Why does neoevolutionism focus on differences and interactions among societies?

Neoevolutionism focuses on the differences and interactions among societies because it rejects the 19th-century assumption that all cultures follow a single, predetermined, or inevitable path of development. Instead, this school of thought emphasizes that social evolution is a patterned and cumulative process that occurs through probabilities rather than fixed stages.1

By examining variations between societies, neoevolutionists seek to understand how specific groups adapt to their unique environments through localized social and ecological adjustments. This focus allows researchers to investigate:2

• Environmental Adaptation: How different cultures adapt to similar or unique environments to survive and thrive.2
• Acculturation: The study of the relations of influence among societies, recognizing that cultures do not develop in isolation but are shaped by their interactions with one another.1
• Historical Trajectories: The similarities and differences in the long-term development of unrelated groups.2

Ultimately, this approach provides a more nuanced understanding of social change by prioritizing empirical observation of how diverse societies navigate their specific historical and ecological contexts.21
