Where did the primate line that led to man really originate? Lately most of the evidence has pointed to Africa, where scientists have found the bones of a knuckle-walking ape called Dryopithecus, a creature that lived some 20 million years ago and is generally believed to have given rise to both apes and man. This ape's own ancestors seem likely to have lived in Africa as well. As Exhibit A, Duke University Anthropologist Elwyn Simons offered fossils, found near Cairo, of a tree-dwelling primate 30 million years old; Simons christened the creature Aegyptopithecus. Last week, however...
...telltale fossils, as described by Paleontologist Donald Savage of the University of California, Berkeley, and Anthropologist Russell Ciochon of the University of North Carolina, Charlotte, are four lower-jaw fragments. They were found in an ancient seabed in the Pondaung Hills west of Mandalay, embedded below a layer of marine organisms called foraminifera, dating from about 40 million years ago. Associated with the find were other fossils of animals known to have lived during the same period, lending more weight to the fragments' apparent place in time and indicating that the Pondaung Hills had also supported lizards, several kinds...
...fossil bones and teeth were not, in fact, the first fragments found in the area. During the 1920s, before Burma broke away from British domination and became an independent country, scientists found similar specimens. The fossils were poorly preserved, but they seemed to represent two slightly differing kinds of primates that were named Pondaungia and Amphipithecus, and their discovery persuaded some anthropologists that the roots of the higher primates lay in Asia. Of the new fragments, all but one have been matched with the original finds...
Unfortunately, no amount of synthetic periplanone B is apt to stimulate an entire roach species into extinction. As rueful scientists have found in using pesticides, a few hardy roaches can usually survive a chemical spray because of some lucky genetic abnormality and will then propagate a new generation of spray-resistant offspring. Declares Entomologist Louis Roth, a pioneer in roach research: "The best we can hope for is to reduce their numbers...
...Despite the name, the German cockroach, Blatella germanica, is probably mostfamiliar to U.S. city dwellers as a kitchen nemesis. The American roach is often found where food is stored...
