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.

the first historical instance of china engaging in internationalism was during the han dynasty.[1] at the start of the han dynasty, the huns in the north were attacking the frontiers of han and trying to obtain riches. emperor wu of han wanted to gain an alliance with a country called dayuezhi so the two countries could join together and fight against the huns.[2] to obtain this alliance, emperor wu sent zhang qian to the west to establish economic and cultural connections.[2] history records that during the han dynasty there were four primary avenues of contact between china and europe. they included the northern land route, the central land route, the southern sea route, and the far southern sea route.[1] the most famous of these routes is the central land route, or the classical silk road, comprising a network of roads stretching from northwest china to the ports of syria and the black sea, which passed through the oasis of the turkestans and northern persia.[1] the silk road was significant for chinese emperors because it provided dominance over central asia by developing resources and provided new markets for the export of china's most valuable resources.[1]
