In science, explanations are restricted to those that can be inferred from confirmable data—the results obtained through observations and experiments that can be substantiated by other scientists. Anything that can be observed or measured is amenable to scientific investigation. Explanations that cannot be based on empirical evidence are not a part of science. The history of life on earth is a fascinating subject that can be studied through observations made today, and these observations have led to compelling accounts of how organisms have changed over time. The best available evidence suggests that life on earth began more than three and a half billion years ago. For more than two billion years after that, life was housed in the bodies of many kinds of tiny, single-celled organisms, some of which produced the oxygen that now makes up more than a fifth of the earth’s atmosphere. Less than a billion years ago, much more complex organisms appeared.

When later questioned on these results, Hardouin stated that he would reveal the monks’ reasons in a letter to be revealed only after his death.
The executors of his estate were unable to find such a document among his posthumous papers.

Melody Newcomb Advertisement For the past two decades scientists have been trying to unravel a mystery in young girls. Breast development, typical of year-olds a generation ago, is now occurring in more seven-year-olds and, rarely, even in three-year-olds. That precocious development, scientists fear, may increase their risk for cancer or other illnesses later in life.
