catching up with early life
Most of the history of life on our world is about single cells. Life made up of millions-billions-trillions of cells, (just for one critter!) only arrived in the last 700,000,000 years. Life in its single celled form got here 3,400,000,000 years ago. It took life nearly 3 billion years to learn the trick. Continuing the continuing story of Evolution, we look at the Precambrian, and the first multicellular life seen in the fossil record.
