Braden Allenby, an engineer and ethicist at Arizona State University and Conor Walsh, a biomedical engineer at Harvard and founder of the Harvard Biodesign Lab, discuss what our bodies might look like in the future. What does it mean to be human when we can use new tools to alter our phenotype? Is the use of engineering to change the human form new or are we simply using new methods to satisfy an evolutionary desire for change? With explosive animation by the animation team at Moth Studio, and sound by Skillbard.
