So, how did the marvelously crafted wings of birds, insects, and mammals evolve in infinitesimal steps? Biologists, including Darwin himself, have long puzzled over this. Stephen Jay Gould in a recent article explores a currently favored way of circumventing the negligible additional survival value of half a wing, or even 90% of a wing. This solution (? ) maintains that protowings were not "intended" for flight at all but were developed initially as aerodynamic stabilizers, thermoregulatory systems, sexual attractors or other functions requiring large areas. Gould describes the experiments of Kingsolver and Koehl in which protowings were modelled and tested for their thermoregulatory and flight values. Surprisingly, there was a sharp transition, as the size of the protowing increased, from good thermoregulation but poor flight capability to the reverse -- good flight capability and poor thermoregulation. In other words, a structure developed for one purpose, if enlarged, might be useful for something else! (Gould, Stephen Jay; "Not Necessarily a Wing," Natural History, 94:14, October 1985.

The essay goes far beyond the happy flamingo. It is about unusual adaptations in nature, as illustrated by three inverted or partially inverted creatures. The flamingo is a filter-feeder that strains food out of the water with its bill while its head is upside-down. The flaming's bill and tongue are (and must be ) radically different from those of other birds to succeed in this strange behavior. One type of jellyfish, rather than swimming around with its pulsating bell on top, plunks itself upside-down on the bottom and uses its bell as a suction cup to anchor itself. It then shoots poisonous darts attached to strings of mucous at passing targets and reels them in. Some African catfish graze on algae on the undersides of water plants. They swim upside down all the time and display a reversed color scheme, being black on the bottom and light on top. Gould employs these three examples to argue that changes in animal behavior must have preceded the many changes in form, function, color, etc. that make upside down living profitable. In other words, the proto-flamingos tried feeding with their heads upside down; and it didn't work too well. But "nature" responded with a series of random biological changes ...

The bottom 14 terraces are built from rather small stones; but the top four consist of slabs weighing up to 2 tons. Trees as old as 600 years poke up through the stones, attesting to a pre-European origin. Another much larger pyramid inhabits dense scrubland near Sydney. The claim that these admittedly crude structures are Egyptian is based upon the discovery of artifacts in the area with Egyptian and Phoenician characteristics; i.e ., a stone idol resembling a squatting ape, an onxy scarab beetle, and cave paintings with Egyptian symbols.

Wilson has outlined the diversity of terrestrial life in a recent issue of BioScience. The earth, it appears, is a veritable Gene sis Machine; and it is only one planet among a possible infinitude. So many terrestrial species have already been described that one could easily believe that biological collectors roaming the planet's wild places have just about completed their task. Some recent totals: 47,000 species of vertebrates, 440,000 plants, and 751,000 insects. But we may not even be close to grasping life's diversity on earth! We do well in counting the large mammals and birds, but most insects and microscopic forms of life have escaped description. To illustrate, in 1964, the British ecologist C.B . Williams, combining intensive local sampling and mathematical extrapolation, extimated the insect population as 3 million species. However, by 1985, this figure has been raised ten-fold to 30 million species. Why the huge jump? For the first time, entomologists had found a way to efficiently sample the canopies of tropical forests. This rich stratum between the sunlight and gloomy forest floor 100+ feet below had been largely neglected before. The slick tree trunks and the attacking swarms of wasps and stinging ants deterred the insect counters. What the collectors did was to fire projectiles with ropes over the high branches and then haul up canisters of a knockdown gas. ...

Several species of birds gather huge quantities of food when it is abundant and cache it for later use. On the surface this trait does not seem remarkable, but a look at the numbers of caches involved belies this superficial evaluation, especially to a species who forgot where he put the car keys a few hours ago. Take Clark's nutcracker as an ex-ample. A bird of the U.S . Southwest, Clark's nutcracker harvests conifer seeds when in season and buries them for future use during the rest of the year. One bird may bury as many as 33,000 seeds in thousands of caches, 4-5 seeds per cache. Its memory guides it back to those caches during the next year.

"His method was simple: classifications of animals and plants should be based on an assessment of their characters, and only advanced, or derived, characters (synapomorphies) should be used. For example, the character 'possession of feathers' is a synapomorphy shared by all birds that is found in no other organisms; it is used in classification to define Class Aves. All birds have a backbone too, but that is a primitive character for birds because it is seen in all other vertebrates. Primitive characters are of no use in defining a monophyletic group." Early on, cladism ignited many fireworks in the biological community. Today, cladism has become quite respectable. The cladists, however, are now fighting among themselves. One camp draws their "cladograms" (see illustration) using evolutionary theory as a guide. The other side believes that the cladograms should be drawn up first, based only upon actual characters and ignoring the theory of evolution -- let the species fall where they may. When evolutonary theory is omitted in the deliberations, radically different cladograms result. Mammals then seem more closely related to birds than reptiles, for example, as expressed in the illustration. A key connecting character here is mutual warmbloodedness. The shifting of ...

Metabolism based on fats allows some philodendrons to reach temperatures of 124 F. In terms of their rates of metabolism, they rival those of the humming birds. Further-more, philodendrons can regulate their chemical fires, whereas skunk cabbages, which burn only starch, consume all their stored energy like a rocket in one snow-melting crescendo. Why do plants generate heat? Apparently to attract pollinating insects. The hot skunk cabbage poking through the snow is the only food in sight for early spring insects, while the philodendrons may attract pollinating insects who like to bask or mate in warm places.

