“As the scientists, Semir Zeki and John Paul Romaya, wrote in the study itself, “Hatred against an individual may be seemingly irrational and rooted in remote anthropological instincts. Hate based on race or religion would probably fall under this heading. On the other hand, an individual may trace the hatred to a past injustice and hence find a justifiable source for it. There are no doubt many other ways in which the sentiment can be sub-categorized.”””

“. When we love someone, we shut off the part of our brain that judges – a trait that, we hope, has led to more happiness than sorrow. When we hate someone, we leave the judgment part of our brain a’blazing.”

“Did We Evolve to Hate Each Other?

There’s a theory which holds that hatred evolved so that one group of hunter-gatherers wouldn’t feel so bad about stealing resources from another group of hunter-gatherers. In other words, we hate because hate sometimes keeps us alive. It’s a decent theory, but it makes hatred an extremely recent phenomenon, and one exclusive to humanity.”
