What? No! The view from _any_ absurdly short slice of geological
time will be parochial.
ah. I thought it was parochial because it was from the perspective of the
Neogene. (whereas the Cambrian, for example, is before the arrival of *any*
sort of vaguely mammalian things)
sort of the anthropogenic view of the universe - we know the universe can
support life because we're here.
I honestly don't know any more whether you're honestly asking
questions because you want to know the answers, or whether you're just
I want to know.

then *why* is it parochial? that's what I don't understand.

But I will answer the question anyway. The good of a cladogram is
that it illustrates a phylogenetic hypothesis.
one could say the same about scientific names. and, like a cladogram, if
the hypothesis is wrong, that doesn't discredit the naming procedure...we
just move the name to the group under which we (in a new hypothesis) think
it belongs to.
