Charles Darwin was the first person to suggest that animals may be useful for further understanding the biology of human beings when he created his Theory of Evolution in the 1800s. This theory eventually led to Louis Pasteur testing on a sheep in the late 19th century which was the first major test to be conducted on an animal (Murnaghan, Ian Animal Testing Timeline). Pasteur administered an anthrax vaccine to the sheep to test his germ theory, which showed the importance of vaccines to combat…

consideration of the relationship between the Intermembral index and the habitual mode of locomotion for the six different primates, the collected data suggests that the lower the index is, the greater the chance for bipedalism as the “default,” or main movement. Versus a higher index which instead suggests the preferred ability of moving with the arms (e.g. swinging). Moreover, primates with an index closer to a total of 100 appear to assume quadrupedalism. This query can be seen when closely…

The two papers Understanding vertebrate brain evolution and Comparative primate neuroimaging: insights into human brain evolution look at the evolution of the vertebrate brain. Both papers recognize the value of comparative studies to facilitating the understanding of the brain. While knowing what changes have occurred in the brain is insightful, knowing how and why those changes have occurred is necessary to have a comprehensive understanding of the vertebrate brain. The ultimate goal is to…

scientist are finding new evidence on how we all came to be as humans. The starting point has always stayed the same though. We evolved from a from a special type primate. It all started when our ape ancestors started walking on their back legs changing their posture and also changing their minds. Australopithecus afarensis were primates that were proven to be closely related to the modern human species. They had ape structure at most parts of their bodies like their hands, arms, chest and…

closes to human ancestor are primate- Chimpanzees are one of the typical primate example. According to worldwifelife, chimpanzees “share about 98 percent of our genes.” (“Overview”, n.d.), which indicates the high likelihood of change for chemical testing. Conlee and Rowan (2012) indicated that Chimpanzees have their “cognitive and emotional abilities”, mathematical, memory and problem –solving skills” which are similar to human. Likewise, it is express that nonhuman primates, carnivores and…

idea of a man living with what I thought of at the time as monkeys. Much time has passed since then, and as I grew older, my perspective changed on what I once thought were noble beasts. After watching films like King Kong and reading of villainous primate masterminds in comic books, I idolized them for a different reason, and respected them for their strength and savagery. However, as my views again changed, I realized that these animals are extremely intelligent, nurturing, and…

in 2004 in the publication “Primates and philosophers” along with other critiques of ethics and empathy across species differences. He called for “intellectual breathing room”(60) which is gained by assuming that “ instead of empathy being an endpoint, it may have been the starting…

These primates had the same dental formulas as modern Old World monkeys and apes, but they lack other derived features associated with Old World monkeys. The largest and most famous of the propliopithecids is named Aegyptopithecuszeuxis, who is known from several…

2002). The experimenters state the way the monkeys interacted with the toys resembled the sex differences in children and their toy preference. It indicates that toys hold different standards between females and males for both humans and nonhuman primates (Alexander & Haines, 2002). Therefore, it supports the hypothesis sex differences in liking for certain toys can occur…

chimpanzees are our closest living relatives and we share similar DNA, we evidently develop completely different learning and socials skills than them. I think by studying this process it helps us give a broader idea and aspect to the evolution of both primates and humans and how we connect…
