Abstract: The evolution of eukaryotic (nucleus-containing) cells such as our own from simpler life forms is a puzzle that has challenged biologists for more than a century. The prokaryote-eukaryote cellular divide is enormous and many fundamental questions about the origin of eukaryotes and their symbiotically derived mitochondria and plastids (chloroplasts) remain unanswered. Comparative genomics is a powerful tool with which to address such questions. In this lecture I will place the modern-day study of cellular evolution in a historical context, highlighting advances and lingering uncertainties in our understanding of the role of symbiosis in the evolution of eukaryotic organelles.
