Evolution & NOS
• As the common thread in biology, the topic of evolution can help students make sense of diverse biological concepts. 4

Common Misconception about
Human Evolution
– Man evolved from apes or chimps… chimps… – No, Chimpanzees and humans had a common and less specialized ancestor
– Common Chimp = Pan troglodytes
– Human = Homo sapiens

In the Origin of Species, Charles Darwin makes reference to human evolution only once when he writes “light will be thrown on the origin of man and his history.”

It is of no surprise that much light or evidence has been gathered by paleoanthropologists – which include scientists who study human evolution – since
Darwin’s book was first published in 1859.

7

In the last two years alone, both in science/research journals and in the public media, there have been numerous scientific articles, news reports, radio broadcasts, etc. describing further evidence of human or hominin (which include present day humans and their ancestors) evolution.
The evidence collected ranges from new fossils being unearthed to new hominin species being described such as the discovery of the “Hobbit” scientific name:
Homo floresiensis on the Indonesian island of Flores
(Morwood, Sutikna, Roberts 2005).

How Climate Changes Have Effected Human Evolution

...How Climate Changes Have Affected Human Evolution Abstract This paper explores the link that changing climates and human evolution share. As climates change in the world then all living things must adapt accordingly or become extinct. I will go over some examples on how lifestyle changes were necessary for survival when climate these changes occur. 1 Climate changes can be seen around the world on a daily basis. No matter where you go you can hear somebody say the old phrase, just wait five minutes and the weather will change. Climate changes have been happening since the beginning of time and are not going to stop anytime soon. As human beings we have to adjust to the climate changes because the climate definitely is not going to adjust to us. In the article I decided review it talked about is how the climate has affected how humans have evolved. All kinds of climate changes can affect how humans and animal live on a daily basis. The article stated something that really made me stop and think. It said that when change happens, animals have a choice to either keep doing what they are doing now, become extinct, or change to adapt to the new way of life. (Smithsonian National Museum of Natural History. N.D.). This was so simply stated but encompasses everything about evolution. With all the climate changes in climate, even today, we are going to have to change the way we live in the future or eventually become extinct. ...

Evolution

...and make out thoughts real lie inside this complex system of bones, nerves and vessels.” –Neil Shubin These things would only be possible through evolution. Evolution is any process of formation or growth and development, without it we wouldn’t be here today. Evolution though only an theory has an massive backing within the science community; many fossils, scientist and scientific studies have all but proved evolution indefinitely. The proof for evolution is massive and profound; fossils and carbon dating are absolute proof that creatures very similar to us not only lived but were evolving and walking around. African hominids such as the bipedal Australopithecus afarensis or “Lucy” are some of the most profound examples of evolutionary history. Unlike a common monkey Lucy was a bipedal specimen which meant she walked upright much like an human. What makes her such an amazing discovery is the fact that she was about three-million to almost four-million years old. Scientist from every side of the spectrum have gathered to try to make this theory fact. Neil Shubin paleontologist and archeologist said” We were not designed rationally, but are products of a convoluted history”. The history of the human body is convoluted in every sense of the word; there are approximately three-billion-five-hundred-million years of history in the human body. Gunnar Save-Soderbergh another on the hunt for proof discovered what was labeled a major missing link; the fossils in question were......

Her boyfriend, Zach, was inspecting her skin very carefully. “Look,” he answered her, his voice taking on a more serious tone. “Today a woman walked into the clinic for her annual physical. Everything about her seemed fine. She leads a balanced lifestyle, she eats well, she exercises: she’s healthy! But as she was about to leave, I noticed a mole on her arm. It had many of the warning signs of skin cancer. So, I removed the mole. This woman now has to wait for the lab results to see if it was cancerous. If it is, maybe we caught it early enough to treat it, and maybe not. Either way, her life is changed. I just want to make sure you don’t have any suspicious moles, okay?” Tatiana relented and allowed Zach to examine her skin. She asked: “Do only white people get skin cancer?” “No, people of all skin tone can get skin cancer, but it does occur more frequently in Caucasians.” Questions 1. What are the causes of skin cancer? 2. Why are Caucasians more at risk of skin cancer than other populations? 3. At what age does skin cancer typically occur? Is the incidence of skin cancer greater in youth or old age? “The Evolution of Human Skin Color” by Annie Prud’homme-Généreux Page 1 NATIONAL CENTER FOR CASE STUDY TEACHING IN SCIENCE Part II – Skin Pigmentation and UV Light Why are human......

Evolution

...The beginning of the earth has been a mystery, boggling the minds of the erudite and the simple minded alike for years. The topic of creation vs. evolution has become increasingly controversial. In biology, Darwin’s Theory of Evolution is a change in the genetic material of a population of organisms from one generation to the next. Though changes produced in any one generation are normally small, differences accumulate with each generation and can, over time, become substantial changes in the population. Such similarities among species suggest that all known species are descended from a common ancestor (or ancestral gene pools process of gradual divergence). Evolution is supported in many different ways, but one major category pointing to its validity is fossils. Through fossil dating, hominoid fossils, and, evolution has become the theory accepted by the majority of those in the scientific forefront. Evolution is supported through fossil records. The study of the sequence of occurrence in rocks reveals the relative time in which organisms lived. This technique shows that one layer of rock is older or younger than another. Later through the discovery of radioactivity, scientists were given the opportunity to learn the age of fossils and rocks . Through these records, a vague timeline is illustrated of the evolutionary change that has been occurring over the past four billion years. This proves that the earth is much older then creationist would like to argue. A popular......

