Dung Flies Adaptation

1 I have been studying the traits and dispositions of the lower animals (so-called), and contrasting them with the traits and dispositions of man. I find the result humiliating to me. For it obliges me to renounce my allegiance to the Darwinian theory of the Ascent of Man from the Lower Animals, since it now seems plain to me that that theory ought to be vacated in favor of a new and truer one, this new and truer one to be named the Descent of Man from the Higher

All throughout history, humans have come up with innovations that have brought both positive and negative changes to the way people live. This all started around 10,000 BCE, when people developed agriculture. The first nomads started off by moving from place to place, hunting and gathering food… but as people developed agriculture, they saved a lot more time. After agriculture developed, the humans learned many things such as farming and taming wild animals for their own use. This time in history was called the Neolithic Revolution… which lasted about 6,000 years, until 4,000 BCE. The big change in the way people got their food and how they lived, resulted to positive and negative changes of human innovations of the Neolithic Revolution. So,

Conformity: Adjusting one’s behavior or thinking to coincide with a group standard. In the movie, when Judy said that she though that the predator’s attacks were due to genetics, everyone conformed to this idea. The prey started to separate themselves from the prey and conform to this idea.

Trait theories assume people have many traits that are continuing qualities that individuals have in different amounts. Allport’s theory suggests that there are 3 main traits: central, secondary, and cardinal. A central trait is a characteristic that controls and organizes behavior in various situations. A secondary trait can be described as a preference and is specific to certain situations. A cardinal trait is very general and pervasive. It is so pervasive that an individual is governed by it and it dictates everything a person does.

From the early prehistoric society until now, we often heard the word “adaptation”, which means the process of changing something or changing our behavior to deal with new situations. The ways people adjust their natural environment varies according to time, place, and tribe. Foraging is common way of adaptation that people uses for most of human history; however because of the population pressure, some people adopt agriculture to fulfill their need. This essay, will discuss the positive and negative aspects of life in hunting and gathering societies compared to the agricultural societies based on Martin Harris’ article “Murders in Eden” and Jared Diamond’s article “The Worst Mistake in the History of Human Race.”

Protecting communities is another biologic adaptation that emerged from chimpanzees. As humans began to evolve, their ability to fight grew through natural selection. As time went on, human evolution favored traits of cooperation over physical attributes. This emphasis on teamwork lead to a species keen on teamwork and strong desire to protect each other, while growing hostile towards outsiders. This can be seen in the early struggles between Neanderthals and Homo Sapiens, and continues to be evident throughout early human

Prior to living in homes build to with stand the test of time, growing food their food source, and raising animals, humans were nomads who followed their food source around and were hunters and gathers. Although it took many years, from 8000B.C. to 3000B.C. for humans to go from hunters and gathers to a more common day life as we now know it, the result is referred to as the Neolithic Revolution the begins of human civilization. As the people of this time began to settle down and they began to both farm the land and domesticate animals for the better of the community. Along with the development of these communities as for the first time began to create social class among the many different roles they played in their community. Because

In this experiment, vestigial flies as well as wild type flies were used to create some diversity as well as test one of our hypotheses. Our hypotheses are as follows; 1) The wild type flies will have a greater relative fitness compared to the vestigial flies based on only sexual selection.  The wild type has a relative fitness of 1 since it has fully functional wings.  Vestigial Winged flies are not as sexually appealing since their wings are not functional and the wing movement is a vital part of their mating ritual.  2) The vestigial fly will have a greater relative fitness when considering both sexual and natural selection. With the presence of

The lifestyles of people in different societies are becoming more similar over time because of

Adaptation is the ability to adjust for existence under environmental conditions. Like how animals adapt in the wild, humans are also capable to be tolerant in difficult situations. We do not know our limit of cruelty or kindness. Although most people choose to be kind and sympathetic to others, there are also people who are cruel and cold-hearted. Mark Zusack states this idea in his book, The Book Thief from death’s point of view, “That’s the sort of thing I’ll never know, or comprehend- what humans are capable of.”

we said goodbye and placed them in the fly morgue. We allowed the F2 larval

There is a fundamental human need to belong to social groups especially if people were to live and work together, it is likely that they need to agree on common beliefs, values, attitudes and behaviours in order to get along and fit-in. Thus, we learnt to conform to rules of other people, the more people see others behaving in a particular way or making particular decisions, the more likely people will feel obliged to follow the suit. This is called conformity and can be defined in different ways, Aronson, Wilson & Akert (2014) stated it is the changing of one’s behavior due to the real or imagined influence of other people. According to Deutsch and Gerard (1955), social influence should be distinguished into two types, the informational social influence and normative social influence. The occurrence of social influence has implied to many real life events, which has drawn many researchers to attention. This has lead many researchers to design distinct experiments to try and understand the cause of the conformity, whether conformity is situation dependent, and whether we are able to resist social influences.

Humans are the most unique species on Earth. We have gained the ability to things never accomplished before on Earth. We can control our environment, domesticate other species, and more importantly, form complex connections and societies with one another. However, it is widely debated about how we evolved from simple ape-like foragers to the meat-eating, community-building species we are today. In this paper, we will be looking at three authors: Richard Wrangham, Pat Shipman, and Frans de Wall. Each of which approach this question from different directions.

Furthermore, the denizens of society are tied to the rules of Social Darwinism, as they are subject to the same fashion of natural selection as animals in the wild. Instances demonstrating Social Darwinism, the notion that humans are subject to the same fashion of natural selection as animals in the wild while living in society

To study the evolution of human behavior, we must first understand the evolutionary foundation of modern human behavior. Using the knowledge we have about human behavior while observing for patterns that are consistent with evolutionary models. Taking advantage of natural experiments that produce different combinations of variables that can allows us to obtain new approach on human behavior. This chapter will focus on various aspects of human behavior from an evolutionary viewpoint. These involve the “ecology and demography of traditional human societies, patters of human behavior that have been shaped by sexual selection, the interaction between culture and biology in the expression of language, and the emergence of behavioral disease in an
