Primate

Modern day primates like the Howler Monkey closely resemble the ancient Aegyptopithecus primate. Howler Monkeys known for their loud howls that can reach up to three miles away plus enjoy making nests to live in while Aegyptopithecus are known for bridging the gap between the Eocene and Miocene fossils. The Aegyptopithecus and the Howler Monkey have numerous similarities and differences. The differences include geographic location, skeletal features, and daily behavior; meanwhile similarities…

understanding for what is right and wrong, as well as view models for emotion. Particularly in primate groups the social interactions between members of the communities are based on their rank as dominant or subordinate. In one experiment researchers McFarland, Roebuck, Yan, Majolo, Li, and Guo (2013) discovered that primates had a sense of self respect and respect for others in their community. The primates studied were willing to sacrifice a reward just to view the face of the dominant male…

But can you make assumptions as big as facts if you have no evidence from the time when these events actually occurred? Apes Let’s begin with the facts that we do know. Apes also known by their scientific name Hominoidea are a branch of Old World primates native to Southeast Asia and Africa. They are the sister group of the Old World monkeys; forming the catarrhine clade. There aren’t many things that distinguished the splitting of a clade into two sister clades. The biggest reason…

the life of a squirrel monkey along with the other various primates. Squirrel monkeys are diversified in many countries in Central and South America. There are large quantities of them out there living. Therefore, I will discuss the conservation status, total in the wild, physical characteristics, and behaviors of the squirrel monkeys in the tropical forest. Squirrel monkeys are small creatures that are not a big threat to other primates living in the tropical forest. Squirrel monkeys are shy,…

bipedalism is such a key evolutionary innovation. Few characteristics of being human have engrossed such intense debate than the fact that, distinct from many other living mammals, humans walk upright on two legs. Unlike the quadrupedal primates, bipedal primates are sluggish, clumsy, and particularly unbalanced and disposed to to falls and injury. In spite of the negatives characteristics, bipedalism has allowed humans to multiply to a world population of over six billion. Bipedalism allows…

The last primate I went to see is the Gorilla as knowns as (Gorilla Gorilla). I saw two gorilla at Como Zoo. Gorillas are the largest member of the primate family. They usually eat fruits, leaves, seeds, and insects. Adult males usually have silver-colored hair across the back and hips. The term “silverback” has two meaning, it helps us understand if the gorilla is a male and female and it helps others to see who is dominate. I couldn’t tell if the gorilla was young or old, but I determined it…

traits specific to primates first (things like prehensile hands/feet, the structure of our shoulder and hips, our relative brain size, the presence of at least one fingernail, etc.) and then assess the differences further to classify species from the order of primates. One way we learned to distinguish was by looking at the skulls of different primates. In class we examined several primate skulls, looking at what was similar and what was different among the different species of primates. We…

An example of primates who show a high level of complexity in linguistics are the East African Vervet monkeys. East African Vervet monkeys have been found to use complex vocal sounds for warning others in their group of predators (Zuberbuhler 2005:2). They can only think about feeding themselves and to run from predators to survive and they use various vocal acoustics and physiological movements in order to communicate danger (Zuberbuhler 2005:3). Scientists believe these studies may lead us…

Ebola virus disease EVD or “Ebola” is a severe human and non-human primate disease caused by Ebola viruses. These viruses belongs to the family: Filoviridae, Genus: Ebolavirus, Species: Tai forest ebolavirus (TAFV), Reston ebolavirus (RESTV), Sudan ebolavirus (SUDV), Zaire ebolavirus (EBOV) and Bundibugy ebolavirus (BOBV) (Bukreyev et al., 2014). Zaire ebolavirus or simply Ebola virus (EBOV) is the most virulent of the genus and accounts for the highest numbers of outbreaks. The virus spreads by…

Caitlin: Tues 9 am Scientific Paper Analysis #3: Physiological and Behavioral Response to Weaning Conflict in Free-Ranging Primate Infants Tara M. Mandalaywala, James P. Higham, Michael Heistermann, Karen J. Parker, and Dario Maestripieri set out to test the hypothesis that maternal rejection during the weaning period elicits both psychological and energetic stress on primates. They predicted that elevated concentrations of fecal glucocorticoid metabolite (fGCMs) would be associated with…
