'Darwin, speaking about emotions, made it very clear that animals need emotions to survive. So do we. They need fear as a trigger to escape predators, and aggression to defend their territory, their young, and food.
Emotions– He believed that emotions are really maintained from our animal past in the trajectory of evolution of human animals. And that we really rely on different emotions in different ways to make quick, often complex, decisions.'
