In real life, Harun Yahya is a 51-year-old former interior-design student named Adnan Oktar. Since founding the BAV in 1990, Mr. Oktar has been responsible for ushering more than 250 books into print, though many observers agree he serves more as the chief overseer of a group of writers rather than as a solo author. The series includes titles such as "The Dark Spell of Darwinism" and "Why Darwinism is Incompatible with the Koran."

Oktar's brand of creationism is not only religious, but also political and even messianic, seeing most of the world's ills – terrorism and fascism among them – as stemming from Darwin's theory of evolution.

"Hitler, Mao, and Lenin were Darwinists. At the root of wild capitalism is also Darwinism. I think if we no longer believe in Darwinism, people will no longer be conditioned to believe in those things," the normally reclusive Oktar said during a recent press conference, held aboard a hired yacht cruising Istanbul's Bosphorus strait.

"Folks, there is no such thing as what you call evolution. If there was, it would be in the Holy Bible or the Koran," added Oktar, dressed in an ivory-white raw silk suit and wearing gold cufflinks and a matching gold belt buckle with Arabic inscriptions on them.

"The sweet dream of the Darwinists and the world is to ban my books," Oktar said, sipping glass after glass of sour cherry juice. "What I'm saying is true. They cannot disprove it."

Unlike fundamentalist Christian creationists, Oktar does not claim the earth was created only a few thousand years ago. Instead, he argues that fossils show that creatures from millions of years ago looked just like the creatures of today, thus disproving evolution
