. They nervously landed and then circled around before taking off again. Other birds changed their altitude abruptly, dropping 100 metres in two minutes and breaking up their flock formations." Certainly something is happening, but no one knows what. (Anonmous; "Magnetic Anomaly Upsets Migrating Birds," New Scientist, p. 32, November 5, 1987.)

... and Southeast Asia (right) The Mayan codices were made from bark paper as opposed to ordinary paper. To make bark paper, one first takes the inner layer of bark, or bast, from a tree. This material is then thinned, widened, and made flexible by soaking it in water and beating it. The final product retains much of the bark's structure with its interconnecting fibers. Ordinary paper today is also made of wood fibers, but the original fiber interconnections are destroyed in the pulping process. The manufacture of bark paper requires characteristic grooved beaters, specimens of which have been found in both Mesoamerica and Southeast Asia. Were bark paper and the tools required to make it invented independently on both sides of the Pacific, or were they transported across the Pacific by early navigators? If the latter, the flow was probably from Asia to America because the paper-making tools first appeared in Southeast Asia 4-5000 years ago and in Mesoamerica only 2500 years ago. Even so, trans-Pacific voyages 2500 years ago are definitely not part of acceptable archeology. Anthropologist P. Tolstoy, swimming against the mainstream, has surveyed the manufacturing technology of both bark paper and ordinary paper on a worldwide basis. He identified some 300 variable features in the process, 140 uses of the final products, and 100 specific details of bark beaters. Tolstoy concluded: "All this points to the direct transfer of technology from Southeast Asia to Mesoamerica, apparently by a sea voyage that took place about 2500 years ago." Tolstoy rejects the tapa (bark cloth) of ...

... proof of a magnetic sense comes from direction-finding experiments by Robin R. Baker, in England. In a series of tests involving many subjects, blindfolded humans have been taken far afield and then asked, while still blindfolded, to point "home" and north. The results were surprising. Sense of direction was not lost despite long journeys. Furthermore, tests after removal of the blindfolds showed a marked deterioration of the directionfinding ability. The attachment of magnets and simulated magnets to the subjects proved that the magnets upset di-rection-finding capabilities. The controls with brass "magnets" retained their magnetic sense.

... clicks and other sounds sonar-fashion ahead of the swimming animal, which then listens for echoes from prey and other targets. But what if these bursts of sound could be made very powerful -- could they be employed to stun and disorient prey? Bits of evidence are accumulating to support the theory that some whales and porpoises actually have acoustic stun guns in their foreheads. First, there are visual observations of fish being hunted by whales and porpoises suddenly giving up flight, becoming passive, and almost asking to be snapped up by their pursuers. Second, the stomachs of whales often contain much faster and more mobile prey -- often without any teeth marks. Finally, bottlenose dolphins are known to have the capability of producing bursts of sound five orders of magnitude more intense than their usual navigating clicks. This is more than enough to kill small fish. (Norris, Kenneth S., and Mohl, Bertel; "Can Odontocetes Debilitate Prey with Sound?" American Naturalist, 122:85, 1983.) Comment. Here is another instance of the "problem of perfection." An existing organ of great complexity seems utterly useless of only fractionally developed. One would think that the complicated sound lenses, the muscular sound-generating tissues, and their containing structures would have to have developed in a single step in order to have any survival value.

... what happened on October 5 may never be known. On that day thousands of homing pigeons were released by their proud owners in widely separated locations expecting they would quickly race home to their lofts. Few made it. In three separate races in New York and Pennsylvania, a total of 4,000 birds were released on October 5. Only 400 returned home. 3,000 pigeons released in California on the same day are still missing. All over the planet, homing pigeons are not homing as well as they used to. Performance has been falling steadily over the past two decades. The favorite theory blames geomagnetic storms, but no such correlation has been shown. Microwaves are fingered next. Cell phones and satellite communications fill the atmosphere ever more densely with microwaves that may throw off the navigation equipment of homing pigeons, but this hasn't been demonstrated yet either.

Did the old navigators sail into these now-frigid waters and map this great southern continent? One way to answer such questions is by turning to old maps and, then, asking the geophysicists if most of the continent's ice cover could have disappeared fairly recently, as some ancient maps are purported to show. C.P . Hapgood, well known for his book Maps of the Ancient Sea Kings, believed that ancient mariners did indeed map Antarctica when those climes were warmer. More recently, J.G . Weihaupt came to similar conclusions by a different route, which included geophysical considerations. (See SF#36 and #38.) Now, D.C .Jolly has put the whole problem in perspective in an excellent review. Jolly has studied the data in depth, as indicated by his 51 sources. In his view, it boils down to the fact that the old maps, which people of all persuasions use, are often incomplete and ambiguous. One can read a lot into them. To claim an ice-free Antarctica, one has only to make a few assumptions. For example, one reduces the size of a map feature here and rotates another there. It seems that those old map-makers didn't get things quite right! Jolly is fair about the whole business and ...

Carter reminisces, he found in the Johns Hopkins library a book entitled: Deutsches Verein fur Wissenschaft zu Santiago Chile.

But so far, biologists do not have the slightest notion how such magnetite particles can be turned into a "magnetic sense," which sends the brain information on the direction of the geomagnetic field or, perhaps, draws a magnetic map of sorts. A completely different sort of magnetreceptor is now under investigation, one that humans may also unknowingly possess. It utilizes special photoreceptors that employ an electron-spin resonance process which is modulated by the geomagnetic field. Some of our very sensitive magnetometers use similar phenomena. The biological version of such a receptor would be connected to the brain, as the eye is, and send signals as to the direction of the earth's magnetic field. Sounds interesting, but is there any basis for thinking such a sophisticated gadget could have evolved? It seems that some experiments with newts by J.B . Phillips and S.C . Borland support the idea. The newts were first trained to orient themselves in a certain direction with respect to the geomagnetic field. "When tested under one of four artificial field alignments (magnetic north at geographic north, east, south or west), the newts kept their training directions constant relative to the magnetic rather than the geographic system of reference, but they selected ...

This is particularly puzzling because neutrinos are presumably generated in the solar core, whereas sunspots are supposed to be manifestations of solar-surface activity.
