How did the development of early human societies influence language diversification?

The evolution of language is one of anthropology's most intriguing fields of study, intertwining culture, biology, and history. As early human societies began to form, various cultural and geographic factors contributed to the diversification of languages. Some researchers propose that the social structure, environment, and technological advancements within these early communities played significant roles in driving linguistic complexity and diversity. Considering how disparate hunter-gatherer groups transitioned into more settled agricultural societies, what specific elements of those transitions might have spurred the creation and evolution of distinct languages? Furthermore, how did the interactions between different groups—whether through trade, conflict, or migration—further impact language development and differentiation in these foundational human societies?
