The latest period of human evolution begins with the arrivals of Homo sapiens. Today Homo sapiens are known to be the modern humans. The structure of the Homo sapiens is unique among any other Homo species, because of changes in the brain size and skull. The average cranial capacity of Homo sapiens is about 1,300 cubic centimeters making it the largest brain size from other Homo species. The modern skull has a short base and a high braincase. The Homo sapiens first appeared in Africa about 200,000 to 300,000 years ago and began to migrate all over the globe about 55,000 to 60,000 years ago. In 1967, a team led by Richard Leakey discovered Homo sapiens fossils in the Kibish Formation near the Omo River in southern Ethiopia. In the discovery researchers found bones of two early …show more content…
Homo neanderthalensis have a brain size as large as ours but often larger. Neanderthalensis were normally shorter, had a robust skeleton, and had muscular bodies than modern humans. Their jaws were larger and more robust than those of modern humans and had a gap called the retro molar space, behind the third molars. They occupied a range of environment across Europe and the Middle East and lived through a period of changing climatic conditions. Homo sapiens occupied a range of environment across the continents of Africa, Europe, Asia, and Australia where they adapted to the tropical life. Another species that will be compared is the Homo erectus. The Homo erectus brain size was 1050 cubic centimeters, which was smaller than Homo sapiens. Homo erectus and sapiens had a similar structure of the brain. Homo erectus was able to adapt to any environment. In August 2014, a team reported that Neaderthalensis died out about 40,000 years ago. The reason why the might have been extinct was because the inability to adapt to climate changes, or the invasion of the modern

Apes and Mid-Life Crisis

...mid-age, much in the manner human beings do, recommending a biological interpretation for the midlife problem. Across several traditions, human beings inform a plunge in pleasure throughout their late-40s, a period when they usually sense less contented with their lives in comparison to their older and younger years. Chimpanzees also go through a type of midlife problem, discovered a new study. The astonishing outcome recommends that the blues of middle-age might be an outcome of biology, not tradition, and its evolutionary origins run profound (Ayers, 2008). The main reason for dividing the main body of this research paper as per the format given below is to investigate the various research papers which discus the midlife crisis between apes and humans. The paper will highlight numerous social and physical evidence and then carefully analyzes the findings of these research studies. Social and Psychological Explanations It has been stated in the socioeconomic theory that the hedonic adaptation, which...

Analysis of 2001: a Space Odyssey

...was portrayed and whether living on Jupiter for a sustained period of time is realistic. Finally, I will wrap up by delving deeper into the black monolith. I will discuss the plausibility of the technology and the initial reaction to the technology from life on Earth. The ending of this film is entirely open to interpretation, ranging from an explanation for Darwinian evolution to strictly religious thoughts of God or gods. Personally, I saw the black monolith as some sort of super-advanced alien technology that served multiple purposes. The first purpose, which was seen in the “Dawn of Man” section of the movie, was to assist in the advancement of an intelligent race. The monolith first appeared to the primates, before some of the early Homo species had arose. Shortly after contact with the monolith, one group of primates began to use a bone as a weapon. With the newly found weapons, one group was able to defend the water hole from another group. This suggests that the monolith had somehow inspired, whether through some sort of telepathic thought transmission or simply through touching it, the apes to begin using tools. The monolith had instantly advanced the primates towards further evolution. This was seen again in the closing scene of the film as well. The sole surviving astronaut, Bowman, is shown in a mysterious room. The scene keeps advancing and he keeps aging. Finally, in his deathbed, the monolith appears again. This is where the film went from weird/vague, to WEIRDER/VAGUER...

The Neolithic Revolution

Neolithic revolution…………………………………………………………………..6 4. Conclusion…………………………………………………………………………….9 5. Bibliography…………………………………………………………………………10 Introduction The most important technological development ever to occur in human history was the domestication of plants (agriculture) and animals (pastoralism). Together these developments are called the Neolithic Revolution. To understand how the Neolithic Revolution occurred it is necessary to understand the economic system it replaced. Until the Neolithic, and in most areas for a long time after, all humans engaged in an economic activity called "hunting and gathering". This system is called "food extraction" as opposed to "food production" by agriculture and pastoralism. This period, which occurred between 12,000 and 8,000 years ago, brought along many profound changes to human society and culture, including the creation of cities and permanent dwellings, labor specialization, the baking of bread, personal property, more complex hierarchical social structures, non-agricultural crafts, slavery, the state, official marriage, personal inheritance, and more. I’ve chosen this topic because we can’t imagine our life, if there were not such a revolution. What would we be without the Neolithic Revolution? I think without the Neolithic...

