16: Development and Architecture of Animal Body Plans ... In this lab will explore some of the basic features of animal embryology, and introduce some ways that changes in body plans depend on simple differences in patterns of early development.

ANIMAL BODY PLANS: HOMEOBOX GENES; How a single fertilized cell develops into a complex organism like a fly, a mouse, or a human being has long been one of biology's greatest mysteries. Now the molecular revolution that revealed the double helix has taken on the conundrum of animal development as well.

The simplest organization (seen in the flatworms) is the acoelomate body plan. In these animals the body cavity is loosely filled with mesodermal cells called parenchyme. ... The peritoneum surrounds all organs in the body cavity. In some coelomates the coelom may be present only in larval stages or may be greatly reduced.

But the rocks exposed in those far-flung areas hold the oldest record of animal life, a prelude to the evolutionary explosion of animal body plans that was to come.

This happens as their body plans are being laid down. It seems that an efficient way of marking out the body plan arose millions of years ago, and has remained virtually unchanged throughout animal evolution...
