“great-apes-lol-like-human-too”
As per the chapter introductions, visit http://primatology.net/2009/06/08/great-apes-lol-like-human-too/ to read the article “great-apes-lol-like-human-too” I would like you to briefly discuss one thing you found interesting about primates (or a single kind of primate), why you found it to be interesting, AND how it relates to Chapter 6. Since I can’t upload my text via files, I would like to ask for writer’s email address so I can send it. Just read chapter6 is fine.

Discussion
One of the things I found interesting about primates is their ability to express human emotions, notably the laughter. The article, “great-apes-lol-like-human-too” suggests that human emotional expressions like laughter originate from an ancestral non-human primate. This is fascinating! The article features a recent study examining tickle-induced laughter in human infants, chimpanzees, bonobos and gorillas. Ideally, the findings offer intriguing proof that tickling-induced laughter is homologous in great primates and human beings. This indicates a phylogenetic continuity of non-human manifestation of expressions. Another interesting point is that distinctively human laughter attributes like consistently aggressive airflow and predominantly regular, stable voicing relates to attributes of shared ancestors with great primates.
The central significance is that regardless of the substantial differences in the contexts and manners that human beings and other primates laugh, human laughter is grounded on emotions. Laughter has been evolving in every ape lineage from similar acoustic reaction displayed by the last common ancestor of apes and humans. For instance, Chimpanzees tend to mimic the laughter of others even if they do not understand the situation at hand. This is funny because these apes do not just copy the expressions of their social surroundings.
The laughter exhibited by great apes is not a “fake laughter” that is exclusive to human beings. In fact, this laughter played a key role in human evolution. The phenomenon of a laughter induced by others’ laughter appears to be greatly linked to primate evolution. Monkeys and Apes similarly mimic the expression of other apes like play faces and yawning.
From a psychological perspective, these apes seem to use their laughter to strengthen social relations just as human beings. This indicates that great apes used social expressions in a much complex manner than I had thought. As human beings, we use laughter as a vital response to various scenarios. However, it is especially intriguing that chimpanzees appear to use laughter asa unique reaction.
