Inverts compromise 99% of all animals on Earth and are remarkably
diverse.  With this almost incomprehensible diversity as a backdrop,
we will consider how invertebrates have managed to solve life's major
problems, organized around a few simple themes and guided by
evolution, ecology, and comparativeanatomy/physiology.  We will also
survey diversity of major invertebrate groups.  Student may take
lecture (Z374) without taking lab (Z375).
