Homo sapiens also known as “wise man” in Latin or in other words the binomial nomenclature scientific name for the human species. One of the most hotly debated issues in paleoanthropology focuses on the origins of modern humans, Homo sapiens. Specifically where did we come from or evolve from. There are several ideas of where we originated or came from depending on how you view it such as a religious view or scientific view. For this purpose we will be discussing the scientific view methods which include the regional continuity method and the replacement method.
1.5 to 2 million years ago there was the Homo-habilis species. The earliest form of man. They were the first 'great apes.' 500,000 years ago lived the Homo-erectus species. They lived during the Pleistocene period and are considered the first homo species to walk upright on two legs. Then came the Neanderthal (about 100,000-30,000 years ago). They were very primitive and animalistic, but they lived in groups, wore clothing, used fire and made basic hunting tools. They got their name from Neander Valley, the location in Germany where they were first discovered. Next up in the evolution process was the cro-magnum or early modern humans (40,000-10,000 years ago). There cranial features were elongated to allow for a larger brain, more evolved tools and grinding rocks and the developers of religion.
There are 2 theories for the origin of modern humans. One of them is the replacement theory or “Out of Africa” model by Stringer. According to Stringer a single African origin of Homo sapiens occurred about 200,000 years ago. The most recent wave of African migration, based on mitochondrial DNA analysis, proposes that a small group of modern humans left Africa about 70,000 BP, replacing all earlier populations throughout Eurasia and Australia, and eventually North and South America.

Human Resource Management in Modern World

...manager is at the centre of the organisation’s web of employees and departments. Here are three ways that HR has a direct influence on the success of the business. Supporting the business The HR function must adapt to what the modern business needs – a highly dynamic employee management and planning team that can react and adapt to the rapidly changing requirements of the organisation. HR should be considered a strategic, integrated position that directly influences the business’ success because HR works so closely with its human capital – the organisation’s true competitive advantage and central value offering. By managing current, incoming and outgoing employees, HR ensures the company always has the right people for the right jobs. Employee engagement HR should no longer be seen as an employee’s last resort in the case of negative encounters – in fact, modern HR should be defined by active engagement with employee issues, championing staff members in the workplace, listening to concerns, and building a partnership between HR, employees and managers. Managing expectations, communicating, being flexible and providing adequate training are some of the most important factors in keeping employees happy. HR managers can go further, too – performing human-centred performance appraisals, actively driving career development and upskilling, developing effective reward systems and designing jobs to fit both the employees and the needs of the business. Taking an active and......

The Origin of the Modern World

...1. “I was persuaded to stop writing that book. I started it four more times during the next twenty years. On each occasion, my decision to begin again was influenced by current world events: the U.S. invasion of Panama in 1989, the first Gulf War, Somalia, the rise of Osama bin Laden. However, threats or bribes always convinced me to stop. In 2003, the president of a major publishing house that is owned by a powerful international corporation read a draft of what had now become Confessions of an Economic Hit Man. He described it as "a riveting story that needs to be told." Then he smiled sadly, shook his head, and told me that since the executives at world head-quarters might object, he could not afford to risk.” The statement above was very appealing to me, I think it is because my family is constantly talking about how twisted our government truly is. The fact that there was something to hide so they persuaded him to stop writing it makes me realize how intimidating they must be. And then how he talk about all the wars, invasions, and other twisted things he was discussing made some one scared to publish the book even though they believe he needed to be said. 2. “This book is the confession of a man who, back when I was an EHM, was part of a relatively small group.

