Earlier quoted context omitted.
There's a ton of people that, for some reason, just can't grok that humans have been largely behaviorally and biologically identical for the past 200k years. The average ancient roman plebeian's life would not look dramatically different from ours today, minus technology of course. They worked a day job, ate at thermopoliums (basically fast food), lived in crowded apartment complexes with various forms of slum lords,…
Romans, huh? Many of them were slaves, they believed they could learn the future by looking at the patterns of birds in flight, a Roman's bloodline was very important to the Roman's importance. You can take "behaviorally identical" too far, ideas got better over time, people in the past had bad ideas.
If genuine, I'm puzzled. In the current world we have a tremendous amount of people who hold various superstitious beliefs as well as spend tremendous amount of time on their genealogy. And nepotism never went away. I agree those are "bad ideas", but don't see how they differentiate us from people 5k years ago?
