A site whose teaser URL derives less from the philosophical question that humans have asked about their existence for ages, than from Erwin Schrodinger's 1944 tome that formed the framework for investigating molecules as the basis of biology, What is Life takes a conceptual view of living things. It affords visitors the ability to explore topics ranging from our evolving concept of a gene to man, machine, and artificial life. If you're looking for links between biology and art, or you don't understand evolution and wonder what it's all about, What is Life may be the site for you.
