Arunas L. Radzvilavicius

Postdoctoral Researcher of Evolutionary Biology, University of Pennsylvania

I am an evolutionary theorist at University of Pennsylvania, where I study the origin and early evolution of complex life, and philosophical issues of biological individuality. At the core of my research is the ancient symbiosis between bacteria and archaea that gave rise to mitochondria and modern eukaryotes. My long term goal is to explain why the life on Earth is the way it is and also offer predictions on the possible signatures of extraterrestrial life.
My work has previously appeared in Aeon, Quartz, The Singularity Hub, among others.