Universal and Human Origins

...ENGL 212. September 21, 2012 Universal and Human Origins According to several essays in the Longman Anthology of World Literature, there are differing views as to how humans originated. One essay stated that the heavens and the earth were first created. Then the creatures that fly, next were the creatures that live on the earth and those in the waters were then created. Then God said, “let us make a human in our image and likeness to hold sway over the fish and the fowl of the heavens and the cattle and the wild beast and all crawling things upon the earth.” He created a male and female and then he blessed them. He then said to them, “be fruitful and multiply and fill the earth. So the first couple was told to have children and fill the earth with offspring (Genesis, chap. 1). Other writing such as Jacob Carothers Intellectual Warfare perspective on the origin of human was more of a mythological stand, which dealt with more than one God Zeus and the Titians. For many years Scientist, archeologist searched for the origin of mankind, many years of research has gone into finding out the big mistery of where do and how was this earth created? Genesis, chapter two elaborates that the man was created first and since God did not want him to be alone, he created the woman and he used one of the man’s ribs to do so. Genesis, chapter four introduces the first child, Cain who unfortunately kills the second child, Abel. In Genesis chapter five we learn that the third......

Modern Society Human Populations at Risk of Disease Pandemics

...Modern society human populations at risk of disease pandemics Sandra Mankarios 42460441 Word count: 2033 The qualities in which humans in modern day society live have increased the potential risks of the transmission of pathogens and their vectors. These risks have become limitless compared to the past; the damage created now will greatly effect future generations where the damage may even be irreversible (Washer 2006). Many factors in everyday modern life contribute to the rapid spread of pathogens and their vectors, which include the advances in modern transport via the air, land and sea, the increase in population size and density, global change and climate change. These features of today assist in the introduction of new diseases and also the re-emergence of old diseases including influenza, HIV/AIDS, dengue fever, malaria, severe acute respiratory syndrome (SARS), Cholera and many others (Tatem et al. 2006). MODERN ADVANCES IN TRANSPORTATION In the past, populated establishments were isolated due to lack of efficient transport. Now in today’s modern society, the constant advances in resources and the requirement for travel has seen the travelling of individuals dramatically increased over the years. Transport systems via land, air and sea continue to develop allowing swifter mobility of passengers and goods across vast distances within shorter periods of time. Although this is exemplary of an advancing society full of promising travel and freight options,......

Hall of Human Origins

...Humans belong to the species Homo sapiens, which is a member of the subgroup Homininin (Rasmussen, 1993). Along with chimpanzees and gorillas, humans belong to the subfamily Homininae. Fossil evidence and genetic studies show that humans and chimpanzees shared a common ancestor dating back millions of years ago (Rasmussen, 1993). Four trends led to major evolutionary changes and the development of Homo sapiens. The Hall of Human Origins is an exhibit at the National Museum of History that summarizes the changes that sets us apart as humans. The path to becoming human began 1.8 million years ago when our ancestors started to walk upright. The first major change to occur was the development of a bipedal structure. Initially our early ancestors walked on four legs while on the ground and climbed trees. Changes in anatomy such as reshaping the hips, skull, and lower limbs resulted in an upright body, longer stride, efficient gait, and the ability to run (Blaxland and Dorey, 2012). The second major change occurred when human ancestors developed shorter jaws and smaller teeth. The canines became shorter and rounded and the less protruding jaw allowed the face to become more vertical and proportionate (Blaxland and Dorey, 2012). One of the more significant changes that occurred was the development of a larger brain size. Early on about 3 million years ago the brain size of our early ancestors was very similar to the modern chimpanzee. The dramatic change in size led to...

The Evolution of Modern Humans

...The Evolution of Modern Humans Two origins are considered when thinking about the evolution of modern humans. There’s the “Multiregional Model” that concentrates on a multiple origins theory in which the different human populations or races had independent origins and evolved in isolation from each other, and there’s the recent single-orgin hypothesis or the “Out of Africa” which holds that anatomically modern humans evolved in Africa between 200,000 and 100,000 years ago. With this theory humans started to leave Africa after evolving. Both theories support that human evolution began in africa, but the “Out of Africa” theory has gotten much more support over the last decade, but there are still many people who support the the multiregional hypothesis. Until the recent years the only way to the only way of learning about ancient ancestors was through old fossils and stone tools. The “Multiregional Model” is the older model that consists of several models of human evolution which all posit that the human races evolved from separate archaic humans over millions of years. The “Multiregional Model” posits that 1.5 million years ago marked the beginning human evolution and that fossil samples represent the the evolving of homo sapiens. According to the theory there is no one place where homo sapiens evolved. They may have developed in Africa and then spreaded, or maybe they started in Europe and Asia and spreaded from there. Support for Multiregional The fossil......

