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.

According to the "African" view, modern humans arose exclusively in Africa and, about 100,000 years ago, expanded rapidly from there into Europe and Asia, displacing "lesser" hominids. Unfortunately, the DNA studies that stimulated this conjecture have been found to be flawed. And now new fossil testimony casts further doubt. In 1989 and 1990, near the Han River, in China's Hube Province, anthropologists found hominid skulls with the characteristic flat faces of modern humans. These skulls seem to be about 350,000 years old. Although they apparently retain some primitive features, paleoanthropologist D. Erler, of the University of California, asserted, "This shows that modern features were emerging in different parts of the world." In other words, all of the evolutionary action was not confined to Africa. Proponents of the "African Eve" theory retort that the dating of the Chinese skulls is questionable and that flat faces alone are not enough to support the idea that modern humans arose separately in widely separated locales?

Williamson has scrutinized the distribution of some 190 faunas with high stratigraphic resolution; that is, he believes he has been able to sketch for the first evolutionary events on a fine time scale. Williamson underlines three important observations: (1 ) Species seemed to arise suddenly, as predicted by the "punctuated evolution" model; (2 ) The formation of new species was accompanied by marked developmental instability in the transitional forms; and (3 ) All lineages were morphologically stable for long periods -- they did not change form! The biological implications of this important study are summarized in the preceding item. (Williamson, P.G .; "Palaeontological Documentation in Cenozoic Molluscs from Turkana Basin," Nature, 293:437, 1981.) Comment. Evolutionists have often bewailed the obvious lack of transitional forms (missing links) in the stratigraphic record. According to Williamson's results, transitional forms would be few in number and display considerable morphological instability. In essence, this means that missing links may not exist in a practical sense. If this is true, one wonders whether those famous evolutionary family trees in all the textbooks, such as that of the horse, are really misleading.

We have heard for so long now that modern humans got their start in Africa. (This assertion is as hackneyed as: "Life began in a warm little pond"!) There is, of course, some evidence for the African claim. Studies of genetic material and the fossil record are suggestive, although the latter includes the Middle East as a possible birthplace. Other data, however, put the "founding group" of modern humans in Southeast Asia. The iconoclast here is C.G . Turner, II, an anthropologist at Arizona State University. He has analyzed secondary dental traits (number of roots, bumps, etc.) of 12,000 individuals from around the world - both ancient and modern. Turner believes that the "great web of humanity" originated in Southeast Asia. Since then, two large populations, each recognizable by their dental features, have evolved.: (1 ) northeast Asians and the ancient residents of the Americas; and (2 ) southeast Asians, Europeans, ancient Australians, and Africans. Also of note is the close resemblance between native Australians and Africans. (Bower, B.; "Asian Human Origin Theory Gets New Teeth," Science News, 136:100, 1989.)

"It has been suggested that the evolution of man took place in Africa. This suggestion results from the unusual abundance of fossil material in Africa that is quite ancient in comparison with what is known elsewhere. The theory of an African origin has influenced the interpretation of the age of some non-African archaeologial sites. A case in point is the 'Ubeidiya locality in Israel, which is generally considered to be about 700,000 yr old because it has been assumed by a few that the associated Early Acheulian tool industry, and the persons who used it, would have taken considerable time to disperse from Olduvai Gorge to this non-African site in Israel. Here we evaluate fossil mammals from 'Ubeidiya, which are stratigraphically and directly associated with Early Acheulian artifacts, and find no substantial reason for considering the locality younger than 2Myr, and possibly as much as 500,000 yr older than any record of Early Acheulian artefacts or Homo erectus in Africa."

