Just a quick post to suggest a fantastic program. I watched this and was mezmorized. The last episode of NOVA (on PBS) was called, “What Darwin Never Knew”. It delved into the genetics that Darwin could never have been aware of, yet reinforced his theories. The program illustrated just how brilliant Darwin’s theories were, considering he had no access to modern genetic research.
