Students in Turkey are returning to school where they will be taught evolution for the last time in their biology classes. Next fall, evolution and Charles Darwin will be scrapped from their textbooks.

Turkey has announced an overhaul of more than 170 topics in the country’s school curriculum, including removing all direct references to evolution from biology classes.

Education Minister Ismet Yilmaz said the new “value-based” curriculum would teach evolutionary mechanisms such as natural selection but evolution itself was too advanced for high school and would not be taught until college.

The upcoming changes have caused an uproar, with critics calling them a reshaping of education along the conservative, Islam-oriented government’s line. Some biologists say the move will leave Turkish students unable to understand even basic science.
