>Society and civilization is basically what comes out of setting aside tribalism. Tribalism doesn't mean heterogeneity, it means accepting people outside of your tribe as a potential valuable to you, instead of treating them as default dangerous. Plenty of societies have extremely durable, endogamous tribal identifiers and they got along fine. This is true of India, China, The Ottoman Empire, and so on. India, in particular, has some of the most durable and persistent forms of tribalism around, with castes having remained largely endogamus for centuries or more despite living, working, and trading with each other routinely. Yet this didn't prevent them from alternating with China (itself extremely tribally divided despite the modern attempts to sweep it under the rug and cohere a "Han" nationality) at being the 1st or 2nd most prosperous civilization in the world for most of human history.
