This chert, formed in volcanic hot springs, preserved several species of early plants in cellular detail by petrification.
We might have even less time if we don't start making improvements. New type of Green Algae produced O2, which created the Ozone Layer that protected life from damaging UV Rays and gave life a chance to progress.
(1.5 Billion Years since the Birth of Earth) - 2.4 billion years ago, oxygen in the atmosphere suddenly increased by about 10,000 times in just 200 million years.
Protein Domain is a conserved part of a given protein sequence and (tertiary) structure that can evolve, function, and exist independently of the rest of the protein chain. Prior to the Cambrian explosion, most organisms were simple, composed of individual cells occasionally organized into colonies.
Over the following 70 to 80 million years, the rate of diversification accelerated by an order of magnitude and the diversity of life began to resemble that of today.
