自然选择显然介导了许多与学习进化相关的物种特征，包括寿命、幼年期长度、社会组织、认知和运动发育的时间，以及与年龄相关的行为倾向的变化，如活动水平、解决问题的灵活性和寻求新信息的动机。对野生种群的纵向研究可以记录这种行为倾向的变化，提供关于学习策略发展的背景的关键信息，在类似于学习策略发展的环境中。Lomas Barbudal猴子项目提供了白面卷尾猴（Cebus capucinus）的发育数据，这是一种在许多生活史和行为特征上与人类趋同的物种。在这个数据集中，主要集中在觅食行为的学习方面，年轻的卷尾猴总体上更活跃，更好奇和机会主义，更倾向于发明新的调查和觅食相关行为。年轻的个体更经常通过观察其他觅食者（尤其是年长的觅食者）来寻找社会信息。年轻的个体更有创造力，更有趣，更有创造力，更少害怕新事物，在从事采掘觅食时表现出更广泛的行为。虽然成年人通常坚持旧的解决方案，但年轻人在觅食时往往结合最近获得的经验（包括社会和非社会经验）。这篇文章是主题“生活史和学习：童年、照料和老年如何塑造人类和其他动物的认知和文化”的一部分。
Natural selection has evidently mediated many species characteristics relevant to the evolution of learning, including longevity, length of the juvenile period, social organization, timing of cognitive and motor development, and age-related shifts in behavioural propensities such as activity level, flexibility in problem-solving and motivation to seek new information. Longitudinal studies of wild populations can document such changes in behavioural propensities, providing critical information about the contexts in which learning strategies develop, in environments similar to those in which learning strategies evolved. The Lomas Barbudal Monkey Project provides developmental data for the white-faced capuchin,Cebus capucinus, a species that has converged with humans regarding many life-history and behavioural characteristics. In this dataset, focused primarily on learned aspects of foraging behaviour, younger capuchins are more active overall, more curious and opportunistic, and more prone to inventing new investigative and foraging-related behaviours. Younger individuals more often seek social information by watching other foragers (especially older foragers). Younger individuals are more creative, playful and inventive, and less neophobic, exhibiting a wider range of behaviours when engaged in extractive foraging. Whereas adults more often stick with old solutions, younger individuals often incorporate recently acquired experience (both social and asocial) when foraging.This article is part of the theme issue ‘Life history and learning: how childhood, caregiving and old age shape cognition and culture in humans and other animals'.
