As I understand it, they (spiny anteaters, echindas, and platypuses) don't
have a special gland in one spot on their bodies such as a mammary gland, but
rather they "sweat" a milk-like equivalent out of tiny gland spread all over
their bodies like pores (which the babies lap up rather than nurse).
No breasts=not a mammal
Now how would you prove therapsids did it one way or another?
