What trends/characteristics of humanity changed over time and which ones stayed the same

(A quote from an anonymous says : “Over time things change, but some things always stay the same.” From the Era of Foragers, to our Modern Era, our ability to

communicate, organize, create, and destroy have in many ways been altered and also stayed the same. From history we all can now look back and actually see how much things have already been altered, and we can also notice how many things have also remained the same. Some things that will probably always be the same are our race’s ability to be technologically creative. We have an imagination that will virtually never run out, and allows us to always think of new things to change, make, or get rid of to make our lives more convenient. However things that we’re creating or things that we’ve already created are always going to change the way we live.
