Evolution clearly has no shortage of controversies. But none of those controversies involve the basic principles of evolution, and all of them operate within a framework where random mutation and selection play a key role in creating diverse species that are related by common descent. It’s clear that the Discovery Institute is trying to introduce controversies that don’t exist, while ignoring those that do. That’s why the academic freedom bills it’s promoting are such dangerous things; while supposedly promoting intellectual analysis, they’re actually an attempt to pave the way for misinformation to enter the scientific classroom.
