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...

...elusive little bugs are smaller than typical bacteria but are generally bigger than true viruses. Even with an electron microscope they are so difficult to corner and classify that their very name is vague-PPLO (for pleuropneumonia-like organisms). But these days that name keeps popping up in lab reports from all over the world.* The baffling microbes have already been indicted for complicity in causing diseases ranging from puerperal (childbed) fever to the "viral pneumonia" that afflicts so many recruits in boot camps. Now they are even being suspected as a possible cause of cancer...
