The Claim
Rhesus monkeys that lack the anatomical and neural capacity for overhand throwing exhibit strong avoidance responses to human overhand throwing motions characterized by rotation, speed, and projectile release, indicating that recognition of the functional threat of throwing can occur without prior performance of the behavior.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Rhesus monkeys that cannot throw respond with avoidance when they see humans throw objects overhead with speed and rotation, showing they recognize the threat of throwing even though they have never thrown themselves.
See the scientific wording
Rhesus monkeys, which lack the anatomical and neural capacity to throw, exhibit strong avoidance responses to human overhand throwing motions involving rotation, speed, and a projectile, indicating they can recognize the functional threat of throwing without having performed it themselves.
When the eyes see a fast, rotating arm motion with an object flying through the air, the brain recognizes this pattern as dangerous and automatically triggers a fear response to avoid being hit.
What the research says
1 studyEven though rhesus monkeys can't throw, they still get scared when they see a human swinging an arm fast with something in it — like they know it could hit them. This means they can tell a dangerous throw from just any arm movement, even without ever doing it themselves.
