...surprising first of all that anything was alive that far back," J. William Schopf, Junior Fellow, and co-discover of the fossil along with Elso S. Barghoorn, professor of Botany, said yesterday. "But more important was finding anything so complex as an apparently photosynthetic organism," Schopf added...
...farther into the past. Last week Dartmouth Professor An drew McNair reported to the Geological Society of America that he had discovered the remains of advanced forms of life 120 million years older than any recognized before. As for simpler, one-celled organisms, Harvard's Elso S. Barghoorn told the society that he has found them to be a billion years older than anyone had previously suspected...
Primeval Presumption. During an electron microscopic examination of samples of ancient, black sedimentary rock from South Africa, Paleontologist Barghoorn uncovered the remains of 3-billion-year-old, rod-shaped organisms so small that 50,000 of them, placed end to end, would measure only an inch. Until his find, the oldest known forms of life were more complex tiny organisms-also identified and photographed by Barghoorn (TIME, March 12)-that existed about 2 billion years ago. With the older specimens, he now believes "we are getting close to an area in time-say within a half-billion years-of possible...
...Barghoorn found the black rock near Barbetorn, South Africa on an expedition last year. He then brought the specimens back to Harvard where he discovered the fossils, 50,000ths of an inch in length, with an electron microscope...
...Barghoorn was assisted in the project by J. William Schopf, a third year graduate student in Biology...
