When Fruit Is Scarce, These Monkeys Hunt Animals. The Behavior May Offer Clues About the Origins of Humans' Meat-Eating Habits
- On Wednesday, zoologist Noemi Spagnoletti and colleagues published findings in PLOS One showing that bearded capuchins hunt and consume small vertebrates more frequently when fruit is less abundant.
- Spagnoletti analyzed data from a long-term field study in Brazil conducted between 2006 and 2010, where the team logged over 5,000 hours of observations documenting dietary behaviors.
- The team recorded 281 instances of vertebrate predation, noting the monkeys often consumed brains and guts first for fats; those finding their own food hunted 1.9 times as often as fed groups.
- Primatologist Susana Carvalho of Gorongosa National Park suggests "meat may be important to buffer seasonal changes," noting these behaviors model how early hominin diets emerged.
- Biological anthropologist Margaret Bryer of the University of Wisconsin-Madison notes that observing diverse species like capuchins offers new research opportunities to revisit the fossil record and identify potential prey species.

When Fruit Is Scarce, These Monkeys Hunt Animals. The Behavior May Offer Clues About the Origins of Humans' Meat-Eating Habits
The bearded capuchins of northeastern Brazil typically eat plant-based foods, but they turn to small vertebrates when those sources are limited. Our ancestors may have done the same, eventually allowing predatory behaviors to be more frequently passed on in our lineage
Scientists watched wild capuchin monkeys for 45 months and recorded around 280 vertebrate-eating events; when fruit became scarce, the monkeys increasingly turned to lizards, snakes and other animals for food
In Brazil, capuchin monkeys exhibit remarkable adaptability by hunting small animals when fruit supplies dwindle. This shift highlights their versatile omnivorous diet and responsiveness to environmental changes. Interestingly, adult males were observed hunting vertebrates more often than younger females. Furthermore, when alternative food sources were available, the monkeys relied less on hunting, presenting intriguing implications for understa…
Free Food Made These Monkeys Nearly Quit Hunting, What It Says About Humans
Capuchin monkey hunting dropped sharply when researchers provided food, echoing a possible turning point in human evolution. The post Free Food Made These Monkeys Nearly Quit Hunting, What It Says About Humans appeared first on StudyFinds.
(Seoul = Yonhap News) Reporter Lee Joo-young = As the fruit they primarily eat becomes scarce, Brazilian capuchin monkeys hunt more small vertebrates such as lizards and rodents...
