Biology and political orientation have to do with the way people think about things. Our biology is the things that make up our body, like the cells and organs. Political orientation is the way people think about politics. For example, some people like the idea of having one leader rule over everything, while other people think it is important for everyone to have a voice in how their community is run. The way people think about these things is affected by the biology of their body. For example, scientists have studied how certain hormones, which are chemicals that our bodies make, can influence how we think about political ideas.
