Over the years, it has been historically difficult for people to come to terms with the fact that human beings are just another primates and the difference is just the substantial degree from some of the others. The comparison of the minor anatomical differences between human and apes have been identified to be the result of habitual bipedalism. The link between the now-human primates and the human is a result of evolution that occurred in the form of locomotion. In most of the world, nonhuman primates have been the topic of discussion. It has been identified that the first primate that was spotted appeared 60 million years ago (In Duggirala, In Almasy, In Williams-Blangero, In Paul & In Kole, 2015). The research is usually done in contrast as the existence of humans become to be known only about 5-8 million years ago. It is, therefore, an indication that for more than 50 million years ago, humans have been sharing primate ancestry. The fact that nonhuman primates had shared ancestry in the past with humans is what contributes to the similar characteristics that they possess.

Evolutionary Link Between the Human and Non-humans Primates

After the human species evolved to form the bipedal type of species, human, and nonhuman apes have been viewed with psychological characteristics. The way the human brain and the nonhuman primates are organized is similar especially in the vision system. Nonhumans just share the organization of the brain, and the study of the neuroanatomical structures is what has been used to connect the primates to the human being (In Duggirala, In Almasy, In Williams-Blangero, In Paul & In Kole, 2015). Nonhuman primates, therefore, serve as the model that involves a lot of processes that would be tough should the human being be involved. The understanding that the research gives on the different systems of the human being like the reproduction systems which is a biological phenomenon is what promotes the relationship and the links.

Apart from the understanding of human beings, the study of nonhuman primates is also portraying the existence of different behaviors and lifestyles. Most importantly, the wide range of habitation is more than fascinating as they are also studied for fascination. Primates' actions include that of humans in some circumstances, but the differences are outstanding in the behavior and other structure. It is wise that there is an understanding of the interactive relationships between the behaviors and also the environment in which the humans and the primates live (Liebal, Muller & Pika, 2007). Nonhumans have got their specific type of food and so do humans.

According to evolution, human beings evolved from the apes, but the natural selection and the difference in the environment contributed to the changes in the physical features. That is why humans have got relatively short and weak compared to the legs. The human pelvis is stronger since it offers support and stability as the humans walked and ran. The comparison of the humans and the nonhuman primates have been autonomous since the genome of the primates like the chimpanzee was done in 2005 and the result of the test revealed that the primate had 48 chromosomes while the human has 46 chromosomes(Abee, n.d.). The results, therefore, reveal that the pairing of the DNA sequence in humans and primates are the same. Most of the 4% that would be found would either be due to the duplication of the non-gene segments.

The modern human being in recent days has got a brain capacity that is three times bigger in volume than those of the greater apes. Research has indicated that the fact that human beings have got a high capacity of intelligence, exists as evidence that the brain undergoes what is referred to as revolution. The changes are the evolution said to have been around 6 million years ago (In Duggirala, In Almasy, In Williams-Blangero, In Paul & In Kole, 2015). Most research has been done, and more emphasis has been given to the DNA nucleotide sequences of the living primates species to show that there is the existence of the human as a close relative of the apes.

The reason the nonhuman primates are a student is cognitive as it helps the researchers to understand the mechanism that develops the human brain since the research cannot be done on humans, the research on the apes would create the discovery. The studies cover the anatomical and electrophysiological studies of the human brain (Liebal, Muller & Pika, 2007). It has also been revealed that due to the close genetic relationship between the nonhuman primates and humans, diseases causing organisms can also be passed between them. The research is therefore done on nonhumans primates in order to decide how they can be isolated and the human who takes care of them as pets to be careful and be aware of the risks (Abee, n.d.). The interaction between the humans and the nonhuman primates have a history of disease transmissions like the local wound infection, enteric diseases, Simian Immunodeficiency Virus(SIV), and Marburg and Ebola.


The close evolutionary link between the human and non-humans primates such as the rhesus, cynomolgus, macaques, squirrel monkeys, capuchins, baboons, and marmosets are carefully monitored for their developmental activities. Research is also done to examine how a particular tissue can result or react to different treatments and diseases so that the safety of humans is obtained. So that the researchers can be acquainted with the culture and the evolution of humans, they have to study the culture and the different dimensions and structures that are illustrated by the nonhumans.
