...state. In Washington, the Senate has authorized an admittedly superfluous third federal judge for Utah, and a House subcommittee has approved repeal of a grandfather clause, which could also cost Ritter his power to assign cases. (Congress exempted 32 sitting chiefs of two-judge districts when it mandated an age 70 retirement policy in 1958; now Ritter is the sole survivor.) Either step would please Utah Senator Jake Garn, who brands Ritter "a disgrace to the federal judiciary...
...that the earlier finds were not the remains of a freak ape or a deformed human. The ancient, erect-walking creatures had apparently been plentiful and widely distributed; it now seemed indisputable that modern man had evolved from more primitive ancestors. But still not even those who acknowledged his age had any clear notion of man's antiquity. Even the evolutionists saw the whole course of human development as a fairly recent phenomenon, and no one had any real conception of its causes...
Chemist Willard Libby. This was followed by the invention of the potassium-argon method. Both gave scientists techniques by which they could accurately determine the age of the strata in which fossilized bones were found, and sometimes the age of the bones themselves. Using these new tools, they have determined that Java man and Peking man, now classified as Homo erectus, walked the earth more than 500,000 years...
...threshold of humanity. "1470" after its National Museums of Kenya catalogue number, was manlike in configuration and, according to Leakey's measurements, once contained a brain of 800 cc.?more than half the average size of a modern human brain. But what excited the team most was the age of the skull. Probably a Homo habilis, 1470 was more than...
...proved that Homo habilis?from whom man could have descended?coexisted with Australopithecus, thus weakening arguments that the latter was man's direct ancestor. Then, in 1975, the Turkana site yielded a Homo erectus skull resembling that of Peking man and with a brain size of 900 cc. The age of the fossil, about 1.5 million years, showed that Homo erectus had emerged even earlier and was hunting in the African plains while Australopithecus still roamed the earth. Because the more advanced Homo erectus was almost certainly a direct ancestor of modern man, the new skull, in the view...
