Can quantum mechanics explain the greatest mysteries in biology? Physicist Jim Al-Khalili turns his attention to the world of nature for answers.

Professor Jim Al-Khalili reveals how Einstein thought he'd found a fatal flaw in quantum physics that implies that subatomic particles can communicate faster than light. The host of "The Amazing World of Gravity" and "Everything and Nothing" shows how robins navigate using quantum entanglement, how our sense of smell is touched by quantum vibrations, and how physics might play a role in evolution.
