Hello, buddhaboy,
It really helps to make sure which definition of "evolve" you are using.
One definition of evolve is "slow change over time".
In this sense, rivers evolve, mountains evolve, human cultures evolve.
The definition we are concerned with in this thread is for biological evolution:
Biological evolution is
(1) the slow accumulation of changes to an animal species, caused by the accumulation of genetic changes to the DNA of that species;
(2) the mechanism whereby these genetic changes get made.
The Mechanism of Biological evolution is dominated by several natural processes, including: genetic mutations, sexual mixing of DNA during procreation, natural selection of certain individuals as more "fit" than others, sexual selection of certain mates as more "attractive" than others, and the presence of natural "forces" that tend to kill individuals before they are able to mate and pass on their DNA; such things as predators, climate, competetive species, disease, parasites, geography, etc.
As to the "internal nature" of humans, I think you are referring to violence, greed, loyalty, cooperation, etc. Right?
Well, biological evolution has a lot to do with how we behave, but Culture plays an even bigger role. You and I are probably just as violent as, say, Genghis Khan or Attila the Hun. But we don't act out our violence because we grew up in more peaceful and law-abiding cultures.
Yes, Cultures change over time. But that's not
biological evolution. That's something else. We could call it cultural evolution, and it would have a totally different Mechanism.
