Michio Kaku: How can we predict success in humans?

- The brain evolved in three parts, from back to front: First, the so-called reptilian brain or spatial brain; then the monkey or social brain; and the most recently evolved section is the frontal lobe, which understands time. - What's so special about this temporal ability? It allows humans to forecast into the future—to consciously plan, dream and strategize. That's a unique trait in the animal kingdom. - Physicist Michio Kaku believes this trait may also define success among our species, as evidenced by the global correlation in the marshmallow test: Those who wait for the second marshmallow tend to be more successful in life. Listen to Kaku explain why that ability to look ahead and not take shortcuts may be an important predictor of success. Dr. Michio Kaku is the co-founder of string field theory, and is one of the most widely recognized scientists in the world today. He has written 4 New York Times Best Sellers, is the science correspondent for CBS This Morning and has hosted numerous science specials for BBC-TV, the Discovery/Science Channel. His radio show broadcasts to 100 radio stations every week. Dr. Kaku holds the Henry Semat Chair and Professorship in theoretical physics at the City College of New York (CUNY), where he has taught for over 25 years. He has also been a visiting professor at the Institute for Advanced Study at Princeton, as well as New York University (NYU).
