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. It now seems that the regions once ...

Science Frontiers ONLINE No. 139: Jan-Feb 2002 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Really High Oysters At 12,300 feet of altitude among the cold rarefied peaks of the Andes, one would not expect giant fossilized oysters. But there they are---over 500 of them in one location. Some are 3.5 meters in circumference (about 3.8 feet across). When alive, they probably weighed 300 kilograms (660 pounds). About 200 million years ago, according to the geologists, these oysters were thriving under Pacific waters. One must conclude that the Andes rose to their snowy magnificence in a very short period of geological time. (Mayo, Raul; "Descubren Fosiles de Ostras Gigantes en Plena Cordillera," El Comercio, February 28, 2001. Cr. R. Gabbert) Comment. The article calls the fossils "oysters" (" ostras"), but they look more like giant clams. The high Andes boast some curious marine innuendoes. Lake Titicaca is freshened by melting snows but is said to support a species of seahorse and many fish with marine affinities. It drains into lakes that are highly saline.
