Some 40,000 caves are known in the United States alone. There are thought to be ten times that number that have no surface openings and therefore escape spelunking census takers.

The truth is that a map of the human genome will not tell us everything.

It now seems that the human ear-brain combination can also discern the shapes and dimensions of thin, vibrating plates by the sound they make. In one type of experiment, conducted by A.J . Kunkler-Peck (Brandeis University) and M.T . Turvey (University of Connecticut), subjects gave surprisingly accurate estimates of the heights and widths of ... that larger plates. How-ever, the ability to assign accurate dimensions without some training is surprising. The same can be said for the identification of shapes. Who, for ex-ample, has been exposed to vibrating, triangular-shaped plates in ordinary life? Could we be dealing here with another innate talent that, like perfect pitch, seems to have no adaptive value in the evolution of humans? From Science Frontiers #129, MAY-JUNE 2000 . 2000 William R.

Science Frontiers ONLINE No. 137: SEP-OCT 2001 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Mysterious Losses And Acquisitions of Color Vision The eyes of most mammals incorporate two types of color-sensitive cones; one for seeing blue light, the other for green light. Such mammals have bichromatic vision and discern colors rather well. Humans and the other primates are blessed with trichromatic vision, for their eyes have cones that register red light. Does this indicate evolution superiority? Hardly, birds possess five types of color-sensitive cones that sense two additional parts of the spectrum. How and why these enhancements in color vision occurred are not well-understood. Nor do we know why they were restricted to mammals and birds; although it ... easy to fabricate several survival-of-the-fittest scenarios. The "how" part of the mystery is particularly hard to grasp in neo-Darwinian terms because the complex pigments that confer spectral sensitivity upon the cones represent remarkable, complex chemical syntheses. Also mysterious is the apparent loss of color vision in 14 species of toothed whales and seals. (Only 14 species were examined; there may be more.) These particular whales and seals lack the blue-sensitive cones, even though they are descended from mammals with bichromatic vision (hippos and otters, respectively). This deficiency is doubly perplexing: Sensitivity to blue light is highly desirable in the ocean environment because it is blue light that penetrates seawater well. The loss occurred in two mammalian lineages not particularly closely related on the ...

... about everyone will concede that when sodium and chlorine atoms arrange themselves to build salt crystals that they are simply obeying the well-known laws of physics. In other words, salt crystals are "natural." "Intelligent design" need not be invoked in explaining their existence. This is OK for salt crystals but can we say the same for biological forms such as proteins and, ultimately, human beings? Are these more complex biological forms also natural; that is, reducible to and explainable by the laws of physics? Human beings certainly seem irreducible; and some proteins are so large and complex that one is unsure that physics is up to the task of explaining these tangled structures consisting many hundreds of atoms. Some of these doubts have been relieved by recent advances in protein chemistry. ... gasp!) mammals. This is, of course, reductionism in the extreme. But the successes with protein folding have led two New Zealand biochemists to speculate as follows: If it does turn out that a substantial amount of higher biological form is natural, then the implications will be radical and far-reaching. It will mean that physical laws must have had a far greater role in the evolution of biological form than is generally assumed. And it will mean a return to the pre-Darwinian conception that underlying all the diversity of life is a finite set of natural forms that will recur over and over again anywhere in the cosmos where there is carbon-based life.

Photoreceptors are sensitive to light but do not produce images. They are found in many groups of animals. Even humans possess photoreceptors besides their eyes; specifically, in the pineal gland and, perhaps, the knees. (SF#116, SF#117) The pineal gland (our "third eye") may have registered photons at some stage in our evolution, but it is now useless or adapted to other purposes. The arthropods, however, still find photoreceptors useful. Crayfish have them on their abdomens, where they initiate an escape response when illuminated. Additionally, ... blind shrimp that collect around the glowing deep-sea vents have photoreceptors perched on their backs, presumably to guide them to their prey located around the luminous vents. Recently, the Japanese yellow swallowtail butterflies were discovered to sport photoreceptors on their genitalia. These I are used during mating to confirm the position of the female's ovipositor.(Arikawa, Kentaro; "Hindsight of Butterflies," BioScience, 51:219, 2001.) Barn-Owl auditory neurons multiple signals. Barn Owls can locate rustling mice in the dark with high precision. They discern their prey by sound rather than light. To achieve the high accuracy needed to home in on small rodents in the black of night, their ears are slightly offset so that they can draw a bead by using microsecond time- ...

... s hard drive looks like? Maybe memory is hologrammic. And when a memory is pulled off the mind's hard drive, how is the information conveyed to the central processing unit, assuming there is one? Is it all done through nervous impulses, or are proteins transferred bodily. This computer analogy is probably incorrect. Nature is probably cleverer than PC makers! The demonstrable fact is that human memory is malleable, and this seems anomalous in terms of the evolution paradigm.

When one relects upon this matter, a rational, cause-and-effect chain is not far out on the lunatic fringe. After all, a pregnant woman's body responds to varying temperatures, changing amounts of sunlight, seasonal foods, and varying physical activity during the year. Such effects can be felt in utero, too. Many of the multitudinous studies looking into the season-of-birth correlations are very specialized and employ small samples. For example, English professional soccer ... to have been born September through November. Mental traits are also influenced by season-ofbirth. More medical students are born April through June than can be explained by chance. Best of all (for us) is the following correlation: Perhaps the most unusual seasonal effect is found amongst scientists who support revolutionary theories. It seems that academics who were quick to support controversial theories such as relativity and evolution tended to he born between October and April.
