Here's why:
* Different musculature: Chimpanzees have different muscle structures than humans. Their muscles are designed for climbing, swinging, and tearing through vegetation, not for ripping off limbs.
* Social behavior: Chimpanzees are highly social creatures. They are not inherently aggressive towards humans, especially if there's no perceived threat. Attacks are usually defensive or related to food competition.
* Lack of tools: Chimpanzees don't use tools like knives or axes to tear limbs off. While they use tools for other purposes, they lack the ability to intentionally and efficiently cause such harm.
However, it's important to remember that chimpanzees are wild animals. They are incredibly strong and can inflict serious injuries with their teeth and claws. It's always wise to respect their space and avoid interactions with them in the wild.
If you're interested in learning more about chimpanzee behavior and their interactions with humans, you can find plenty of resources online and in libraries.
