"Gorillas' Chest Beating: Conflict Prevention, Not Provocation, Study Reveals"

Originally Published 1 year ago — by Good News Network

A new study based on years of observation of mountain gorillas reveals that chest beating serves as an honest demonstration of body size, with larger males producing deeper sounds to broadcast their dominance and keep rival males away. The thumping is believed to diffuse fights rather than provoke them, as smaller males use their own chest thumps to alert dominant males of their presence while demonstrating they're no match physically. Additionally, the chest thumps correlate to reproductive success and may influence female behavior, with future studies set to explore their impact on attracting females from other social groups.

Cracking the Code: Decoding Primate Language

Originally Published 2 years ago — by Phys.org

A study conducted by the University of Geneva (UNIGE) reveals that the human brain is capable of identifying the vocalizations of certain primate species, such as chimpanzees and macaques, if they are close to us and if the frequencies used are also close to our own. The study found that both phylogenetic proximity and acoustic proximity play a role in our ability to differentiate between primate vocalizations. The frontal and orbitofrontal regions of the brain are activated when processing these sounds, but the activation is reduced when confronted with bonobo vocalizations due to their high-pitched and distinct frequencies. Further research will focus on identifying the emotional content of primate vocalizations.
