Harun Yahya (Adnan Oktar) is the head of the largest creationist organization in Turkey, and perhaps in the whole Islamic world. His activities and influence is also felt internationally. He distributed tens of thousands of copies of his book, “The Atlas of Creation” to many prominent researchers and research institutes throughout the United States and Europe. He also carried out a campaign placing ads on the busses in London.
But his main influence is felt in the Islamic world, especially in Turkey. And it is not only his creationist propaganda that causes the problem, but he and his followers have also been running campaigns to intimidate and suppress evolutionists and evolutionism in Turkey.
In the recent years, he has been responsible for filing lawsuits that banned thousands of websites that had non-religious, evolutionist or atheist content in Turkey, including Richard Dawkins’ website, wordpress domain, google groups and many others.
