Ok, I'm watching Best Evidence on Discovery. The director of Anthropology at Pennsylvania State University states that bigfoot is not possible because he would have a big brain and big brains require a lot of energy. She states that cold environments or even seasonal environments outside of the tropics don't provide the foods that provide the energy needed to survive.
This is odd coming from an anthologist? She's never heard of Neanderthal who had a Big Brain and lived in cold and seasonal climates.
So, do you believe in bigfoot?
