These splits reflect evolutionary history as populations diverged and evolved independently. Their presence implies that the cnidarian and bilaterian lineages had already diverged. The lineages subsequently diverged in that order. The rusty-spotted cat possibly genetically diverged from this ancestor between . Extrapolating backwards, Ebolavirus and Marburgvirus probably diverged several thousand years ago. Since then the codebases have diverged significantly. Mitochondrial DNA sequences support the theory that these are recently diverged separate species. However, some diverged into other species. Others find that the okapi lineage diverged earlier, before "Giraffokeryx". Over the course of this period, the dialects diverged successively. The implementations have diverged significantly ever since. Australian culture has diverged significantly since British settlement. Among these, the sponges (Porifera) probably diverged first, representing the oldest animal phylum. However, throughout the generations, the breed has diverged into two groups through selective breeding. Ethiopian Jews having diverged from their coreligionists earlier.
