Chimpanzees Can Vary Smile Like Human Analysis

511 Words3 Pages

The article I chose to write about is called Chimpanzees Can Vary Smiles like Humans. Humans have long been communicating through facial expressions. Whether happy or sad, a person’s facial expression can tell you a lot about how they are feeling. Our relatives, chimpanzees, have been studied in a variety of ways, because human and chimp DNA varies by just over 1%. A new study published in the journal PLoS ONE, from the University College of London, states that chimpanzees also have the ability to smile like humans when we laugh. Human can smile with or without laughing and talking, and the study concluded that chimpanzees can also smile silently. During the experiment, the scientists saw that chimpanzees were able to produce 14 open mouthed facial expressions. The …show more content…

Although chimpanzees and humans are closely related, specifically 99% of our DNA is the same; humans do not look like chimpanzees. This is because when DNA is being synthesized in a eukaryotic cell, during RNA processing, our junk DNA is cut out. This happens so that the ribosome can’t read the DNA section that codes for making a chimpanzee. However, even though the junk DNA is cut out, it is kept in case humans need to evolve in the future. This is a key part of evolution. I found this article extremely interesting, because I think that evolution is very fascinating. It was also interesting for me to learn that chimpanzees are so closely related to us, to the point that they also share the same ability to smile. Furthermore, it was fascinating to learn that scientists are studying chimpanzees so closely, with the newest technology. I would love to know more about the other animals that humans are closely related to, and how. I think that this would be interesting to know, because humans can study and begin to uncover more and more information about evolution. This information could also help us learn how different species might evolve in the

Ancestors In Our Genome Summary

988 Words | 4 Pages

Ancestors in Our Genome, addresses the continuingly advancing disagreement upon whom our closest ancestor is within the great apes, described as the hominoid trichotomy debate. The author, Eugene E. Harris examines many different sources of evidence within the book, and with the help of improvements in biological and DNA technology he helps discover who our closest ancestors were. Also when we were first separated from them and how the separation took place. Although there have been many recent advances in technology, a large number of unanswered questions are still a mystery within our genome and evolution from the great apes. Chapter one discusses the debate of morphology - studying fossil evidence of the great apes - versus molecular

Bonobos share 98.7% of our genetic make-up (DNA) (Carroll, n.d.). This leads too many similarities between bonobos and humans, but also some key differences. Being so that bonobos share so much DNA makes them closer to us than they are to gorillas (7 Facts about Bonobos n.d.). Bonobos have an upright skeleton, long legs, and narrow shoulders.

Similarities Between Bonobos And Chimpanzees

905 Words | 4 Pages

Humans and apes are almost the same, evolutionarily speaking because of our descendants of common precursor of Bonobos and chimps. While many people claim that chimpanzees provide the most insights into the evolution of human behavior, there's arguably a primate that we resemble even more closely, in several key ways. Humans and apes are almost the same, evolutionarily speaking; they've even given us some of our most important adaptations--our size and height, as well as important skeletal changes. Based on the observable physical, behavioral, and emotional characteristics, as well as the habits and culture of bonobo monkeys, as compared to chimpanzees, bonobos provide a better precursor to human behavior than chimps. Bonobos and Chimpanzees are very similar to human.

Similarities Between Primates And Chimpanzees

However, bonobos only demonstrate this aptitude in captivity after being taught by humans, whereas chimpanzees create and implement tools in the wild. Chimps have been observed sharping sticks to hunt bush-babies, digging for ants, and cracking nuts with rocks, activities never carried out among wild bonobos. Another disparity is the frequency of sexual behavior among bonobos who participate in such acts to relieve stress or tension in contrast to chimps who only engage in sexual acts for purposes of mating (Hanratty, personal

How Can Project Nim Be Used To Study Human Language

703 Words | 3 Pages

Herbert Terrace was testing the hypothesis that if communication was taught to a ‘humanised’ chimp, we would be able to better understand how language is acquired in humans. The object of the experiment was to see whether the chimpanzee, named Nim Chimpsky, could learn human language, specifically American Sign language (ASL). The chimp would be raised within a family and taught human language as a child would. The rationale behind this experiment was extremely popular and thus attracted government and institutional funding.

The more that we study chimpanzees the more fascinating facts we find about their history and their way of communicating and living. Throughout history we have learned that these primates have their own “language” in which they communicate in their community. Also they seem to be a lot of similarities between chimpanzees and humans.

Visual Humor In Deaf Culture

The cues mentioned by the parents were smiling, laughing, and the child looking up at them to gauge their reaction. Hoicka and Nameera (2012) found that children were more likely to laugh and look up at their parents as they were joking than they were to smiling as they watched for their parents’ reaction. However, both of these cues occurred more frequently than when children laughed or smiled without looking at their parents. The data supports the idea that laughter is a more common indicator of the production of humor when compared to smiling.

Although humans and monkeys are different, they are also very similar. They are probably more similar than they are different. Despite their differences, it is often said that humans were once apes, a type of monkey that within the years slowly evolved to adapt to their climate and environment. With this evolution came a lot of changes, especially physical ones. While it is not known if this is true or not, it is true that humans and monkeys are closely related.
