Book excerpt: Officials and religious scholars in the Gulf states have repeatedly banned the teaching of the theory of evolution because of its association with atheism. But Jorg Matthias Determann argues here that, despite official prohibition, research on biological evolution has flourished, due in large part to the development of academic and professional networks. This book traces these networks through the history of various branches of biology, including botany, conservation research, ornithology and palaeontology. Typical of rentier societies, some of the scientific networks in this region consist of vertical patron-client relationships. For example, those in power who are interested in wildlife conservation have been known to offer patronage to biologists working on desert ecology. However, just as important are the horizontal links between scientists both within the Gulf region and beyond. Given the strengths and importance of these two forms of professional networks, Determann argues that we should look at the Arab world as an area interconnected with global science, and therefore fully integrated into the scientific and technological advances being pioneered worldwide.
