Geochemistry Interview Question:

Tell me what is the Cambrian?

Submitted by: Muhammad

This refers to the Cambrian period, a geological time, at around 570 – 510 million years ago. It is when invertebrate life first appeared.
During the period comes what is known as the Cambrian Explosion – where the fossil record suddenly seems to radiate with an array of multi-celled creatures.
