Chimpanzee females employ copulation calls strategically to minimize social competition, particularly with other females. This behavioral adaptation allows them to secure the protective support of high-ranking males, thereby reducing risks associated with female-female competition.
A recent study found that maternal grandparents were more likely to maintain daily or weekly contact with their grandchildren than paternal grandparents. The research suggests psychological mechanisms rooted in evolutionary history, where women are always related by maternity, making family ties through the mother more significant.

The study reveals that 1- and 3-year-old children, as well as great apes, prefer a place-based strategy to remember hidden items, while humans reassess this preference with age. This suggests that some evolved cognitive strategies are masked early on in human development.

Babytalk plays a crucial role in infants' development of temporal arts, such as literature and music. Depriving babies of poetic elements like alliteration and assonance may hinder their ability to appreciate these arts later on. Researchers argue that babytalk is more significant than previously thought.
