The cladistic idea of a single True Tree of Life appears as the ultimate spin of all categories

The cladistic idea of a single True Tree of Life is contradictory by illustrating change, because change is contradictory.

This fact doesn't mean that a single event (like a hypothetical origin of biodiversity from a single primordial form) can't be unambiguous, but that it can't be described unambiguously. The insurmountable barrier resides in fusing one piece of change (ie, one process) with two consecutive pieces of entities (ie, two patterns), and is called Heisenberg's uncertainty principle.

This barrier believed the German entomologist Willi Hennig himself capable of bridging by only acknowledging change (ie, contradiction), thus denying pattern (ie, unambiguity), just as if acknowledgement of only contradiction can TURN contradiction non-contradictory.

Willi Hennig thus believed himself capable of getting rid of Heisenberg's uncertainty principle by only acknowledging contradiction, and thereby turning the principle up-side-down into an opposite certainty principle, although change is just as contradictory (and Heisenberg's uncertainty principle just as real) after this mental exercise as it was before. This belief (today called cladistics) does thus emerge in an extremely tight spin from sensibility to insensibility, appearing as the ultimate spin of all categories.
