实践和伦理的限制限制了我们在野生灵长类动物中实验测试社会生态学理论的能力。我们采取了另一种方法来模拟这一点，允许人类群体在虚拟世界中互动，他们必须在其中寻找食物并与内组和外组化身互动以获得奖励。我们改变了高价值和低价值食物的比例和分布，以检验这一假设，即原始人的社会凝聚力和群体间的宽容，由于他们的喂养生态。我们发现更大的筑巢集群和减少攻击外群竞争对手的倭黑猩猩条件与黑猩猩的条件，这表明一个显着的影响，喂养竞争的社会结构。我们还表明，虚拟世界是一个强大的机制，用于测试假设，是不可能在野外研究。
Practical and ethical constraints limit our ability to experimentally test socioecological theory in wild primates. We took an alternate approach to model this, allowing groups of humans to interact in a virtual world in which they had to find food and interact with both ingroup and outgroup avatars to earn rewards. We altered ratios and distributions of high- and low-value foods to test the hypothesis that hominoids vary with regards to social cohesion and intergroup tolerance due to their feeding ecology. We found larger nesting clusters and decreased attacks on outgroup competitors in the Bonobo condition versus the Chimpanzee condition, suggesting a significant effect of feeding competition alone on social structure. We also demonstrate that virtual worlds are a robust mechanism for testing hypotheses that are impossible to study in the wild.
