Does animal complexity suggest a Darwinian origin, or is it evidence of intelligent design? On this ID The Future, host Casey Luskin begins a two-part conversation with Dr. Uditha Jayatunga, a medical doctor and consultant in rehabilitation medicine in the UK, about the challenges that biological complexity poses to evolutionary theory. Part 1 of the conversation covers the complexity of cells, the need for the simultaneous origin of complex systems, and some fascinating examples of design and complexity from the animal world.
