Macaque

In the Associated Press article “Scientists successfully clone monkeys; are humans up next?” Malcolm Ritter, a science reporter from New York City states that, researchers have successfully cloned two female macaques by using the same methods used to produce Dolly the sheep. This is a huge breakthrough because there has never been a successful clone produced from the primate family, which includes monkeys, apes, and humans. Furthermore, Muming Poo of the Chinese Academy of Sciences in Shanghai…

Spillover is not just a regular book about diseases. In this book, the author, David Quammen, dialogues about a multitude of zoonotic diseases, which are pathogens that can be transmitted from an animal into a human. There are eleven diseases that the author primarily discusses: Hendra, Ebola, Malaria, SARS, Q-fever, Psittacosis, Lyme disease, Herpes B, Nipah and HIV/AIDS. All of these are viruses, with the exceptions of Q-fever, Psittacosis and Lyme disease, which are bacterium. All zoonotic…

brains are larger than chimpanzee brains due to increased and continued brain growth velocity in utero. PET imaging has found similarities between humans and macaque monkeys in the activation of language areas of the brain when listening to species-specific vocalizations. Functional MRI has found differences in the connectivity patterns of macaques and humans; however, the capability of fMRI is limited by its sensitivity to head movement. Diffusion-weighted imaging found that white matter…

experienced the brunt of the deficits with rodents, it is the male offspring who are more drastically affected by prenatal stress. Similar to the mice and rats, while rhesus monkeys experienced detrimental side-effects, macaques that were studied actually made some gains. Female macaques, who as fetuses were prenatally exposed to stress, matured faster than their non-stressed peers (DiPietro, 2000, p.…

response. 8. Among the taupe macaques found in Sri Lanka, how does a female’s status influence her access to food obtained by lower status members of the group? There’s a class system, in which a higher ranked female is able to take anything they’d like from a lower ranked member of the group. In the example of the video, the high born female (Emelda) hadn’t gotten any berries before they were all taken and stored in the cheek pouches of the other taupe macaques. In response to obtain food,…

Famous selfies taken by a curious monkey, named Naruto, have brought great controversy and sparked a debate. David Slater, a nature photographer, was on an island in Indonesia taking photographs, when a curious monkey got his camera and snapped a couple selfies. When the photos became viral and Wikimedia started posting the photo on their website, Slater was furious. Because Slater was losing money from the trip, to all the equipment, he wanted the money that was being produced by the picture.…

The mosquito-borne flavi-virus known as the Zika virus was originally found in the Zika forest of Uganda in 1947. Zika first was found in a febrile rhesus macaque monkey and later identified in Aedes africanus mosquitoes from the same forest. The first three cases of human infection were reported in 1954 in Nigeria. The first of the recurring events in humans arrived from Africa and Asia in past years. However, not until 2007, on Yap Island that a major widespread was conveyed. Zika infections…

Desjardins and Fernald (2010) wanted to discover whether fighting an opponent is similar to fighting a mirror image. These male fish are territorial and tend to engage in fighting when they encounter another size-matched male. Thus, Desjardins and Fernald (2010) measured differences in behavioral, hormonal and brain activity between the different conditions. They also measure the immediate early genes such as the egr-1 and c-fos in four brain regions: dorsomedial telencephalon (amygdala),…

type of brain cell that respond equally when we perform an action and when we witness someone else perform the same action. They were first discovered in the early 1990s, when a team of Italian researchers found individual neurons in the brains of macaque monkeys that fired both when the monkeys grabbed an object and also when the monkeys watched another primate grab the same object. Why do sports fans feel so emotionally invested in the game, reacting almost as if they were part of the game…

study was done using the chart system. The subjects were macaque monkeys. These particular monkeys are favored by researchers because they share the hierarchical social structures as humans and they also can become subjected to coronary-artery disease. An anthropologist, Jay Kaplan (Wake Forest University) studied low and high male macaques in captivity. When new macaques were introduce to the group the hierarchy was changed and the old macaques were forced to fight for their position. The…
