Recent chemical analyses of Ediacaran sediments reveal that the deep ocean lacked oxygen before and during that ice age, then became much richer in oxygen and stayed that way after the glaciers melted . That sharp rise in oxygen may have been the catalyst to the evolution of animals, including our ancestors.”

I find it beautiful and amazing that the complexity of life came about as a result of a change in the composition in great oceans. I suppose that is one demonstration that we are the product of our environments. I have always wanted to work on practical computational models of evolution to understand how we came to be but I have also always known that we cannot model the evolution of something without at the same time modelling the environment in which it exists.

In reality, the system boundary is a fuzzy and difficult thing to capture. What do you think of using computational models in the practical and empirical study of evolution?