Sea levels were lower 900,000 years ago, but Flores was still 19 kilometers away. How did our ancestors cross this water barrier? There is no evidence whatsoever that these hominids built boats. How about simple rafts? Possibly, but there is another way. They swam the 19 kilometers (12 miles)! Many modern humans can paddle this far and it seems reasonable that ancient peoples could, too. Another water barrier may have been crossed by African swimmers a million or so years ago. Their artifacts are found in southern Spain. Did they swim across the Strait of Gibraltar rather than trek the long land route through the Middle East and across mountainous southern Europe? These possible aquatic feats of our ancestors are not in themselves enough to strongly interest an anomalist but when they are coupled to another recent discovery they add weight to a much more fascinating speculation that early hominids were once marine mammals -- or at least nearly so. More important to this radical thesis than human swimming prowess is the recent scuttling of of the vaunted paradigm that modern humans began evolving only when they split from the forest-dwelling primates and invaded the African savannahs.

"Molchanov's controversial evidence is indeed striking: a collection of chipped and flaked rocks that are clearly artifacts fashioned by humanlike hands and that he contends are 2.5 million years old -- plus or minus a half-million years. "Remarkably, that same era marked the time when early human ancestors known as Homo habilis lived and left their remains in the tropical Olduvai Gorge of what is now Tanzania. Mochanov's collection of tools closely resembles the ones that anthropologists have long collected from digs in Africa." All this contrasts strongly with the dominant view of hominid evolution, which cites warm, verdant African forests and savannas as our most likely place of origin. Siberia, with its -50 winters and fleeting summers, hardly seems conducive to hominid speciation. Mochanov's rationale is that this severe climate actually stimulated ancient hominids to create tools, fashion warm clothing, and build winter shelters -- these Siberian hominids had to evolve or perish! In addition to the climate factor are two other problems: (1 ) The Siberian sites have yielded no hominid bones nor have animal bones of any kind been found; and (2 ) The dating of the tools is shaky. They cannot be radiometrically dated. Instead, Mochanov has had to rely on the tools' similarity to African tools of 2 million years ago, magnetostratigraphy, the decayed luminescence of the soil, and the ages of ...

Although numerous megalithic circles and other arrangements are known in Africa, particularly Ethiopia, astronomy does not seem to have been a primary objective of African sites. Now, however, a stone alignment in northwestern Kenya called Namoratunga has been found with unmistakable astronomical overtones. At Namoratunga, 19 large basalt pillars are arranged in rows forming a suggestive pattern. Since the site is dated at approximately 300 B.C ., archeologists have taken sightings on seven prominent stars as they would have appeared during this period. (The azimuths of some of these stars had changed by as much as 12 in 2,200 years.) The stars chosen are those employed by Eastern Cushites, the present inhabitants of the region, in calculating their rather sophisticated calendar. Pairs and frequently triads of these pillars line up very accurately (to less than 1 ) with the seven key stars. The people occupying this part of Kenya about 300 B.C ., therefore, probably possessed detailed astronomical information.

This human skill, again unique among primates, is obviously quite ancient. Furthermore, recent experiments suggest that in humans, in addition to seals and ducks, vascular constriction is not limited to the arterioles but extends to the larger arteries, too. This indicates some degree of specialized adaptation to a diving life. Most animals with a sodium deficiency display an active craving for salt which, when satisfied, disappears. In humans, salt intake has little or no relation to the body's needs. Some Inuit tribes avoid salt almost completely, while people in the Western world consume 1520 times the amount needed for health. In other works, a single African species (assuming humans have an African origin) possesses a wildly different scheme of salt management. Humans are also the only primates to regulate body temperature by sweat-cooling, a system profligate in the use of sodium. Proponents of the Aquatic Ape Hypothesis believe that sweat-cooling could not have developed anywhere except near the sea where diets contain considerable salt, in fact much more salt than the body requires.

While the Lake Victoria cichlids seem to have evolved a profusion of species in a space of about 12,500 years, those cichlids in Lake Malawi may have done the same in only a century or two. T. Goldschmidt advances this evenmore-abbreviated time scale in his book Darwin's Dreampond . In it, he discusses how the water level of Lake Malawi fell more than 120 meters during the 1800s -- an exceptionally dry period in Africa. Today, the Lake is again high and once more host to isolated rocky islands, each with its own unique complement of cichlid fish; each island has species found nowhere else in the lake. Where did all these species come from, considering that their little islands were bone dry just a century ago? Goldschmidt writes: "Cichlids that inhabited these exposed rocks would have suffocated, unless they had already left for wetter climes. Yet today, species that do not exist anywhere else can be found near almost every rocky island.

