What to know about When meat doesn't matter: Female Guinea baboons do not prefer males who are better at acquiring or sharing meat

A study by the German Primate Center indicates that female Guinea baboons do not preferentially choose mates based on their ability to acquire or share meat. The research also documented the first instances of female-initiated prey capture, suggesting females are less dependent on primary males for meat than previously assumed.

What happened

When meat doesn't matter: Female Guinea baboons do not prefer males who are better at acquiring or sharing meat Lisa Lock Scientific Editor Alexander Pol Deputy Editor Meat is a rare and highly prized resource for wild Guinea baboons (Papio papio).

Why it matters

Yet, contrary to long-standing assumptions based on human hunter–gatherer societies, a new study by the German Primate Center—Leibniz-Institute for Primate Research (DPZ) reveals that female Guinea baboons do not preferentially choose males who are more…

Common ground

O'Hearn (DPZ & University of Exeter, U.K.), also shows that female Guinea baboons are less dependent on their primary male for access to meat than previously thought after documenting the first-ever case of female-initiated prey capture.
