The topic of monozygotic twinning (MT) on which the recent paper by Herranz (Herranz, 2013) focuses is indeed a fascinating one, not only for the embryologist. And, as pointed out by the author, it may on principle also be relevant for ethical discussions in the context of embryo research and stem cell work in humans. Obviously, this is the reason why the paper was published in Zygote, in spite of the fact that it concentrates on history and speculation. When reading through the paper, however, I have ended up disappointed.