... Flamingo's Smile," like all his writing, is thought-provoking. 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, some of which were just what was needed for efficient upside down feeding. In this way, we end up with admirably adapted, inverted flamingos, jellyfish, and catfish. (Gould, Stephen Jay; "The Flamingo ...

After lengthy cooling periods, the crystalized diamonds were transported to the surface by fluid, lower-melting-point rocks, such as kimberlite. Many South African diamonds are mined from kimberlite pipes. Diamonds are never pure carbon; they always contain some nitrogen and boron. Occasionally, they harbor tiny radioactive impurities; usually alpha-particle emitters in the uranium-238 decay chain. Alphas emitted by these impurities have well-defined energies and penetrate the diamond matrix only so far. If one examines a diamond with a high-power microscope (say, at 100 x), one can see concentric rings surrounding the impurities. These dark radiohalos or "pleochroic" halos have specific radii and can be used to identify the radioisotopes that produced them. So far, so good; but: "The fact that fully formed, optically visible internal radiohalos in diamonds are now presented casts a considerable shadow over current theories of diamond genesis." Actually, the radiohalos pose three challenges to diamond-genesis theory. Problem 1. The half-lives of the halo-creating radioisotopes are measured in thousands of years rather than the billions prescribed for crystallization. ...

Yet, Precambrian oil in commercial quantities has been found in formations up to 2 billion years old (in Siberia, Australia, Michigan, for example). While some of this oil might have migrated in-to the Precambrian rocks from younger source rocks, some of it does seem indigenous and, therefore, ancient. (SF#48) Now, three Australian scientists (R . Buick, B. Rasmussen, B. Krapez) have discovered tiny nodules of bitumen (lumps of hydrocarbons) in sedimentary rocks up to 3.5 billion years old in Africa and Australia. These bitumen nodules were formed when natural hydrocarbons were irradiated by radioactive isotopes that coexisted in the ancient rocks. Futhermore, these African and Australian rock formations were never severely deformed or subjected to high temperatures. The possibility exists, therefore, that some of the earth's oldest rocks may contain substantial oil reserves. So far, no one has seriously looked for oil in Precambrian rocks because of the two preconceptions noted above. (Palmer, Douglas; "Any Old Oil?" New Scientist, p.22, March 14, 1998.) Comments.

Just about everyone believes that tektites are once-liquid droplets of rock that were solidified in flight. The major question -- often intemperately debated -- is the location of the tektite source. Are they of terrestrial, lunar, cometary, or some other origin? A recent study by Shaw and Wasserberg, using element abundances as a guide, strongly favors a terrestrial origin, with meteor impacts serving as the liquefying and splashing agents. Indeed, specific craters have long been associated with the European and African strew fields. Those who believe that the tektites were splashed all the way from the moon by meteor impacts have not given up yet. One provocative fact stressed in this article is that the ages of the four groups of tektites are 35, 14, 1.3 , and 0.7 million years. Tektites are all quite young!

A little excavation work uncovered small pockets, a few meters in length and less than a meter in width, where natural fission had occurred in the Precambrian period.

For example, one scene painted on the tomb of one pharaoh represents tributes brought from afar to Egypt, including a parade of exotic animals. One of these animals is an obvious bear. This animal would have intrigued the pharaoh because bears and ancient Egyptians did not coexist. Just as exotic to the pharaoh would have been the miniature elephantid following just behind the bear in the painting. It was about the same size as the bear. Since this elephantid was depicted with large tusks, it was definitely not an immature. It also displayed the peculiar domed skull typical of mammoths and which is absent on African elephants.

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.

