(Recorded at TEDxPSU, October 2010 […]
Medical ethicist Harvey Fineberg shows us three paths forward for the ever-evolving human species: to stop evolving completely, to evolve naturally — or to control the next steps of human evolution, using genetic modification, to make ourselves smarter, faster, better.
