But don't uncork the champagne yet, because molecular clocks are not like Big Ben. Here's what has happened: A. Torroni and some colleagues at Emory University have analyzed the mitochondrial DNA (mtDNA) of members of seven linguistically related tribes in Central America called the "Chibcha speakers." Assuming that the homogeneous group separated from the other Amerind tribes 8,000-10,000 years ago, the Emory group found that their mtDNA had mutated at the rate of 2.3 -2 .9 % per million years. (Note: this works out to 0.0022-0 .0029% per thousand years -- a very small amount to measure accurately!) Next Torroni et al measured the mtDNA of 18 other tribes throughout the Americas and, using the mutation rate just mentioned, computed how long ago these peoples had diverged from a common ancestor. The result: 22,000-29,000 years ago. The Emory study was published in the February 1, 1994, issue of the Proceedings of the National Academy of Sciences . All this is very well, but suppose that the tribes had ...

Lovecraft could certainly come up with an ominous entity based upon RNA alone. Be that as it may, a book is now on the market bearing the title The RNA World (R .F . Gesteland and J.F .

We now extract one nugget from each of these two sources. From Nature's review.

In connection with the generally accepted idea that the evolution of RNA must have taken hundreds of millions of years: ". .. de Duve suggested that, on the contrary, for such a complex chemical process to succeed it must have been relatively fast in order to avoid decay and loss of information."

Now, it is challenging archeological sacred cows using mitochondrial DNA. Quite a switch from pork futures! Of course, the WSJ is not a recognized scientific source, but its reporter did get his information directly from D.C . Wallace, a well-known professor of genetics and molecular medicine at Emory University and a champion of the African Eve theory. Surely an unusual illustration for the archeology section, but the DNA in these mitochondria may upset long-held theories of human migration. Anyway, Wallace has been studying mitochondria, those little energizers in human and animal cells. Strangely, mitochondria have their own DNA, which is separate and distinct from the nuclear DNA that directs other biological processes. Mitochondrial DNA has had its own history of evolution and is different for various human populations. Wallace has used this fact to trace the origins of American Indians by comparing their mitochondrial DNA with that from Asians, Africans, etc. His conclusions are controversial to say the least. The Amerinds, who comprise most of the Native Americans, arrived in a single migratory wave 20,000-40,000 years ago -- not merely 12,000 years ago! Native Siberians lack a peculiar mutation of mitochondrial DNA that appeared in the Amerinds 6,000-10,000 years ago ...

... influences," writes [R .] Greenspan, "but also the highly interconnected network of the nervous system sets up an additional layer of complexity between the gene and the realization of the phenotype." (Ref. 1) Many genes code for multiple variants of the same protein. And many proteins are modified by adding sugar molecules, which play a big role in determining where proteins go and what they do. What's more, different proteins can join together to carry out completely new functions. (Ref. 2) A group of French biologists, led by Francois Jacob and Jacques Monod showed that the gene's boundaries are fuzzier than had been thought and that genes are not restricted to chromosomes. Recently, biologists have found genes within genes, overlapping genes, and DNA sequences that specify one protein when read "forward" and another when read "in reverse." Muddling things further, the instructions encoded in the DNA do not always reach the ribosome as a literal translation. In a phenomenon known as RNA editing, an enzymatic highwayman intercepts the RNA message en route and alters it, so the resulting protein is not identical to that specified by the DNA. (Ref. 3) We can sum up by saying that a lot can happen to that information encoded in the genome before it is put to use. References Ref. 1. Anonymous; "The Flexible Genome," Nature, 411:xi, 2001.

It is widely accepted as fact that all women are de-scended from an African "Eve" who lived between 100,000 and 200,000 years ago. This conclusion was based upon mtDNA (mitochondrial DNA) studies that assume that mtDNA is inherited only from mothers. This assumption has been repeated so often that few ever question it. However, two recent studies seem to show that some paternal mtDNA actually does get into eggs and recombines with maternal mtDNA. This unexpected invasion makes the mtDNA clock run more slowly. So, African Eve, if she ever existed, is probably twice as old as originally thought. (Day, Michael; "All about Eve...," New Scientist, p. 4, March 13, 1999.) Maybe There Were Two Eves! Not only has African Eve aged precipitously but there may have been a non-African Eve, too. J. Hey and E. Harris, at Rutgers, have presented data suggesting that the famous African Eve was the mother of only modern sub-Saharan Africans. Everyone else seems to have descended from an entirely different Eve. These data, if confirmed, demolish the African Eve theory and support the often-reviled multiregional theory of humans origins.

... pork or piglike animals." As the author of the above words, N. Wade, is quick to point out, there are several other groups of people around the world who practice Judaic rites or claim to be of Jewish ancestry but have no provable ancestral connections. The Lemba, however, also have a genetic tie. Lemba males carry a distinctive set of genetic mutations in their Y chromosomes. This particular genetic characteristic is strongly associated with the cohanim, the Jewish priests said to be descendants of Aaron. This genetic trait is less common among lay Jews (only 3-5 %) and very, very rare among non-Jews. This "cohen genetic" signature (cohen = priest) is considered diagnostic of populations of Jewish ancestry.

Now, a second kind of gene switch has been discovered on histones, a class of proteins. Figuring out when methylation of histones takes place has far-reaching implications; acting as a second genetic code, histone methylation may determine genetic traits such as the susceptibility to disease. (Martindale, Diane; "Genes Are Not Enough," Scientific American, 285:22, October 2001.) Comment. So, beyond the first genetic code (the DNA) and the second genetic code (the recognized methyl groups), we now have some proteins (the histones) getting in on the act. And the show ain't over yet!

Some of the genetic differences between humans and chimps seem to belie that miniscule 1.5 % difference everyone bandies about. To illustrate, humans have only 46 chromosomes, while the great apes all have 48. The 1.5 % figure doesn't hint at this significant difference. Next, take a look at chromosome #9 in humans and the great apes. Chromosome bandings are different enough to raise further suspicions about the 1.5 % figure. (Gibbons, Ann; "Which of Our Genes Make Us Human?" Science, 281:1432, 1998.) Comments. It is easy to see how gross comparisons of DNA might miss important details. The popular "DNA-hybridization" method simply mixes together strands of DNA from the two species being compared. These are allowed to combine, and then they are heated to see how much temperature is required to force them apart. Chromosome numbers and bandings have little if any effect on these crude comparisons of the bare DNA strands that have been stripped from their genes and chromosomes. The significance of all this transcends the comparisons of humans and chimps. Modern taxonomy of all life forms depends increasingly upon DNA comparisons rather than upon morphology. If DNA comparisons can be as misleading as they are in humans and chimps, those textbook family trees that are supposed to tell us how life evolved may also be giving us an erroneous history of life.

Only when we get the flu or infected finger do these entities impinge upon our consciousness. Below we will learn that there are many more of them than you think. Do viruses control the oceans? You may avoid the beaches after you learn that one teaspoon of seawater typically contains 10-100 million viruses and onetenth that many bacteria. Obviously, most are harmless to humans. However, the viruses do infect the bacteria and phytoplankton, destroying them, and thereby releasing their nutrients. By doing this, they keep the oceans' biological engines running. Further, the viruses act as genetic engineers as they transfer DNA from one individual to another. The oceans may be viewed as vast test tubes in which biodiversity is maintained by teeming, invasive viruses. (Suttle, Curtis A.; "Do Viruses Control the Oceans?"
