Four factors that limit the primate’s diet is plant defense, the reproduction status of a female, seasonality, and competition. Plants can use physical barriers to stop animals from eating them. For example, some plants will use thorns others will use certain substances that make digestion difficult, resulting in small quantity conception. Female primates who are pregnant require more calories, meaning they need to obtain more food. If they are lactating they require 50% more calories compared to when they are not breastfeeding or pregnant, according to the online lecture of Primate Ecology. Seasonality proves as a challenge due to food sources becoming scarce. Depending on their location primates may look at small sources that have calories that will help their dietary needs. Lastly, competition will occur when there is a small supply of food primates will compete. Once they begin to compete for the primate who cannot defend itself might not be able to obtain any food.…
The sciencemag.com article “Anti-Alzheimer’s Gene may have Led to the Rise of Grandparents” by Kelli Whitlock Burton talks about the how the protective variant of the CD33 gene may explain why humans have grandmothers that help with child rearing. The article explains the “grandmother hypothesis” that says humans live such long and healthy lives even after they are no longer able to reproduce because they help with child rearing. The CD33 gene plays a big role in Alzheimer’s disease and scientists Ajit Varki and Pascal Gagneux discovered that there are two variants of it: a protective allele and a damaging one.…
Either the Heron or Hawk and fish populations in the salt water marshes are a prime example of a predator-prey relationship; the heron finds its prey by walking or “waddling” through the shallow waters of the marsh and catching fish by striking them with the birds long neck and beak, swallowing the fish whole; and the Hawk with its powerful wings flies down and grabs the fish right out of the water (Also helping to control the area’s fish population.)…
Summary Response In the article “Of Primates and Personhood” written by Ed Yong, demonstrates major developments between primatologist, biologists, and ethicists around the world. These major developments are a pending spanish law that would grant unprecedented protection toward great apes; Also, a recent extension to a swiss law that protects the dignity of organisms, and to redefine the meaning of human rights, and indeed whether such rights are the exclusive domain of humans. Furthermore, the Great Ape Project (GAP) has been established (1993). Not everyone had been comfortable with the GAP’s project, says Yong;…
Before Jane Goodall’s discovery scientists believed that non-human primates lived simple life. It turns out that they are highly intelligent, emotional creatures that live in complex societies. This new discovery lead people to feel compassion and concern for the animals. Leakey’s once said “new we must redefine tool, redefine man, or consider chimpanzees as humans”. We now see that we are not alone with being advanced that there are other non-human primates that also are advancing.…
They flourished because of a high birth rate and the lack of effective birth control.…
Based on the results of the BLAST for the first unknown species only the first hit Perodicticus potto located in the rain forests in Africa with a pairwise identity of 100% has a high enough percentage indicative of the same species. It is therefore likely that this species belongs to an already known species and is not a new founded one. For the second unknown species the results indicate that all of the results including the top hit Cercopithecus pogonias nigripe of Western Central Africa had pairwise percentages of around 92% indicating it likely a closely related species and not the same species. The third unknown species BLAST results indicated from the first hit Pan troglodytes troglodytes of Central Africa and all the subsequent results were 100-99.80% indicating a very high likelihood of them being the same species.…
Primate socio-ecology varies and has different determinants that decide many different characteristics. As a virtual paleontologist, we discovered two different sites and skeletal remains in Kenya and deductively reasoned their mating habits, group size, and several other characteristics about the Praeanthropus dimorphicus and the Praeanthropus monomorphicus with what I know about primate socio-ecology. Based on my prior knowledge, logic, and reasoning, by looking at skeletal remains we are able to deduce many different features included in primate socio-ecology for these two different species that include: group size, diet, mating system, habitat, and finally ranging behavior and territoriality.…
