While researching Dependent Origination I stumbled across an interesting
article/paper by Eisel Mazard:
Discarding Dependent Origination, Returning to the Primary Source of the
12-Links in Theravada Buddhism, 2011.

"My conclusion is, simply, that the 12-links formula is unambiguously an ancient tract that was originally written on the subject of the conception and development of the embryo, as a sequence of stages prior to birth; in examining the primary source text, this is as blatant today as it was over two thousand years ago, despite some very interesting misinterpretations that have arisen in the centuries in-between."
