Bomb explodes PP .at. Texas petrole *um pant BAYTOWN, Texas (AP)- A bomb exploded yesterday at a Gulf Oil Co. petrochemical plant as it was being deactivated, authorities said. Four other bombs were found in the apparent extortion attempt and safely deac- tivated. No injuries were reported -as the ex- plosion occurred while authorities used a water cannon on the device, said the Texas Department of Public Safety. No details of the operation, or the com- position of the bomb, were released. THE FIVE devices were being deac- tivated at the sites where they were discovered on the plant grounds when the bomb exploded, according to Sgt. W.D. Marsh of the department. Authorities were continuing to search for other bombs, Marsh said. Company officials and authorities refused to comment on reports of a warning that 10 bombs would be detonated if a demand for up to $15 million was not met within 120 hours. THE DEADLINE would be about noon Sunday. An unofficial source said. the bomb threat was in a seven-page letter that specified the location of one of the 10 bombs and said four others could be found easily, The Baytown Sun repor- ted. The source said those were the five bombs found. The Michigan Daily-Friday, October 1, 1982-Page 5 Prehistoric human being discovered in Israel NEW YORK (AP) - A new study concludes that a prehistoric human an- cestor lived in Israel 500,000 years before appearing in Africa, challenging the prevailing view that the human race originated in Africa. The finding does not necessarily mean that the ancestor, known as Homo erectus, evolved in Israel, says the study's author, Charles Repenning of the U.S. Geological Survey in Menlo Park, Calif. "It's conceivable that he evolved elsewhere and was on his way to Africa when he died in Israel," Repenning said yesterday in a telephone interview. DAVID PILBEAM professor of an- thropology at Harvard University, called Repenning's finding "a sur- prising result." Pilbeam said he has not seen Repenning's study, which ap- pears in the current issue of Nature magazine. Pilbeam said the finding is "feasible," but that it is contradicted by a substantial body of circumstantial evidence that hominids - humans, their direct ancestors and their extinct cousins - evolved in Africa., One important reason for thinking so, he said, is that a large number of 4- million-year-old fossils have been found in Europe and Asia, and no hominids have been among them. REPENNING agreed that the australopithecines - the ape-like an- cestors of Homo erectus - evolved in Africa. "But they got out of Africa and Homo evolved somewhere else, accor- ding to the Ubeidiya story," he said,' Repenning based his conclusions on7 re-examination of animal fossils found- at an archeological site called' Ubeidiya, two miles south of the Sea of Galilee and west of the Jordan River. Stone tools associated with Homo' erectus have been found there and judged to be about 700,000 years old.e Similar tools thought to be 1.5 million, years old have been found in ex- cavations in Tanzania and Kenya. The explanation has been that Homo erec- tus, who presumably made those tools; lived in Africa hundreds of thousands of years before he migrated to Israel. Marine killed in Beirut (Continued from Page 1) the Marines, who had been deployed in Beirut earlier this summer to help oversee the evacuation of Palestine Liberation Organization guerrillas from the Israeli-ringed city. The Marines returned Wednesday on their second peacekeeping mission. PRESIDENT Reagan reacted with "shock and sorrow," but said the casualties would have no effect on the U.S. commitment to remain in Lebanon until Israeli and Syrian troops ae out and the government is in control, White House deputy press secretary Larry Speakes said in Washington. Pentagon spokesman Henry Catto said in Washington the blast was "just an accident," not the result of hostile action against U.S. forces. The victims were immediately flown to the U.S.S. Guam, the helicopter carrier that serves as flagship for the U.S. fleet supporting the Marines in Lebanon., ONE MARINE died after reaching the Guam, another was seriously wounded and the other two were slightly wounded - one with a leg wound and the other with an arm explosion wound, DeLorme said. Their identities were withheld, but the Lebanese army siad the dead man was an officer. U.S. officials said about 300 Marines came ashore yesterday, bringing to 1,200 the strength of the U.S. force guarding the airport and surrounding areas. the university of michigan center for chinese studies presents Just pull the string The cards shown are not a mock-up of state placards at a political conven- tion, but rather parts of an art display by Kathy Constantinedes at the Slusser Gallery in the art school. the work, entitled "Karnak Dissolve," in- vites each visitor "to pull enough thread to release one word, and to take the word away."~ n 5191. *Congress fails to set 1983 budget, parties instead (Continued from Page 1) the resolution will be in effect only until Dec. 17. After that date, the new Congress would have to vote on their own appropriations. "Then anything can happen," he said. Edwin Dale, a spokesman for the Of- fice of Budget and Management, said no disruption in operations is likely, provided Reagan accepts the com- Sromise. Nevertheless, Dale said all gover- nment agencies were notified yester- day to begin "shutdown" operations today. ALSO IN Congress this week, the House voted in favor of a resolution to' keep the Basic Educational Oppor- tunity (Pell) Grant 1982-83 family coil- tribution schedule for the next academic year. This schedule determines what amount of discretionary income families are expected to contribute to education, and therefore determines the amount of aid a grant candidate is eligible for. The bill awaits Reagan's signature or veto, Although agreement on the com- promise bill came several hours before the midnight deadline, congressional leaders decided against a late-night session to pass the measure on an evening when major social events were scheduled for both Democrats and Republicans. THE DEMOCRATIC party had a $1,000-per-person fund-raising dinner that many members of Congress were expected to attend. Anq President Reagan invited the entire Congress to a barbecue at the White House in what amounted to a counter-event dominated by Republicans. The stopgap spending plan will keep the entire government in business until Dec. 17, thereby assuring a post- election session of Congress in which lawmakers will debate the regular money bills that have not yet been ap- proved.
