A new study published in the International Journal of Primatology reveals the manual dexterity of chimpanzees
The groups of chimpanzees living in our rehabilitation centre have revealed new evidence about the use of tools and manual dexterity in our closest relatives. By observing how these primates use branches to extract food from artificial termite mounds, researchers have discovered behaviours that could help us better understand the evolution of our own manual skills.
Among the study’s most notable findings, it was discovered that most of the chimpanzees showed a preference for using their right hand, similar to humans. Additionally, they preferred longer tools to reach the food, suggesting that chimpanzees not only choose but also adapt their tools according to the situation. The study also revealed that the chimpanzees use a variety of one-handed grips, demonstrating surprising flexibility in their manipulation skills.
Why is this relevant?
This type of research not only helps improve the welfare of animals in captivity by providing them with stimuli that mimic their natural environment, but also sheds light on how our primate ancestors developed the first simple technologies. Chimpanzees share over 98% of their DNA with humans and a better understanding of their skills could help unravel the evolution of our own cognitive and motor abilities.
