It is widely believed that juvenile male mammals typically engage in higher rates of rough and tumble play (RTP) than do females, in preparation for adult roles involving intense physical competition between males. The consistency of this sex differe... Read More about A systematic review of sex differences in rough and tumble play across non-human mammals.

The role of population size in folk tune complexity (2022)
Journal Article
Street, S., Eerola, T., & Kendal, J. (2022). The role of population size in folk tune complexity. Humanities and Social Sciences Communications, 9, Article 152. https://doi.org/10.1057/s41599-022-01139-y

Demography, particularly population size, plays a key role in cultural complexity. However, the relationship between population size and complexity appears to vary across domains: while studies of technology typically find a positive correlation, the...

Animal communication has long been thought to be subject to pressures and constraints associated with social relationships. However, our understanding of how the nature and quality of social relationships relates to the use and evolution of communica...

Maternal investment, life histories, and the evolution of brain structure in primates (2019)
Journal Article
Powell, L. E., Barton, R. A., & Street, S. E. (2019). Maternal investment, life histories, and the evolution of brain structure in primates. Proceedings of the Royal Society B: Biological Sciences, 286(1911), Article 20191608. https://doi.org/10.1098/rspb.2019.1608

Life history is a robust correlate of relative brain size: larger-brained mammals and birds have slower life histories and longer lifespans than smaller-brained species. The cognitive buffer hypothesis (CBH) proposes an adaptive explanation for this... Read More about Maternal investment, life histories, and the evolution of brain structure in primates.
