P. Z. Myers points to a video of a dog running through traffic to try to save another dog that had been hit. He says:
Keep this in mind when you encounter people yeah, I'm looking at you, Francis Collins try to argue that morality and altruism and empathy are unique markers of a divine hand in our origin.
Greg Mayer adds:
[W]e’ve long known that dogs have rudimentary moral sentiments, and Darwin included observations of his dogs (the second of which was named Bob) in his writings on the subject (see here, especially chap. 3, and here both links are to The Complete Works of Charles Darwin Online). A sample (Descent, vol. 1, p. 77):
I have myself seen a dog, who never passed a great friend of his, a cat which lay sick in a basket, with-out giving her a few licks with his tongue, the surest sign of kind feeling in a dog.
PZ needs to chill out. Saint Francis knew this a long time ago. There is a divine marker in all living creatures.
