But as we discover more and more about our intelligent and playful cousins in the animal kingdom, it is worth reflecting on the astounding number of characteristics we share rather than the differences that separate us. There are of course many differences between the humans and chimpanzees -we stand on two legs, have larger brains and are relatively hairless. Chimpanzees not only communicate like humans, they also demonstrate a range of emotions including joy, sadness, fear and even empathy. In doing so, they make themselves look as big and dangerous as they possibly can and indeed may eventually intimidate a higher-ranking individual without having to fight.ġ. Male chimpanzees proclaim their dominance with spectacular charging displays during which they slap their hands, stamp with their feet, drag branches as they run, or hurl rocks. When angry, chimpanzees may stand upright, swagger, wave their arms, throw branches or rocks-all with bristling hair and screaming or with lips bunched in ferocious scowls.Ģ.

The grin of fear seen in frightened chimpanzees may be similar to the nervous smiles given by humans when tense or in stressful situations.ģ. For this reason, social grooming is one of the most important social behaviours, serving to sustain or improve friendships within the community and to calm nervous or tense individuals.Ĥ. They say wild chimps communicate 19 specific messages to one. S.5. Friendly physical contact is crucial in maintaining good relationships among chimpanzees. Researchers say they have translated the meaning of gestures that wild chimpanzees use to communicate. That’s all for today, hope somebody finds this interesting, C. Our, among simians, unique foot with five toes in a row is not so much for walking as for fast and/or long-distance running. Gorilla’s walk on their knuckles, Orang-Utans on their fists, they are very heavy.Ĭhimpanzees walk on their knuckles, they can’t stretch their knees.īonobo’s walk about evenly on two and on four ‘legs’.īut all apes, all monkeys, can and do walk on two legs. Gibbons (the ‘lesser apes’, but still apes) walk on two legs, they have proportionally the longest arms. Humans walk on two legs, our arms are short. Now they/we can’t walk on the palm of the hand anymore, but no problem, hanging from a tree branch the head and legs are already in the right position to walk upright. Their/our wrists stiffened thanks to a mutation that stayed because it’s handy for catching branches while flying.

We don’t really know why, but she tends to stand and walk bipedally more often than not when she’s in the grass on Young’s Hill, even when her hands aren’t full and she’s not trying to spy on something at a distance.Īpes are one of the few simian species that swing under branches instead of walking over them. While chimpanzees are mainly quadrupedal when walking and standing (of course they can also swing through the trees), there are times when they stand up on their feet and sometimes walk bipedally like us humans.Īt the sanctuary, a frequent reason to stand up is to spy on the neighbors or spot something at a distance:Īnother pretty practical reason to walk bipedally is when your hands or arms are really full:īeing short myself, maybe I’m projecting this on to Missy, but I think I stand up straighter and raise up on my tip toes a lot more than less vertically-challenged people, so I equate this to Missy standing up just to be taller once in a while:Īnnie, however, is somewhat of an exception.

One cool thing about knuckle-walking is that it leaves your hands free to carry your dolls: Chimpanzees have long arms with long-fingered hands and they bend their fingers underneath, walking on the knuckles of their hands and the flat part of their feet. They not only share our handy (pun intended) opposable thumbs, but they have “thumbs” (technically referred to opposable toes) on their feet too.Īnimals with four legs generally have limbs that are pretty much equal in length and they walk on the same part of each of their feet.

Like humans, they have two legs and two arms. Chimpanzees are considered quadrupedal (walking on four limbs), but they don’t have four legs like many other mammal species.
