RD: I know you're working on a programme about Cambrian and pre-Cambrian fossils, David.

G book, Cambrian company realize that can't do a simple collers business card printing and membership card-making factory.

Thus, the "Cambrian Explosion" is a fairly unheard-of term outside the scientific community.

When I finished the book, I was living up above the Elan valley reservoirs in the Cambrian mountains.

They called it the Cambrian Explosion.

This event is sometimes called the "Cambrian Explosion" , because of the relatively short time over which this diversity of forms appears.
