corded -> primate -> human -> human/? -> unknown -> new species no longer primate or human
That suggestion would invalidate common ancestry. Speciation (due to evolution) is a branching process which results in a nested hierarchy. You can also retract the steps backwards (or could, if you had complete information). You're suggesting that a speciation event can occur that puts the daughter species on a different lineage, an evolutionary impossibility.
If it happens, evolution is falsified.