On Origins

...“On Origins” Neveen Hirmiz Prof. Cary S. Tagasaki Word Count: 612 209641051 06/02/14 "On Origins" It is the world's longest and most massive structure built by man, its name The Great Wall of China. As early as the Qin Dynasty we see these tamped- earth structures representing a defensive fortification for the people of China. Since then, future generations have altered the Wall’s image, both physically and ideologically, through the cultural interplay between material reconstruction and historical reinvention. It is this process that Carlos Rojas believes most significantly defines the Wall’s identity, and is directly responsible for the preservation of the physical structure itself. Carlos Rojas suggests that it is important to consider the historical context of the Wall to appreciate its various meaning throughout history. He refers to the different Chinese anniversaries being commemorated, in which they all helped to shape the culture, society, and politics of modern China. At the same, the different ways in which the anniversaries are observed demonstrates the role of contemporary concerns in shaping a vision of the past. Over many generations, ideas are developed about forming the wall, in that different representations of the Wall add to the body of tradition, in which it allows for its historical longevity. Rojan states, the way that the Wall is commonly perceived today is largely influenced by recent attempts......

Humann Origins

...Jeffrey Domond Biology 112 Human Origins Around six or seven million years ago in Africa, our first members of our human family the Hominidae was created in Africa. During through the six or seven million years ago, they spent much of their time in trees, like there close relatives the primates. Once the early hominids went on ground they stood and walk on two feet. That separated them and the primates. Homo sapiens evolved in Africa more than 150,000 years ago. To understand the history on how did human evolved and how they adapt to their setting. Scientist relies on evidence including fossils, artifacts, and DNA analysis. By understanding these clues and exploring the data it is clear how much we are evolved from one period to the next. In the exbiht Human Origins at the Natural History Museum fossils and DNA gave clues about the earliest members of the human family. Humans were thought to be most related to chimpanzees and bonobos. But the DNA of humans and chimpanzees is 98% the same and 2% different. Many scientists believed the 2% occurred when hominids evolved from living in trees to adapted living on the ground. DNA is considered the identifying mark of a living system such as the human evolution tree. The DNA code is complex in its basic structure. DNA is a double helix structure molecule. It’s like a long ladder and twisted into a spiral structure. DNA molecules are sugar and phosphate forms the sides of the ladder. DNA has four bases: adenine, thymine,......

Darwin's Origin

...Q1: Darwin's Origin consisted of two parts. The first described observations in support of common descent, the second a mechanism to explain how it was the case. Provide examples of the observations Darwin used (1 page). ‘On the origin of species by means of natural selection : or, The preservation of favoured races in the struggle for life’ by Charles Darwin (1860) was the first book to put forward the scientific theory that populations evolve over a period of generations by the process of natural selection. The first part of the book described observations in support of common descent. One such observation is that of the homologous structures possessed by a wide variety of animals. Darwin used the fact that lizards, bats, whales, birds, frogs cats and even humans all contain a pent dactyl limb to support his theory that all life is descended from one common ancestor. As he says himself , “What can be more curious than that the hand of a man, formed for grasping, that of a mole for digging, the leg of the horse, the paddle of the porpoise, and the wing of the bat, should all be constructed on the same pattern, and should include the same bones, in the same relative positions?”(Darwin 1860) Another observation of common descent from the first part of Darwin’s book is that of convergence of form. This is the presence of similar biological traits in members of different species. Darwin illustrated this using the example of the finches. He observed a variety of forms......

