Cladists claim that only groups consisting of an ancestor and its descendants are "natural groups". However, if there is a finite number of members of such groups, then there must be an infinite number of such groups, and vice versa, because if the number of both is finite, then at least one such group is a paradox (ie, Russell's paradox).
Cladists thus have to pass the insurmountable barrier between finity and infinity, ie, resolve Russell's paradox, to realize their claim, ie, find the true tree of life. Does anyone dare to bet that they will succeed in a limited time frame?
No, cladistics is actually the worst error we can make, that is, to conflate object with class. It is not only stupid, but as stupid as we can possibly be. It is the opposite to sense, that is, nonsense. It actually marks the beginning of the end for science unless it is clearly dismissed by scientists.
