This page is dedicated to molecular and morphological studies
of invertebrate phylogeny. We specialize in the "Lesser-Known" taxa,
particularly those once collectively known as "aschelminthes". These
lesser-known invertebrates are the key to understanding animal evolution.
Our most current hypothesis of animal evolution has the initial branching
of bilateral animals between protostomes and deuterostomes. The protostomes
are divided into two major groups: Ecdysozoa (molting animals) consists
of Cycloneuralia (sensu Ehlers) + Panarthropoda. Lophotrochozoa
(Spiralia) consists of all the non-molting protostomes. Within Lophotrochozoa
is a group Platyzoa that consists of Platyhelminthes, Gastrotricha,
Rotifera, Gnathostomulida and the new group Micrognathozoa. See below
for publications from the Garey lab concerning animal phylogeny.
