What are the advantages of having epithelial tissue line the outer human body as opposed to using cartilage as so many animals do?
Epithelial tissue has sensory nerves; cartilage does not.
Epithelial tissue is very regenerative; cartilage is not.
Epithelial tissue stretches well; cartilage does not.
All of these are advantages.
