Did you know that copper had an effect on primitive life? It could have played a role in some early animals developing respiratory systems!
Mining.com reported, "By analyzing a series of geological records, the scientists were able to prove that the level of copper in the environment increased dramatically at the same time as the first animals started to emerge."
This took place about 700 million years ago. Amazing such an unexpected substance had a huge impact on the development of creatures like sea sponges and jellyfish! It's also incredible to think that oxygen used to be toxic to living creatures.