Wouter Van Hoven says that acacias nibbled by antelope produce leaf tannin in quantities lethal to the brows ers, and emit ethylene into the air which can travel up to 50 yards. The ethylene warns other trees of impending danger, which then step up their own production of leaf tannin within just five to ten minutes." (Hughes, Sylvia; "Antelope Activate the Acacia's Alarm System," New Scientist, p. 19, September 29, 1990.) Free-ranging antelope can always find unwarned acacias with low levels of tannin to browse on, but on some South African game ranges, they are forced to consume high tannin leaves.

Breiner wields a magnetometer when he searches for Olmec artifacts. This instrument allows him to detect buried objects, and he has made some surprising discoveries. The Olmecs flourished circa 1,500-400 B.C . in Mexican states of Vera Cruz, Oaxaca, and surrounding areas. This enigmatic culture is probably best known for the giant stone heads they carved out of hard rock. These massive heads, 8-15 feet high, seem to display African features. Breiner has found two of the 17 known heads. The most interesting one weighed 10 tons and was buried 18 feet deep! Why would a thriving culture bury the product of so much intensive labor? (Robinson, Dave; NEARA Transit, 11:12, Spring equinox 1999. Item attributed to New York Times, May 26, 1998.) Comment. The burial of the Olmec head might have had ritual significance, like the ritual smashing of pottery or the sacrificing of animals. Be this as it may, we wish to connect the Olmec heads with the large stone spheres found in Costa Rica, just a few hundred miles down the Pacific Coast. The Costa Rican spheres are also beautifully and laboriously crafted from hard rock. Many are several feet in diameter. The curious part is that many of them were also buried in the jungle soil like the Olmec heads. They were exhumed only when banana plantations were established. ...

Science Frontiers ONLINE No. 89: Sep-Oct 1993 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Why do electric fish swim backwards?This is not a trick question like the one about the chicken crossing the road. To understand the answer to the electric fish puzzle, we must restrict the discussion to those fish with active electric sensing systems. This group includes electric eels, South American knife fish, and African elephant snout fish. All of these have evolved, in a remarkable instance of parallel evolution, the capability of generating pulses of electricity. These pulses (up to 1,000 per second) radiate through the surrounding water. Prey and other nearby objects distort these oscillating electric fields. Electroreceptors on the fish and a sophisticated data processing system convert the field distortions into an "image" of the surroundings. M. and S.J . Lannoo, of Ball State University, have watched the black ghost knife fish, which plies murky Amazon waters, approach likely prey tail first. Swimming backward using an elongated belly fin, the knife fish slowly cruises past its potential victim. If the electrical image looks appetizing, the knife fish grabs its dinner with a forward lunge as it appears in front of it. "The researchers suggest that the fish swims past objects in order to scan them with its electroreceptors. This is the only way the fish can identify prey because an electric sense cannot be focussed like an eye. But if the fish carried out its scan by swimming forwards, the prey would end up ...

... reference line constitute alphabetical symbols. The ancient Irish are credited with inventing Ogam; and Ogam inscriptions are common in that part of the world. During the last two decades, B. Fell and members of the Epigraphic Society have discovered many possible Ogam inscriptions in the continental United States. In fact, the latest issue of the NEARA Journal (NEARA = New England Antiquities Research Association) contains two articles dealing with supposed Ogam writing and other crude drawings in the Anubis Caves of western Oklahoma. The presence of true Ogam writing in Oklahoma would be traumatic for mainstream American archeology, for it would imply that far-wandering Celts had passed through long before Columbus made landfall. Later in the same issue of the NEARA J., G. Carter describes a tablet in the possession of a South African Zulu, which pictures a giraffe and a zebra along with inscriptions in Egyotian, Arabic, and Ogam! Carter writes: "I put below of picture of a giraffe with Ogam alongside. The Ogam letters are RZRF. Add vowels and this becomes: Rai Za Ra Fa; old Arabic for 'behold the giraffe.' Alongside a zebra figure one finds Ogam letters ZBDB, which in Arabic reads 'painted ass.' These animal figures are usually considered to date to the Upper Paleolithic. Apparently Arabic speakers added the inscriptions much later. But when, pray, did the Arabs write in Ogam? Those Celts certainly did get around! Has anyone found Ogam in South America or Australia?
