{"product_id":"9780773578166","title":"Rethinking Social Evolution: The Perspective from Middle-Range Societies","description":"The focus of Rousseau's enquiry is \"middle-range\" societies - a vast category between hunter-gatherers and states. Breaking away from traditional analyses of social evolution as a response to ecological constraints, he shows that social systems are maintained and transformed through self-interest and suggests that conflicts about sharing generate social transformations that result in inequality and increasingly encompassing socio-political structures.","brand":"MQUP","offers":[{"title":"Default Title","offer_id":47118639628528,"sku":"9780773578166","price":95.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780773578166_p0.jpg?v=1763662438","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780773578166","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
