"Wouldn't the chromosome fusion event have to happen in a single individual and therefore be a marker for a "first"?"

The first 'person' to get the fusion would still be interbreeding with those who don't have it. If one thinks the fusion makes a human, then you have a human breeding with animals.

We discussed this before but I recall a conclusive agreement.

Wouldn't the chromosome fusion event have to happen in a single individual and therefore be a marker for a "first"?

If someone claims that an individual is the first to prove a mathematician's conjecture, we are involved in a terminus ad quem. There were presumably others earlier who tried the proof. But the first o a class is understood as a terminus a quo, the first of a continuous sequence of successors. But even here there is a problem with evolution within a population. For one who holds that Adam was the first man, the term is obvious. For one who recognized that Homo erectus slowly transformed into H. neanderthalensis and H. sapiens, and eventually one branch gave rise to H. s. sapiens, it is not clear that there was a first member of any of the species or subspecies.
