Concerning the Development of Natural Creatures Through Time

Concerning the Development of Natural Creatures Through Time was the 13th-century AH treatise in which Abdallah ibn-al-Zubayr first explained the evolutionary theory. At its first printing, the treatise incensed theologians of the Jewish, Christian, and Islamic stripes. By the 15th century, the Catholic Church still had an official condemnation of the work on the books, but this was not actively pursued. In fact, Pope Marcellus IX kept a copy in his office, on display for any visitors to see.
