I see just about everything through a biology lens. When I listen to the news about politics or international conflicts, I can’t help but think about how the brain works. I think about past evolutionary pressures that rewarded ancient peoples who cooperated with each other and cared about their fellow humans. And yet, we continue to draw lines and pick sides in arguments that would be hard to explain to an objective third party, such as hypothetical aliens: “I hate an entire group of people because of something that may or may not have happened thousands of years ago.”

So while I definitely don’t want to turn Beatrice into a platform for my political ramblings, I did think about how our predisposition to care about each other may have crossed over into strange territory, and I made a helpful chart to show it. (Click to enlarge if you’re having trouble reading it.)
