Why Eurasia? A probe into the origins of global inequalities

Abstract

The abundance of domesticable mammals in Eurasia facilitated its early transition from hunter–gatherer to agricultural economies, with dramatic consequences for human history. This paper empirically examines the origins of these biogeographical advantages and finds that the extinction of large mammals during the past 100,000 years was a decisive force in the evolution of mammal domestication. In Eurasia’s domestication cradles, humans had sufficient incentives to continually practice herd management as a hunting strategy to prevent the depletion of their vital common resources. These strategies changed some targeted species and made them more receptive to human domination. The absence of these conditions (human incentive and animal receptivity) in other regions resulted in the paucity of domestication. The paper presents the most comprehensive empirical analysis of the origins of animal domestication and the roots of global inequalities to date and unearths a critical channel for the influence of deep history on comparative economic development.
