Power laws, predictable evolution, and the limits of life - Chris Kempes...

A
central question in understanding the possibilities for life in the
universe is what fundamental constraints and tradeoffs organize
evolution. In this talk Dr. Kempes will discuss how power-laws in
biology highlight common underlying constraints––often basic physical
laws––across the diversity of life on our planet. He will then describe
how work that we have done shows how these relationships can be derived
and used to predict or interpret a range of phenomena including major
evolutionary tradeoffs and ecological response. Specifically, Dr. Kempes
will focus on energetic limitations in microbial life which allow us to
predict the smallest possible bacteria and several other evolutionary
transitions. Notably, he predicts that the smallest bacteria are limited
by fundamental maintenance metabolism along with general space
requirements. Dr. Kempes will also describe how similar work in vascular
plants can be used to predict ecological structure from resource
constraints and how this provides a range of tools for constraining and
potentially detecting vegetation in a range of exoplanetary
environments.
