  Because Insectivora includes tenrecs, which are
being excluded, as well as a group of other forms, and
presently may be considered polyphyletic in consisting
of a series of forms, some of which (eg.,
macroscelids) are considered closer to archontans
(including bats and primates), or afrotheres (this
would be called Uranotheria). I also am not aware of a
phylogenetic definition for Insectivora, but the group
my be historically a polyphyletic assemblage. The only
apparent insectivores still considered in that same
"region" of the phylogeny would be talpids (moles) and
the like, as well as shrews.

  Insectivora could be considered a polyphyletic taxon
that represents a grade, not a natural unity
(primitive eutherians).

  Dinosaurs are horrible, terrible creatures! Even the

  they're fun and sweet, but watch out for that stray tail
  spike! Down, gaston, down, boy! No, not on top of Momma!
