The study of human beings, human nature and human behavior has always been an area of interest ever since man began to think critically about his existence. This critical approach helped man to uncover reasons for the way that things generally were. Through these studies, man was generally able to understand the way that each human being thought and behaved, and these were based on one’s origin and culture in which each person was groomed. This is something that explains the way that people of different countries, nations, cultures, etc. behave differently.
Up to date, studies in this same area continue because there is still a great deal to be understood. In addition to this lack of understanding, it must be realized that even if things are all completely explained, these studies have to be sustained. This is because of the fact that evolutionary changes in the human race are most likely to bring about unforeseen transformations. Based on this understanding, it is no wonder that political anthropology also has immense interest in the way that biology of particular nations affects the way that they think and perceive the world.
The way that the modern world operates is a process of which sustained study is applied to practical life. Political anthropologists learn and understand the way that people from different parts of the world think and act. This enables them to carry out their actions accordingly; they (political anthropologists and those advised by them) act in accordance with the mindset of people with consideration for their area of origin. Statesmen with such knowledge learn how to manipulate people from particular regions because of the fact that they know how particular people would react to certain actions. They set up a number of possible reactions that particular people would have to their actions, and hence, further prepare to curtail those reactions. However, aside from the political and strategic implication of political anthropology, it is more important to focus on how much relevance ‘biology’ has in this subject.

Since political anthropology has grave interest in cultural aspects, it must be asserted that biological factors have particular bearing. This is because of the fact that biological development and cultural grooming take place as an intertwined process. This is due to the fact that they each reinforce each other. Traditions that are engraved in a particular culture are not easily erased, and a re most likely to be passed on from generations. In tandem, the consumption of food and behavioral patterns induce particular psychological features in human beings in particular areas. Hence, there is a chain to follow that may be briefly mapped as follows:
Origin > tradition development through random action > adherence to those practices through time > development of psychological and behavioral patterns through these traditions

Having briefly asserted the general historic pattern, it must also be pointed that variables that sustain psychological and behavioral actions are influenced immensely by things like types of education, food consumption, religious beliefs, cultural norms, etc. Each of these in one way or another influence one’s biology, and this is understood on the basis of physical and psychological developments being influenced by both internal as well as external influences. Hence, it may be asserted for example, that people who consume hot foods tend to think and act quicker than others who have a balanced diet; people who consume peppers tend to behave this way more than others who consume insipid foods.

In addition to food consumption, the amount of exposure to critical thinking is another example. This is exemplified in the way that people in the western hemisphere, particularly the US, tend to think faster and be more innovative. This does not undermine the genius innovations and inventions from the East, but certainly does explain the reason why one finds high profile statesmen more often than not emerging from western countries. It can be clearly seen that such statesmen and therefore such cultures being way ahead of others. The present situation in the world today is a prime example, and this is because the US can be recognized for its imperialistic approach, to which several others have succumbed.
Finally, it may also be stated that food consumption in the US is perhaps more than any other region in the world. The value of their food per unit as well counts significantly, as each unit is more valuable than others. This results in greater nutritional value, which means that it reinforces their physical as well as psychological condition.
