Bilaterian Animal Review
How do we classify bilaterian animals further?
Body Cavity (Coelom)
Embryonic Development (Protostome vs. Deuterostome)
Animals are the most diverse eukaryotic group!
Majority of animal species are insects
Evolutionary success of animals is due to ability to
move, feed, and behave in different ways
Unifying features: multicellular h
Lecture 14: Animal Diversity (Ch 44)
1. Know the evolutionary relationships between Sponges, Cnidarians, and Bilaterians and know
that all organisms except for Sponge
and Respiratory System:
How are gases, nutrients, and wastes
exchanged between an organisms body
and its environment?
I. Simple diffusion
II. Respiratory and circulatory systems
A CONSTANT SUPPLY OF OXYGEN IS

COMPLEX MULTICELLULARITY AROSE SEVERAL TIMES IN EVOLUTION.
Know that bacteria are unicellular or form simple multicellular structures.
Oxygenic photosynthesis made possible the
accumulation of oxygen in Earths atmosphere
and oceans. The primary producers of oxygen as
of 800 million years ago that power the modern
carbon cycle are:
