This seems like a simple question that was answered a long time ago. The more I read howe-ver, the less confident I am that we actually know why organisms are the size they are. I have been trying to understand the proximate and ultimate drivers of biological size. Using a se-ries of artificial selection experiments, experimental evolution and comparative analyses, I have been exploring both the causes and consequences of size, mostly using fish, E. coli, and phytoplankton. In this talk, I will argue that many of the more famous models of growth have assumptions that don’t match reality, with calamitous consequences for the management of exploited species. Hopefully, I will show that better understanding of growth and size is es-sential if we are to predict the impacts of human activities on biology.
