Scientists believe they are closing in on the time when this earliest form of man emerged. Fossil evidence shows the split that produced the first human must have occurred longer ago than 3.5 million years?the age of the oldest known Homo fossils, which were found in 1975 by Mary Leakey. Again, the rigorous demands of savanna living may have been responsible for the branching out. Australopithecus africanus, straining to augment its food supply in the flat grasslands, began to eat meat?probably obtaining it not by hunting, but by scavenging the kills left behind by large predators. Australopithecus robustus...
...sense, Leakey was born for his role. From the age of six months, he was taken on expeditions with his famous parents and learned to recognize fossils almost before he could talk. His childhood conversations were filled with the anatomical, geological and biological jargon of anthropology. His father ?a Church of England missionary's son who was raised almost entirely in the African bush?taught "bushcraft" to Richard and his brothers Jonathan and Philip by sending them out to scavenge and survive in the wild. But as Richard grew up, he became restive living in the shadow of strong...
...years Richard had escorted visiting scientists to his parents' dig at Olduvai and taken them around East Africa on courtesy safaris. In 1960, at the age of 17, he left school without graduating and set up a safari business on his own. The business did well, but Richard soon yearned to be back in the digs. Then, in 1963, on a chance flight over Lake Natron in northern Tanzania, he spotted what looked like interesting sediment beds and, encouraged by his parents, set off to explore the area. His first expedition proved to be a success; the team he assembled...
Interpreting these finds requires even more skill. The age of a fossil can often be determined by analyzing the layer of rock or soil in which it was found and determining, often by the so-called potassium-argon method, just how old the layer is. Interpreting the messages of the fossil is usually more difficult. ; The first step in studying a fossil, ; which is often fragmented, is to separate -it from its rock or soil matrix. Next the ! fragments are assembled, a task considerably harder than putting together a jigsaw puzzle with pieces all the same color...
...papal politics. Of the 117 voting members of the College of Cardinals?which only meets to elect a new pope?51 were Synod delegates. Thus the Synod provided an opportunity for nearly half of the papal electors to observe one another in action for weeks. Given Paul's age, the 1977 meeting could well be the last Synod before the next papal election is called...
