Life on Earth: By Chance or By Law?
Brian J. Enquist, Professor, Ecology and Evolutionary Biology
Life on Earth is amazing and multifaceted. Ultimately all of life has descended from one common ancestor and has been guided by evolution by natural selection. On the one hand, the evolution of modern-day diversity and ecosystems may have been contingent on the initial chemical building blocks of life and the historical events that have characterized our planet over geologic time. On the other hand, there are numerous aspects of life pointing to regular and deterministic processes that shape the complexity and diversity of life. This talk will touch on those examples where the laws of chemistry and physics, in addition to evolutionary rules, have resulted in general properties of life. These properties ultimately determine how long we live, the diversity of life, the function and regulation of ecosystems and the biosphere, and how life will respond to climate change.
