The problem occurs when one tries to find a morph type of a ancestor parent (or transitional form if one was assuming it was fair to speak of species no matter how fancy the conversation got)(there is such a notion of "return to the parent form" which is somewhat similar between Darwin and Wallace but do not ask for the citation i have that not here now).
I had thought about this before I began to read Pascal and became acutally even more confused than the time it took me too realize some of the language barrier which I find is usually 75% of the reason I do not understand something in biology and having absoutley nothing in that probability to do with the facts as they are/were etc...when the concept of this process in plants is connecting to the OPEN HABITAT (when I was trying to track with morphology fern forms and chromosomoe numbers AND geographic locations) because this notion menat that the split splits space from the perspective of the aninmal unless .... up to date , a third division that Pascal could not think of in communicating with Fermat that facial as well as a dice and stake division exists even if this is a corruption of the history of infinite divisibility that Cantor tried to purely clear in the Mess of greek I may have done to translation of Anaxagoras when they come out.
