In June 1999, the school district in Burlington, Washington, approved a local science teacher's proposal to use extracts from "Of Pandas and People" in the classroom "so long as he balances it with enough support for teachings on evolution which he always included in his courses but about which he says he has doubts – especially in terms of the origin of the human race". The decision followed an earlier demand by the American Civil Liberties Union, that the teacher, Roger DeHart, should cease his years-long practice of teaching intelligent design in his classes. He stated that he needed to counterbalance the inclusion of information that was "at best wrong and at worst fraudulent" in the standard textbooks used in Burlington schools.
