(From: Eastman, Joseph T,; Antarctic Fish Biology , San Diego, 1993.) In the frigid waters ringing the continent of Antarctica live approximately 275 species of fishes, 95 of which are assigned to the suborder Notothenioidei. This particular group of fishes is renowned for its unusual adaptations, as outlined below by D. Policansky: "Some of them have glycoprotein antifreezes in their blood, some have no hemoglobin, some have so small a temperature tolerance that they die at temperatures above 4 C, some are neutrally buoyant despite lacking swim bladders, and some live as deep as 2950 meters. The suborder has no known fossils, largely because no bony feature -- indeed, no single character of any sort -- can be used to define it. How did these animals arrive there, what are their ancestors, how do they make a living in such an environment, and how can they support commercial harvests?" (Policansky, David; "Southernmost Fauna," Science, 264:1002, 1994.) Comment. Those species lacking hemoglobin in their blood are doubly perplexing: (1 ) Zoologists still do not know how sufficient oxygen is transported in these fishes, for what substitutes for normal blood seems inadequate; (2 ) How could they have evolved from hemoglobin-carrying fishes? and (3 ) Why switch from hemoglobin at ...

... Science Frontiers ONLINE No. 17: Fall 1981 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Why conserve junk?A. Jeffries, working at Leicester University with globin genes from man and related primates, has been studying how these genes direct the blood cells to make the alpha and beta chains of hemoglobin. Jeffries' analyses seem to indicate that the genes now coding for these hemoglobin chains are almost identical to those existing in human ancestors some 500 million years ago. Two curious facts have cropped up, however. First, about 200 million years ago, these genes were modified very slightly and relocated to entirely different chromosomes. Second, 95% of the DNA associated with these genes is "junk" -- with no known use. Why did nature conserve junk for 500 million years? Are vital genes in the habit of jumping from one chromosome to another? (Yanchinski, Stephanie; "DNA: Ignorant, Selfish and Junk," New Scientist, 91:154, 1981.)

... well-observed tendency of the universe to run down; that is, become more disorderly. In some situations, though, the increase in disorder (entropy) in one part of the universe can create order elsewhere. For example, if you add tiny plastic spheres of two sizes to salty water, you will not get a uniform mixture. Instead the larger spheres will pack together into tightly ordered crystaline shapes (representing more order) while the smaller spheres become more disordered. It is like watching cream unstir itself from coffee. It smacks of magic, but it is all within the laws of thermodynamics. This strange "force" exerted by entropy may explain some puzzling biological phenomena, such as the expulsion of nuclei from mammalian red blood cells before they enter the bloodstream as sacks of hemoglobin. The idea being that the increasing entropy of the proliferating hemoglobin molecules (analogous to the smaller spheres) is maximized when the nuclei (large spheres) are squeezed out of the cells altogether. (Kestenbaum, David; "Gentle Force of Entropy Bridges Disciplines," Science, 279:1849, 1998.) Comments. The red-blood-cell example presented in the article is on shaky ground, because while mammalian red blood cells do lack nuclei those of birds and reptiles retain theirs. (See BMC6 in Mammals II .) In the above context, the origin of life (more order) anywhere in the universe can be thought to be due to the "gentle force" of entropy; that is, the result of increasing disorder elsewhere. See? It' ...

... Science Frontiers ONLINE No. 3: April 1978 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Extraterrestrial Influences On Chemical And Biological Systems Conventional science shows little interest in the subject indicated by the title, except for some work that is done on circadian rhythms. However, readers of the journals Cycles and the Journal of Interdisciplinary Cycle Research are treated regularly to a wide variety of purported correlations of biological systems with solar and other extraterres-trial influences. The present paper suggests that extraterrestrial forces influence the earth's weather which, in turn controls physiological processes. The physiological processes studied include blood precipitation rate and blood hemoglobin values. Also mentioned are Piccardi's precipitation-rate experiments that seem to show a highly variable behavior of simple chemical systems that bear no obvious relationship to weather conditions. Tromp concludes from these data that unknown forces, probably extraterrestrial in nature, act upon the earth and its inhabitants.
