Evolution is a theory that is almost self-evident. I hope that the pupils in these classrooms can determine the truth for themselves.
I wish that were the case. To give one example, housecats are so vastly different than monkeys that initial observation wouldn't necessarily point toward a single primitive mammal ancestor. The theory of evolution gets so expansive when you consider billions of years that it's easier to believe in intelligent design.
In a clever twist, many creationists have started claiming that they accept micro-evolution (e.g. the idea that bird beaks would change over generations like Darwin observed) while denying that macro-evolution happens. Thus they can account for the high-school-science-class information that most people get while still clinging to creationism as the overarching truth.
