Article: During most of the Neolithic age of Eurasia, people lived in small tribes composed of multiple bands or lineages. There is little scientific evidence of developed social stratification in most Neolithic societies; social stratification is more associated with the later Bronze Age. Although some late Eurasian Neolithic societies formed complex stratified chiefdoms or even states, states evolved in Eurasia only with the rise of metallurgy, and most Neolithic societies on the whole were relatively simple and egalitarian. Beyond Eurasia, however, states were formed during the local Neolithic in three areas, namely in the Preceramic Andes with the Norte Chico Civilization, Formative Mesoamerica and Ancient Hawaii. However, most Neolithic societies were noticeably more hierarchical than the Paleolithic cultures that preceded them and hunter-gatherer cultures in general.

Question: What cultural trend did not first appear in large amounts until the Bronze Age?
Ans: social stratification
