Problem:
Protostomes and deuterostomes are two major groups of animals that differ in important ways during early development. These differences include how their cells divide (cleavage pattern), how their body cavity (coelom) forms, and what the blastopore (the first opening in the embryo) becomes.
Choose one of these developmental features.
Describe how it works in both protostomes and deuterostomes. Need Assignment Help?
Then, explain how this difference might affect the way animals in each group are structured or how they may have evolved over time.