Capuchins have traditionally been in the genus, Cebus Erxleben from the family Cabidae. There had been four species recognized among the capuchins, such as: Cebus albifrons, Cebus olivaceus, Cebus capucinus, and Cebus apella, all of which are a taxonomy that dominated capuchin history for an approximation of 50 years (Lynch Alfaro et al., 2014). Over the years more capuchins had been recognized as well such as, Cebus kaapori, Cebus libidinosus, Cebus nigritus, Cebus queirozi, and finally Cebus xanthosternos. In a physical sense, capuchin monkeys weigh around six to twelve pounds and live over five decades. In contrast to New World Monkeys, they have robust jaw and dental structures, large brains…
For example, he has observed how with female chimpanzees, they can be seen dragging males together to reconcile after fighting with each other. Along with females bringing males together, the elders in the chimpanzee groups can be seen as neutral mediators for disputes within their community (De Waal). This example of reconciliation and the way chimpanzees deal with it, show fundamental moral behaviors that can exemplify emotions that humans too exhibit between each other. In addition, the articles goes into concepts of empathy. De Waal uses a powerful example of an older chimpanzee named Peony that has arthritis, sometimes making it difficult to climb and walk.…
The animal that most resembles us is the ape. At the zoo, it is easy to observe behavioral and facial expressions in monkeys and apes that are very much similar to our own. A group of apes could very well seem like a family. A mother taking care of her young may seem familiar to the human onlooker. This is because the ape is our closest living relative. In the documentary Primate Behavior, anthropologists observe the behavior of monkeys and primates. The primates are mostly observed in the wild, as they are better understood while placed in a natural setting. This is where the social structure of the primate can really be interpreted.…
Primates are one of the most interesting mammals on earth, not only because of their complex social structures, but because they hold so many similar characteristics to humans. Primates are often cited as our closest living relatives and on two separate occasions I observed four separate species of primates at the San Diego Zoo that can justify their use of their physical characteristics and behaviors that may be similar as well as different to the other primates and ours.…
Humans are an extremely curious animal and are always trying to discover what capabilities other animals possess, whether the capabilities are the same or entirely different than humans the curiosity still exists. Human beings study and observe animals in the hopes of learning more about them, and sometimes in hopes of learning more about human beings of now or human beings of the past. People often study non-human primates just to compare their levels and types of intelligence to that of humans, such as looking to discover if they have or can learn communication and language that is comparable to that of human language. Knowing whether another grouping of animals, especially non-human primates, can have a complex language or system of communication…
Baboons and chimpanzees, who are famous for being closely related to humans, embody the symptoms of kindness among their peers. Within "The Selfless Gene", written by Olivia Judson involves the discussion and break down of the relationship between kindness and survival, as seen in humanly related species. The author states, “At the least, the evolution of social living requires limiting aggression so that neighbours can tolerate one another. And often, the evolution of larger social groupings is accompanied by an increase in these subtly and complexity of the ways animals get along together.”…”Consider baboons…baboons have evolved complex social lives.” (287) Judson goes into depth, explaining the many social skills that baboons are equipped with. One of these qualities is a pack mentality, which allows animals, such as the baboon, to perform best in designated groups for better chances of survival. Kindness is a byproduct of this sectional living. This behaviour can be compared to human activity in means of stating in a certain group or "herd". Judson discusses the importance of helping one another by stating later on in her passage, “Bowles shows that groups of supercooperative, altruistic humans could indeed have wiped out groups of less-united folk.” (289) Living in these groups can help lead others become kinder to one another, since they are with familiar people, in familiar…
Dutch primatologist and ethologist Frans de Waal once questioned, “If we look straight and deep into a chimpanzee's eyes, an intelligent self-assured personality looks back at us. If they are animals, what must we be?” Waal’s insightful query brings into focus the idea that we, humans, are all essentially “animals” with thoughts and behavioral traits that are unique to us. Moreover, he compares us to chimpanzees—a primate—for the reason that they are “intelligent” and “self-assured,” not unlike humans. However, despite the countless similarities between nonhuman primates and human beings, numerous species of “monkeys” are used in animal testing. Cruelty Free International defines animal testing as “any scientific experiment or test in which…
