This process is iterated until extant population K has been founded.
The phylotype root must have a unique annotation, say A, which lasted until extant phylotype members that are annotated by A. Formally, within a clade with root r, every taxon x sharing the same annotation A as r, and for which A is conserved along the path from r to x, belongs to the phylotype defined by r and A (assuming the MRCA condition is fulfilled).
That story doesn't surface in the extant sources until Plutarch, half a millennium later.
In fact, the Houston Texans weren't even an extant team until 2002.
The TMRCA estimates next suggested very little divergence among Pomatiopsidae (at least among lineages with extant representatives) until around 22 Ma, with high rates of cladogenesis 8 – 2 Ma (Table 4).
Furthermore, the Cuban clade branched off from a Hispaniola lineage at 21 ± 4 Ma, but did not apparently diversify into any extant Calisto until 14 ± 3 Ma, while the last aerial connection between blocks of Hispaniola and Cuba existed until 14 17 Ma.
After this origin, there appears to be a long period without additional speciation (as reflected in extant species) until the crown group origins of each of the four major army ant lineages (Aenictus, Dorylus, Aenictogiton, New World army ants) between 37 and 6 million years ago.
Slavery was legally abolished in Korea in the Gap-o reform of 1894 but remained extant in reality until 1930.
Similarly, the Sonora dog lineage, distributed along the western United States Mexico border until 1994, was monophyletic with extant lineages circumscribed southward in west-central Mexico, southeastern Mexico Chiapass), and Central America.
That partnership is not dissolved until both parties are no longer extant.
For even others I help throughout life will eventually die, until all our actions come to naught, until all our subjective experiences and memories reside in no mind, until no conscious being is left extant within a cold and dying and diminishing universe to remember any experience at all.