The Origin of the Moon

...The Origin of the Moon: discussion on the gradual perfection of proposed hypotheses Introduction The Moon is the easiest and most familiar object that human can catch in the clear night. The Moon as known as our Earth’s only natural satellite is indicated by Rick Carlson in recent research to have an age of between 4.40 and 4.45 billion years, which is not long after the origin of the Earth. However, the origin of the Moon is still not defined and further research on this topic is continuous. The exploration of formation of the Moon is gradually per fected by the various proposed theories started from 1878 to nowadays. This research essay will discuss both the past and present hypotheses of origin of the Moon. The past hypotheses also known as “The Big Three” referring to Fission, Capture and Accretion hypotheses are popular in different times and centuries before the Apollo mission flew in 1972 (Tyson, 2000). However, the study on the moon rock brought by Apollo’s program gives unavailable clues for “The Big Three”(Tyson, 2000). Nowadays, the Giant Impact Hypothesis is regarded as the most leading theory that is most accepted in present. Nevertheless, it is widely accepted, some studies supported this theory; others may create new theory to challenge this Giant Impact Hypothesis, which make this hypothesis still arguable. However, whatever these hypotheses failed or will achieve, they bring a better understanding on the formation of planet’s satellites in our Solar System......

What Does It Mean to Be Human in an Age of Modern Technology?

...What Does it Mean to be Human in an Age of Modern Technology? What does it mean to be human in the age of modern technology? Many feel that technology is only a useful tool and has not changed what it means to be human. Others argue that today’s technological advances have become so rapid, sophisticated and ingrained in daily life it is taking away from the interest, welfare and humanistic nature of our society. Most all do agree that technology has certainly played a role in humanity’s social and behavioral progress throughout history. However, to what extent technology really drives the development of our social and behavioral changes can elicit a heated discussion. Humans are driven, curious creatures that seek to solve problems and have a need for social interactions. As well they desire some form of system of belief (though not necessarily religious in nature) and aspire to be part of something collective or feel a sense of purpose to life. Countless studies provide that human behavior arises out of the interaction between individuals and their environment. Although environments do influence human behavior, many contend the basic tenets of humanity such as compassion, the need to have connected relationships and the desire to improve upon our lives have not changed in the face of technology. However, it is clear that human attitudes and expectations today are certainly very different than even several generations ago. Much of which, is a direct result of......

...diversity, and functional diversity. Biodiversity makes up the structure of the ecosystems and habitats that support essential living resources, including wildlife, fisheries and forests. It assists in providing for basic human needs such as food, shelter, and medicine. It composes ecosystems that maintain oxygen in the air, enrich the soil, purify the water, protect against flood and storm damage and regulate climate. Biodiversity also has recreational, cultural, spiritual and aesthetic values. ( I grew up thinking that, for the most part, skin color was indicative to ethnicity. However, I have always wondered why people from different parts of the world had different colored skin and facial features. Most of us can look at a person from China, examining their skin color, hair texture and facial features, and know they are Asian. But, how does this happen. How did people from Asia come to look like they do? We know that humans have mostly naked skin that comes in all different colors. It has also been discussed that the distribution of skin colors among indigenous populations is not completely random; darker people tend to be found nearer the equator, lighter ones closer to the poles. Modern humans evolved in Africa between 120,000 and 100,000 years ago and had darkly pigmented skin adapted to the conditions of ultraviolet (UV) radiation and heat that existed near the equator.

On the Origin of Evil

...On the Origin of Evil Where does evil come from? This is a question that I find most interesting. In our modern day civilization educated by liberal institutions everybody speaks as if they are certain of what evil is. So what is it? At first glance the thing that sticks out to me when I hear this question is: Asking where evil comes from is like asking where hunger comes from. Where does the desire for procreation, for sexual reproduction come from? Is a lion evil? I am sure it could be viewed as such in the eyes of a gazelle. Lions kill other lions indiscriminately. They will kill young and old alike in competition for food, mates, or territory. Should every creature have the disposition of a humble lamb? Is a human being killing another human being evil? What if it’s a matter of self-defense? What if one acquires glory or good fortune for oneself and one’s people by killing? King David rose to glory and won the battle for the Israelites by killing Goliath. As stated in 1 Samuel, “Saul has slain his thousands and David his tens of thousands” (ch.18 v.7: via Bible Israel’s prosperity was only made possible because King David was a masterful warrior king that won many battles. Likewise war and conquest played a vital role in the founding of our country. And we became an economic superpower because of the good fortunes that came as a consequence of World War II. In this light killing could be viewed as a good thing. Accordingly things are only good or bad......