Evolution of Tool in Relation to Thinking Capability

...facilitates human’s thinking ability. The more diverse tools are used the more open thinking become. Evolution of tools describes how people’s thinking is changed by tool use, and how thinking becomes increasingly complex and systematic. Tool evolved from tangible tools, for example hammer, rope, bottle, to intangible tools, like academic theories, thinking techniques, and etc. Between these two extreme pole, there are some medium segments exist, such as Internet and other kind of technology. Tools improve productivity, they help people to expand in spaces and gain creativity, but some specific tools might constrain people’s thinking, and become an obstacle which rejects progress of thinking. Purpose of writing this paper is to illustrate how tool produce and too use facilitate people’s thinking, and this process will starts from material-based thinking, and then go into abstract thinking. Considering the historical fact of tool use, there will have a lot of archaeology or evolution knowledge involved. Moreover, all of these evidences will provide a powerful support for the main idea of this article.

Utilitarianism

...Utilitarianism ENG300 Information Literacy Assessment [Type the author name] This paper will discuss utilitarianism, its origins and how we can apply it to our lives today. I will show what would happen if everyone adopted this code of ethics and reasoning, and why I chose it.   Utilitarianism What is Utilitarianism? According to our textbooks, utilitarianism is the ethical system which believes that which is ethical is what will bring the greatest good or happiness to the greatest number of people (Turner, 2006). In a direct quote from the American Heritage Dictionary, utilitarianism is the ethical theory proposed by Jeremy Bentham and James Mill that all action should be directed toward achieving the greatest happiness for the greatest number of people (The American Heritage Dictionary of the English Language). Though there are many varieties of the view discussed, utilitarianism is generally held to be the view that the morally right action is the action that produces the most good. There are many ways to spell out this general claim. One thing to note is that the theory is a form of consequentialism: the right action is understood entirely in terms of consequences produced. What distinguishes utilitarianism from egoism has to do with the scope of the relevant consequences. On the utilitarian view one ought to maximize the overall good — that is, consider the good of others as well as one's own good (Driver, 2009).A well-known dialogue by Leonard...

...Session 1.3: The Evolution of Cellular Life Exam review view in a separate window In this session we focus on the natural history of cells and the evolutionary timelines of their appearance.  The modern phylogenetic classification of domains is used to categorize the different types of cells: bacteria, archea, and eukarya.  The names of periods and organisms and certain dates are often helpful in remembering or understanding events that occur in the natural history of evolution.  However, we do not expect you to know the names of all organisms mentioned nor all dates (you may find some of the sound attachments on complicated figures useful for review).  Those names and dates mentioned below are the ones to key on. The focus in this session is macroevolution which looks broadly at the time lines and changes over long intervals of time.  Remember that small changes over millions of years are the framework for evolving complexity from simplicity.    Summary of concepts and idea   An initial step in covering this material is an understanding of the different types of cells (prokaryotic, eukaryotic animal and plant), their differences, and their place in the phylogeny of life. 1.

...2013 Health Care Provider and Faith Diversity: First Draft Knowledge and acceptance are one of the two most important factors when discussing the diversity of faith expressions and belief systems of patients as a health care provider. For this assignment, I decided to research Christianity and one other diverse faith group; interviewing said friend about her faith, Naturalism. In the health care industry, health care providers whose spiritual beliefs differ from their own personal beliefs are a common issue. Learning how to appropriately and respectfully handle each individual’s diversity and faith or belief system is of the upmost importance within the health care industry. Interview Assessment Analysis When conducting my interview with my close friend, Asyia Aanandi, asking a wide range of questions on her faith was required for further assessment; furthermore, the best way to incorporate Asyia’s beliefs of a Naturalist toward her philosophy of providing care from the perspective of her faith. Asyia Aanandi’sAanandi spiritual beliefs are that of a Naturalist, believing in only one single notion; Homo-sapiens feel, think, and act on, due to “chemical reactions” inside ones brain and body. Naturalism is the belief that as humans, acting on ones desires is not only validated, but acceptable; to live the way one was created to be. All phenomenon’sphenomenons are explained through science, voiding out the very existence...

