One of the basic ones that was covered in my ecology class was mating rituals, at some point the idea that you were a good mate got tied to some random action and therefore creatures who can do that ritual well are more likely to pass on their genetic material
Some examples of this are birds dancing and the pufferfish basically making artwork on the sea floor
