Exploration is essential for skill acquisition and strongly facilitates cognitive performance. In humans, it is widely known that exploration and later cognitive performance are highly dependent on early social inputs. Here, we aim to shed light on the evolutionary roots of this process by studying the effects of variation in opportunities for social learning on the exploratory tendency of immature orangutans (Pongo spp.) in nature. We based our analyses on mixed cross-sectional, longitudinal data of exploration by immatures and their mothers. Current exploration rates were correlated with levels of past experienced sociability, but not with current food abundance or with maternal condition, and only partly with genetic similarity. We conclude that the dependence of cognitive development on socially triggered exploration, which underlies the construction of cognitive skills such as intelligence, existed before the emergence of the human lineage.

早期的社交能力促进了野生未成熟猩猩的后期探索性趋势。

探索对于技能的获取至关重要，并且极大地促进了认知能力。在人类中，众所周知的是，探索和以后的认知表现高度依赖早期的社会投入。在这里，我们旨在通过研究社会学习机会的变化对自然中未成熟猩猩（Pongo spp。）探索趋势的影响来阐明这一过程的进化根源。我们基于未成熟动物及其母亲的混合横断面纵向数据进行分析。当前的勘探率与过去经历的社交水平相关，但与当前的食物丰度或产妇状况无关，仅与遗传相似性有关。我们得出结论，认知发展对社会触发探索的依赖，