Through knowledgeable psychology was established from a powerful history of human beings that endeavored to acquire practical insight into one’s consciousness or demeanor. This type of study teaches what influences the behavior and mindset of men. Psychology has obtained roots in philosophy. There are numerous major schools of thought along with fundamental theories and assumptions which will be examined within this paper. Behavioral neuroscience or behavioral psychology involves evolution, heredity, adaptation, and ability to learn. The first psychology research laboratory ever launched was by Wilhelm Wundt that led to acknowledgement of psychology as a science in 1879(Peterson, &Nelson, 2011). In the early 1900’s it was thought that an individual’s environment affected learned reactions and behaviors. Maslow believed that people acquire and improve responses from incentives in their surroundings (Maslow, 1982). The Four Main Psychological Perspectives Are: The Psychodynamic Perspective This method was formed by a man named Sigmund Freud who thought ones actions dictated their mental thoughts or they were connected in some way (Robin Kowalski, 2011). Also he believed our mental...

Primitive Oppression of Female Sexuality

...Primitive Oppression of Female Sexuality Abstract This paper explores the complexities that come about when trying to transcribe female sexuality as a generalized symbol in our society. Explaining many different theories as too why our sociological mindset seems to be primitive when trying to justify the ideology that sexuality needs to be oppressed for females, when in contrast it is glorified for males. Theories also suggest that our brains are psychologically “wired” for male dominance, such as when observing our closes lineage on the dendrogram, chimpanzees and exploring their interactions based on gender and sexuality. While other theories suggest that it’s possible females physiologically aren’t made for as much sex as men are and that stimulates are needed to bring things to equilibrium, such as new clinical trial pills that will be the Viagra synonymous for women. Each perspective is thoroughly covered in this paper as all sides of the spectrum are hit to understand why such cultural stigma has been placed upon female sexuality, leading to the ultimate question; Will our primitive mindsets continue to be the oppressing weights females bare in society? Keywords: Sexuality, psychological, physiological, sociology Since the beginning of time woman have been viewed as the keepers of monogamy, vested with the responsibility of limited sexual desires and actions. Female sexuality had not even been referenced in the medical field as apart of the female psyche. In...

Argumentative Essay: The Role Of Women In Art

Early women in the world of art have been faced with challenges due to gender biases, often being encountered with difficulties when it came to training, traveling, selling their art, as well as even receiving credit for their own work. However, even with so many obstacles facing early women artists, some managed to be an exception and become successful fine artists of their time.

Commercialization of Organ Transplants

...Tissue Act 65 regulates every aspect concerning organ transplants (Schicktanz, and Chair in Bioethics (Ḥefah), 2013). Since its last amendment in 1989, there have been tremendous developments in medical science. Presently, organ transplants are nearly routine operations in various hospitals. Commercializing human part for transplantation has also seen an increase in demand for sperms, hair, plasma, eggs, among others. Even so, there are arguments for and against the commercialization of human organs such as marrow, kidney, and sundry, with both sides of the arguments facing criticism. It is imperative to investigate ethical aspects regarding commercialization of human organs. To reach a conclusion on whether it is ethical or unethical, this paper summarizes both sides of the argument and later presents a moral argument and rationale for commercialization of transplants. Without commercialization, there would be few potential donors willing to give out their organs to a dying patient who needs the specific organ urgently, which is contrary to human dignity. This is the moral argument in this report. Arguments for commercialization In 2009, a group of cancer patients, bone-marrow donation advocates, and parents filled a lawsuit against the US government. The federal law had banned buying and selling of human organs. One of the parents had three daughters suffering from a blood disorder called Fanconi anemia, whose treatment was bone-marrow transplant. In their argument, the plaintiffs...
