The abortion debate has reared its head again, this time over undercover videos of Planned Parenthood officials making controversial statements. While partisans on both sides argue largely from principle, I daresay that the majority of the American public view the subject through a practical lens: if what is being killed is recognizably human, then the procedure should be restricted, if not banned.

Answer, from left to right: zebrafish, chicken, four-striped skink, human, and dog.
