Of Leaves, Levels and Nested Hierarchies

-
Zachriel showed up earlier today trying to refute something I said wrt any tree of life not producing a nested hierarchy. Zachriel sed that the leaves form the nested hierarchy and to try to support his case he provided the quote in that thread's OP by Eric Knox.

Unfortunately for Zachriel Knox was talking about multiple levels and the leaves on a tree only occupy one. Perhaps he realized that after he posted it and that is why he ran away.

Also, as I pointed out to Zachriel, with any tree of life organisms occupy the twigs, branches and trunk of the tree. That is the whole point of the tree- to show diverging lines of descent with modification...
