All living things possess the element carbon within them. In light of this, Earth had to have a rich supply of carbon to support a rich diversity of life. This carbon was made available by the volatile nature of the Earth in the beginning, where volcanoes spewed various elements into the Earth’s atmosphere.
While other elements were present, various chemical reactions began to take place which would result in the creation of new compounds and elements. One of the family of compounds created over time were the amino acids, the building blocks of protein.
