But his first public display later this year is at the heart of a growing storm - one pitting scientists against Kenya's powerful and popular evangelical Christian movement. The debate over evolution vs. creationism - once largely confined to the United States - has arrived in a country known as the cradle of mankind.

"I did not evolve from Turkana Boy or anything like it," says Bishop Boniface Adoyo, head of Kenya's 35 evangelical denominations, which he claims have 10 million followers. "These sorts of silly views are killing our faith."

He's calling on his flock to boycott the exhibition and has demanded the museum relegate the fossil collection to a back room - along with some kind of notice saying evolution is not a fact but merely one of a number of theories.

Leakey fears the ideological spat may provoke an attack on the priceless collection, one largely found during the 1920s by his paleontologist parents, Louis and Mary Leakey, who passed their fossil-hunting traditions on to him.

The museum, which attracts around 100,000 visitors a year, is taking no chances.

Turkana Boy will be displayed in a private room, with limited access and behind a glass screen with 24-hour closed-circuit TV. Security guards will be at the entrance.

"There are issues about the security," said Dr. Emma Mbua, the head of paleontology at the museum. "These fossils are irreplaceable and we wouldn't want anything to happen to them."

Much of the scientific establishment says that intelligent design is not a tested scientific theory but a cleverly marketed effort to introduce religious -- especially Christian -- thinking to students. Opponents say that church groups and other interest groups are pursuing political channels instead of first building support through traditional scientific review.

The White House said yesterday that Bush's comments were in keeping with positions dating to his Texas governorship, but aides say they could not recall him addressing the issue before as president. His remarks heartened conservatives who have been asking school boards and legislatures to teach students that there are gaps in evolutionary theory and explain that life's complexity is evidence of a guiding hand.

The tiny fragment of 1,500-year-old papyrus is written in Greek, the original language of the New Testament, and contains a key passage from the Book of Revelation.

Where more conventional versions of the Bible give 666 as the "number of the beast," or the sign of the anti-Christ whose coming is predicted in the book's apocalyptic verses, the older version uses the Greek letters signifying 616.

"This is very early confirmation of that number, earlier than any other text we've found of that passage," Dr. Aitken said. "It's probably about 100 years before any other version."

In retrospect, this magazine's coverage of so-called evolution has been hideously one-sided. For decades, we published articles in every issue that endorsed the ideas of Charles Darwin and his cronies. True, the theory of common descent through natural selection has been called the unifying concept for all of biology and one of the greatest scientific ideas of all time, but that was no excuse to be fanatics about it. Where were the answering articles presenting the powerful case for scientific creationism? Why were we so unwilling to suggest that dinosaurs lived 6,000 years ago or that a cataclysmic flood carved the Grand Canyon? Blame the scientists. They dazzled us with their fancy fossils, their radiocarbon dating and their tens of thousands of peer-reviewed journal articles.

Get ready for a new Scientific American. No more discussions of how science should inform policy. If the government commits blindly to building an anti-ICBM defense system that can't work as promised, that will waste tens of billions of taxpayers' dollars and imperil national security, you won't hear about it from us. If studies suggest that the administration's antipollution measures would actually increase the dangerous particulates that people breathe during the next two decades, that's not our concern. No more discussions of how policies affect science either -- so what if the budget for the National Science Foundation is slashed? This magazine will be dedicated purely to science, fair and balanced science, and not just the science that scientists say is science. And it will start on April Fools' Day.
