I have missed the beginning of this discussion, but where is the
documentation that breastfed babies have "tighter anuses?"

From an anthropological standpoint, I find this hard to believe, and believe
that there would be no data on this, though I could be wrong.

I think we need to think over how long humans have been breastfed and in
their present form, from an evolutionary standpoint, and then compare that
to the total time humans have been "formula" fed as a group, and then we can
see that the later is a pindot, and the former group, that of normal, bf
babies, has been happening for thousands of years.....

Just having listened to Jim McKenna, me thinks that this premise is
incorrect re: tight anal openings.

Correct me if I'm wrong, Dr. Dettwyler.
