The evidence indicates that the early earth that did not support life in the same fashion it does now. Temperatures, different gases and other physical conditions were much more extreme over greater areas than they are today. Organisms that appeared had to be adapted to those conditions, not today’s conditions. Is there evidence that life had evolved to survive in those conditions?
In this discussion, please present your view of the early conditions on earth that might have affected the traits of organisms living in that environment and how life may have formed. Explain how extremophiles represent examples of those organisms.
