... Science Frontiers ONLINE No. 69: May-Jun 1990 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Spontaneous order, evolution, and life In our thinking, one of the most remarkable articles ever to appear in Science bears the above title. Most re markable of all is the use of the word "spontaneous" without philosophical comment. The stimuli for the research described are such observations as: (1 ) life exists; (2 ) life evolves; (3 ) the fossil record displays stasis, extinctions, and great gaps between phyla and lesser classifications; and (4 ) disordered molecules move smoothly and surely into the order manifest in the living cell. The question asked in the article is whether science has missed something in its description of the origin and development of life. Just what makes molecules coalesce into cells and humans? The answer given is: spontaneous self-organization ! In other words, there is no guiding external force. Molecules do this spontaneously. There are even computer models being developed, based on a branch of mathematics called "dynamical systems," that describe how this all happens - spontaneously, of course. (Waldrop, M. Mitchell; "Spontaneous Order, Evolution, and Life," Science, 247:1543, 1990.) Comment. When water molecules spontaneously cluster together to form a snowflake, with all its symmetry and order, science explains the process in terms of the properties of water molecules. The same must be true when molecules merge to form life forms. But ...

... Is A Real Problem The reader should refer to the following item for the basic paleontological facts discussed by Williamson. The biological implications of the mollusc lineages drawn up by Willianson are rather profound. In the present item, Williamson complains that scientists and critics have focussed primarily upon his claim that his mollusc lineages support the punctuated evolution model (which they do) but avoid his main point: namely, that the lineages are static over very long periods of time. They do not change slowly, bit by morphological bit, into new species as an evolutionist would expect. Instead, they remain un-changed until they become extinct. This striking aspect of the fossil record is not predicted by neo-Darwinism -- and there is the rub! (Williamson, Peter G.; "Morphological Stasis and Developmental Constraint: Real Problems for Neo-Darwinism," Nature, 294:214, 1981.) Comment. In neo-Darwinism, evolution unfolds by small accumulated changes, the causes of which may be chemicals in the environment, nuclear radiation, and other "stresses." Neo-Darwinism goes hand-in-hand with geological Uniformitarianism, both of which are favored philosophically by scientists because slow change is more amenable to scientific explanation. The large sidewise steps of punctuated evolution are difficult to explain in terms of known "forces." In this context, the radical concepts of directed panspermia and the impact of viruses on evolution may be important! From Science Frontiers #19, JAN-FEB 1982 . 1982-2000 William R. Corliss ...

... a single 24hour period. Rather, the consensus has been that child growth was divided into three stages (infancy, childhood, adolescence), each characterized by different, but steady rates of growth. This conclusion was based upon annual and quarterly length measurements. However, when children are measured more often (weekly or daily), the growth curve is seen to be step-like rather than smooth, as in the accompanying illustration. Indeed, the mean amplitude of the growth spurts was found to be about 1 centimeter; and the duration of the spurts, about one day. These spurts punctuated long intervals of no growth. In infants, for example, 90-95% of their development is growth-free! (Lampl, M., et al; "Saltation and Stasis: A Model of Human Growth," Science, 258:801, 1992.)

... designated Early Archean and assigned an age of 3.465 billion years [Four significant figures!]. It is rare to find any fossils at all in rocks this old, but apparently the Apex chert escaped most of the fossil-destroying metamorphism afflicting most Precambrian formations. Even more remarkable is the diversity of these suspected bacteria. J.W . Schopf reports finding no less than eleven different kinds so far--and our planet was only a few hundred million years old at the time the Apex chert was formed. Schopf's discoveries generate at least three questions: How could life have originated and diversified to such an extent in just a few hundred millions years? Why after such rapid diversification did these microorganisms remain essentially unchanged for the next 3.465 billion years? Such stasis, common in biology, is puzzling. If these microorganisms are really cyanobacteria, they would have released oxygen to the atmosphere. Is the standard assumption that the earth's atmosphere lacked oxygen until 2.2 billion years ago correct? (Schopf, J. William; "Microfossils of the Early Archean Apex Chert: New Evidence of the Antiquity of Life," Science, 260:640, 1993. Also: Pendrick, D.; "Fossils Show Early Diversity of Life," Science News, 143:276, 1993.) From Science Frontiers #88, JUL-AUG 1993 . 1993-2000 William R. Corliss ...

... , is: "The most thorough study yet of species formation in the fossil record confirms that new species appear with a most un-Darwinian abruptness after long periods of stability." In the article that follows, R.A . Kerr reviews several recent studies of fossil bryozoans and snails. Some of these painstaking dissections of the fossil record were carried out by scientists initially committed to Darwinian gradualism. Even these researchers have been forced to acknowledge that much biological evolution proceeds not in minute steps but by large jumps or saltations. Such abrupt speciation is tough enough to explain, but even more daunting are those species untouched by change over millions, even hundreds of millions of years. Indeed, the major characteristic of the fossil record and, therefore, earth life as a whole, has been stasis rather than speciation, despite all manner of asteroid impacts and climatic traumas. Nevertheless, many biologists think that species are somehow frozen in time by environmental forces that keep them from straying from their little niches. This being so, paleontologist D. Jablonski, University of Chicago, asks: If stability is the rule, how do you get large-scale shifts in morphology? How do you get from funny little Mesozoic mammals to horses and whales? From Archaeopteryx to hummingbirds? (Kerr, Richard A.; "Did Darwin Get It All Right?" Science, 267:1421, 1995) Comments. (1 ) The reality of sudden saltations in the fossil record or "punctuated equilibrium" implies that those unfound transitional fossils beloved by the gradualists are truly missing. (2 ...
