Evolutionary Biology: How Did Humans Become so Different?

Explore how life on earth evolved and adapted to possess specific characteristics. Learn about defense mechanisms in the human body: why do we have allergies, why do we cough, is morning sickness really a benefit in pregnancy? How are we able to distinguish between men and women while dressed, and what does that have to do with the saber-toothed tiger? How has the meaning of survival of the fittest changed since Darwin? These and other questions of evolution will be addressed.
