Talk:Knuckle-walking

A fact from Knuckle-walking appeared on Wikipedia's Main Page in the Did you know column on 4 September 2009 (check views). The text of the entry was as follows:

Did you know... that knuckle-walking (pictured) is done not only by chimpanzees, bonobos and gorillas but also giant anteaters and platypuses?

Chalicotherium

Pretty sure Chalicotherium knuckle-walked, too? Can extinct animals be mentioned? It seems very primate-centric right now. 209.136.39.130 (talk) 13:22, 27 October 2016 (UTC)[reply]

Our Chalicotherium article mentions that they were knuckle walkers and this article itself already mentions Chalicothere. Yes, extinct animals can be added, but please ensure you use RS to support any content you add. DrChrissy ^(talk) 16:24, 27 October 2016 (UTC)[reply]

Ardipithecus ramidus

My reading of Science 2 October 2009 special issue on Ar. ramidus is that Ar. radmdus has put an end to the theory that a direct ancestor of hominids was knuckle-walking. Is that right? --Nbauman (talk) 02:20, 6 November 2009 (UTC)[reply]

picture is of fist walking

The article states that gorillas can fist walk as well as knuckle walk. If you look at the picture, the gorilla is making a fist with the hand that is on the ground. This is different from knuckle walking (see for reference [1]). Someone with some specialty in primates should have a look. —Preceding unsigned comment added by 81.213.54.44 (talk) 10:33, 12 October 2010 (UTC)[reply]

A few suggestions regarding detail

1.) Differences in knuckle walking methods in Chimpanzees and Gorillas is discussed, but similarities in practices are not really discussed. For example, it was found that Chimpanzees and Gorillas share similar phalangeal curvature profiles, both dealing with the pressure put on the phalanges when walking. This might be interesting to include, as it goes along with the idea that Chimpanzees and Gorillas originated from a form of fist walking similar to Orangutans (see http://scholarworks.umass.edu/open_access_dissertations/755/)

2.) In the advantages section, not many advantages are discussed of knuckle walking over Chimpanzees’ and Gorillas’ practice of bipedalism at times. The efficiency of knuckle walking over other forms of locomotion should be discussed more, maybe in a more general sense, and then applied to certain species.

3.) A more general section could be added that discusses the anatomical differences and implications of knuckle walking. Chimpanzees and Gorillas practice different forms of knuckle walking, which has different affects on their physiology (which is discussed in this article but could be discussed more in-depth). Does knuckle walking change their center of gravity and weight distribution? Does this have an impact on their limbs and hands? Questions like these could be addressed in this section to give readers a more comprehensive look at what knuckle walking entails.

Go for it, but be careful with "efficiency" - it's a very loaded term that often gets thrown around incorrectly, and should be restricted to pure ratios of energy output/input. HCA (talk) 14:23, 1 October 2014 (UTC)[reply]

Second Paragraph is Unclear

The second paragraph of this article needs to be entirely rewritten, with attention to punctuation and the proper opening and closing of parenthetical phrases. rowley (talk) 20:29, 4 October 2020 (UTC)[reply]

Species of Pan

There are two species of Pan (genus) - one is the common chimpanzee, one is the bonobo (also called the gracile chimpanzee). Both can be referred to by the simple term chimpanzee. Further, if you are going to include both species in the listing, then call out both species of gorillas as well. As such, I'm reverting again. - UtherSRG (talk) 20:15, 27 November 2022 (UTC)[reply]

Sorry to revert you there UtherSRG. My intention was to clarify that sentence as it either seemed to omit bonobos or used ambiguous terminology. I suppose the taxonomically correct term for the Pan genus members would be panins. In my experience "chimpanzee" is most frequently used to refer specifically to Pan troglodytes and names like "gracile chimpanzee" and "pygmy chimpanzee" have fallen out of favor because they are from an era when bonobos were assumed to be a subspecies of Pan troglodytes. I have no qualms with listing both species of gorilla, the difference being that nobody thinks "gorilla" refers to just one species and not the other. gobonobo ⁺ ^c 21:31, 27 November 2022 (UTC)[reply]
