Abstract：
:Primates are highly social animals. As such, they utilize a large repertoire of social skills to manage their complex and dynamic social environments. In order to acquire complex social skills, primates require an extended learning period. Here 1 perform a comparative analysis using independent contrasts to show that social pressures have favored an extension in the proportion of time primates spend as juveniles.

杂志文章abstract：:From c. 2 Ma (millions of years ago) onwards, hominin brain size and cognition increased in an unprecedented fashion. The exploitation of high-quality food resources, notably from aquatic ecosystems, may have been a facilitator or driver of this phenomenon. The aim of this study is to contribute to the ongoing debate ...
