Also, the notion that man became bipedal in tandem with his brain growth is no longer widely held. (More likely, changing survival needs led him out of the jungle to the African savanna, where he stood to peer over tall grasses.) As for Johanson's announcing a "new" name for Lucy, some specialists observe he did that a year ago in a little-noticed Cleveland Museum journal. "I don't think Johanson has made a particularly good case for her being a different species," says a leading anthropologist, and adds...
...changing food supply offered new opportunities for feeding outside the forest. Some of the forest-dwelling apes began venturing into the savanna, or grasslands, in search of food such as roots, seeds and finally the meat of other animals...
...erect position enabled them to see over the tall grass to spot and hunt their prey?and to see and escape the carnivores that preyed on them. Thus they were able to survive longer and produce more offspring, who shared their physical characteristics. After many generations of selection, the savanna-dwellers had evolved into upright-standing animals distinctly different from the forest-dwelling relatives they had left behind...
...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, on the other hand, continued to subsist largely...
...annexed by Selassie-an action that the Eritreans still regard as outright colonialism. Their outrage sparked a tiny guerrilla uprising that eventually became a full-scale war, perhaps the largest war now being fought anywhere in the world. In the process, reports TIME Correspondent Dean Brelis after touring the savanna and highland battlefront, the Eritreans have built an extraordinarily effective fighting machine of at least 25,000 men equipped with artillery and rockets. They control at least 85% of the province and all but 300,000 of its people, and their eventual victory appears assured. Says Ahmed Mohammed Nasser...
