What was human civilization like at point when Americans and Old World inhabitants where one people?

by Ilitarist

American civilizations are very different from European/Asian/African ones in culture and technology. Still there are similarities. I wonder if those similarities are sort of "predetermined" for human civilizations or exist from ancient times when both civilizations where one.

Sorry for the vague question, I hope you get what I'm talking about.

If I'm reading your question correctly, you may want to ask r/askanthropology, as the timeframe you're asking about falls into prehistory. Also take a look at the wiki page for Cultural Universals, basic characteristics which all human cultures seem to share.
