And yet, we still fight for the most common goods and territory.

Humanity/mankind do not even need a real reason to start a fight/war. They can start a fight/war even because of religions.

So what have we learned from it, evolution?

Probably very little, which is very sad. I just/only hope that the current Ukrainian-Russian conflict/war will not turn into the third world war.

Have a nice day and have a nice weekend.
All the best. Greetings and much love from Hungary.
