Climate and life: The species that exist and the conditions under which they continue
Assembly theory is a new way of looking at the world where humans exist and how they might have come to be ( Assembly of Life ). It includes not only all the things that exist now, but everything that existed in the past. It proposes a lineage of how things came to be as a series of combinatorial steps based on existing forms, each step leading to greater complexity. Looking at the present, we envision humans as a more complex descendant of primates, which developed from some primitive first mammal, and so on back to the first life form only able to interact with it's environment in a very limited way. Meanwhile, as biological forms evolved over billions of years, the conditions under which their development occurred has altered from some rocky turbulent past to a more verdant world with an oxygen rich atmosphere. The earlier environment offered fewer combinatorial options to an emerging life entity. When the air became more populated with a variety of gases, air breathing life t