These parasites are merely bags of reproductive organs attached to a thorny probiscus, by which they attach themselves to the intestinal walls of vertebrates. Living in a sea of processed nutrients, the worms don't even have a digestive tract. Part of the life cycle of this parasite is spent in arthropods (insects, crustaceans). As with the lancet fluke, the thorny-headed worm's big challenge is getting the arthropod eaten by a vertebrate. In most instances, it alters the behavior of the arthropod in a way that makes it more conspicuous to the predators. For example, infested pill bugs do not hide from birds, as they normally do, and are snapped up. Infested crustaceans move towards the light where ducks consume them.

Now, in a recent issue of New Scientist, T. Hallam raises still more objections: Tropical plants, mammals, crocodiles, birds, and benthic invertebrates were little affected by whatever happened at the Cretaceous-Tertiary interface. Furthermore, many groups that were extinguished were already well into a decline. Some geologists insist that some of the supposedly synchronous extinctions were probably separated by several hundred thousand years; viz., plankton and dinosaurs. The vaunted iridium anomaly in deep-sea cores is spread through a considerable thickness of sediment. Even after allowing for the mixing of sediments, the iridium-rich layer is thousands of years thick. According to the asteroid scenario, the clay layer separating the Cretaceous from the Tertiary should represent the fallout from impact-raised dust, which would include asteroidal material and a mixed sample of earth rocks.

One must classify these impressive structures as works of art, even by human standards. For example, the bowers have geometrical organization and may be oriented to a specific compass direction, depending upon the species. Colorful berries, stones, and, when available, human artifacts are systematically arranged around the bower. Some bowerbirds even take a piece of bark in their bills and paint their bowers with colored berry juices. Each species has a certain style, but the bowers vary from individual to individual and with the age of the bird. Manifestly, these birds use tools for artistic purposes. Or do they? Is it all instinct? Some animal behaviorists believe the bower's purpose is to attract mates, but the males often chase females away, although mating does eventually occur within the bowers. A second explanation is that the bowers symbolize territorial rights. In this context, bowerbirds fre-quently raid and destroy neighboring bowers, stealing choice decorations -- all very human-like behavior.

The utility of these biologically manufactured compasses is obvious. Humans, too, seem to have a magnetic sense, although no one has yet dissected the human head to search for magnetite crystals. Rather, the 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.

Under low-angle illumination, the new specimen shows parallel impressions originating from the lower arm of the left "wing." These impressions are "interpreted" as imprints of feather shafts. Thus, the new fossil reinforces the mainstream position that Archaeopteryx really did have feathers and was a link between reptiles and birds. Evolutionists will rest easier now.

First, although the report on the new specimen states that the question of forgery does not arise here, even though the specimen's tail has been restored to the length deemed by the owner.

Payne authored an excellent review of brood parasitism in birds. Brood parasites lay their eggs in the nests of other species, which then incubate the eggs and raise the alien chicks. The parent parasites are thus free to forage, hang out, and parasitize more nests. Brood parasitism is such a successful and easy way of life that 136 species of cuckoos, 5 species of cowbirds, 20 finches, and South America's Blackheaded Duck have adopted it. Brood parasitism fascinates ornithologists because it involves war between the parasites and their hosts. Since host species may eject parasite eggs or fail to nurture parasite chicks, brood parasites have evolved mimicry as a powerful weapon in these battles. Mimicked are host eggs, host nestlings, and host vocalizations. But the most insidious weapons of all involve the outright murder of host chicks. To this end, parasite chicks have evolved some special weapons and behaviors. Some cuckoo chicks evict host eggs or chicks by squirming under them and positioning them in a specially configured hollow on their backs. Then, pushing upward and outward to the rim of the nest, they dump their cargo over the edge. Other brood parasites are more direct and bloodthirsty. "Nestling African honeyguides have bill hooks to stab and kill their nestmates and the brood parasitic American striped cuckoos have independently evolved hooks and pincers to kill." (Payne ...

The usual avian mode of retaliation involves defecation, especially on freshly washed and polished automobiles. On occasion, though, birds will use brute force. For example, keas (New Zealand parrots) consider it their duty to pry out the rubber gaskets around automobile windshields with their powerful bills. A cassowary can be even more forceful. Recently, a motorist near Cairns, Australia, was forced to stop by a sixfoot cassowary standing in the middle of the road. He edged the car forward slowly, but the huge bird stood its ground. Then, he blew his horn. Bad move! The cassowary objected by kicking the auto, pushing the radiator into the fan, which cut a hole in it. (Anonymous; "Feedback," New Scientist, p. 104, June 13, 1998.) Comment. The flightless cassowaries are armed with sharp toenails, with which they disembowel New Guinea natives who displease them.

Forming a short walkway behind the rear entrance were two sloping doors, which, when opened up, admitted entry to the basement stairway. Over a period of several days in mid-May of 1903, I noticed many small pebbles scattered about on these doors. I also heard from time to time the sound of small objects falling on the doors. Efforts to find the pebble-droppers were of no avail until one day when I happened to approach the rear of the building from the alley. My position some fifty feet from the building now permitted me to see several House Sparrows ( Passer domesticus ) bringing small stones to the edge of the roof and dropping them.

Perhaps they think a mole is tunneling after them, or maybe rain is beating down above. Whatever goes through their "minds," they emerge on the surface in response to vibrations and may be snapped up by several species that know their weakness. Human fishermen know the worms' weakness and "grunt" for them in several ways; say, by drawing a notched stick across the trunk of a small tree to generate vibrations. Wood turtles are said to "stomp" for worms. (SF#65) Kiwis and Kagus also stomp for their dinner. (Kagus are rather strange birds found in New Caledonia.) We have just learned that Woodcocks will beat their wings against the ground to coax earthworms within range.

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 ...