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......

Evolution

...Evolution within the field of Physical Anthropology is the Idea that “species change over time and have a common ancestry”(Park 2009, p36). With this in mind, the field of Physical Anthropology, also known as Biological Anthropology, can be used to explore and investigate the evidence of the human evolution. Within Biological Anthropology, evolution is observed as the change of humans and human ancestors over time. These changes that occur do not take place over night, nor do they happen over a decade. It takes thousands of years to produce changes in an organism to the effect that it would be classified as evolution. Physical Anthropologists study the remains of Hominins and other ancestors of humans to discover the link that connects us all. They also study other creatures to compare them to humans in an effort to understand where humans come from and what makes us human (Gonder, 2013). One way that Physical Anthropologists have found links of evolution from early Humans and Neanderthals is through dental evidence found and investigated by Professor Alan Mann. He concluded that modern humans did in fact evolve from Neanderthals by finding links in the dental history of each species. Though his evidence is disputed by some, like any other scientific evidence, there have been some that support him and have come to the same conclusion of the relationship between Humans and Neanderthals. One piece of evidence that supports his theory is from a group of researchers from......

Evolution of the Human Eye

...The human eye is an incredibly complex organ, it acts like a camera to collect and focus light and changes this light into an electrical signals that the brain then reads to form images. Instead of using film, the eye has specialized components such as the retina that detects light and process it using many types of neurons. The eye is so complex that its origin has long been a hot topic of debate and is often used to defend a creationist point of view, they say the eye is too complex to have evolved instead it must has been designed. The eye is a system that cannot function in the absence of any of its components. Even Charles Darwin remarked in the origin of species that ‘it might seem absurd to think the eye formed by natural selection’. (Fernald. R.) He did however firmly believe that the eye did evolve in this way, despite the only the small amount of evidence at that time. This evidence is hard to come by since soft-tissue structures like the eye rarely ever fossilize. However the scientific community has made recent advancements in tracking the origin of the eye by studying the formation of eyes in developing embryos and comparing these different structures and genes across many species to construct when and where key traits arose. The study indicates that ‘the human eye took shape in less than 100 million years, evolving from a simple light senor to sophisticated optical organ.’ (Lamb. T) Humans have an unbroken linage going back for 4 billion years. Almost a......

Evolution

...Evolution Abstract One paragraph… The discussion on the origin and fate of the universe continues to revolve around creationists and evolutionary ideas, though creationism positions arise mainly of religion and philosophy, while the evolution is postulated mainly from science. One wonders if possible convergence in these fields in the discussion, that is, if you can address both creationism and evolutionism from science, philosophy and religion. Theory of Evolution In science the theory of evolution explains the huge variety of life arising by postulating a process of transformation through changes in genes that lead to new adaptations to the environment. By studying the genetic structure of living beings is a verifiable fact that they are related to each other and, therefore, aims to have a common origin as the emergence of new species due to the accumulation of changes that do diverge and take different paths to adaptation to the environment. In the scientific world, biological evolution represents the interpretative key of the living world. Life began about 3500 makes 4000 million years in the form of single-celled organisms without nuclei and took about two billion years to produce the first eukaryotes (unicellular organisms with nuclei), so the start was given very slowly. However, in evolutionary history there are times with a high evolutionary rate as the Cambrian period (540 to 520 million years, they were many forms of multicellular life). They also......

Evolution of Human Resource Management

...ASSIGNMENT: 2 Evolution of human resource management Key principles and practices associated with HRM date back to the beginning of mankind. More advanced HRM functions were developed as early as 1000 and 2000 B.C. Employee screening tests have been traced back to 1115 B.C. in China and the earliest form of industrial education, the apprentice system, was started in ancient Greek and Babylonian civilizations before gaining prominence during medieval times. Since the inception of modern management theory, the terminology used to describe the role and function of workers has evolved from "personnel" to "industrial relations" to "employee relations" to "human resources." INDUSTRIAL REVOLUTION PHASE : The need for an organized form of HRM emerged during the industrial revolution, as the manufacturing process evolved from a cottage system to factory production. As the United States shifted from an agricultural economy to an industrial economy, companies were forced to develop and implement effective ways of recruiting and keeping skilled workers. In addition, industrialization helped spur immigration, as the country opened its borders to fill industrial positions. Filling these jobs with immigrants, however, created an even greater need for adequate management of employees. Early human resource management techniques included social welfare approaches aimed at helping immigrants adjust to their jobs and to life in the United States. These programs assisted immigrants in......

What Is the Theory of Human Evolution and What Evidence Appears to Substantiate the Theory?

...Evolution is defined as “any process of progressive change”; and the theory is complex life forms from our time have descended from earlier ones that existed long ago (Hunt, p.29). The theory of evolution was first made popular by Charles Darwin an English Biologist, he spent a good amount of his time trying to find evidence to support his many ideas. It is believed that the human species has its origins in Africa. Scientists share the belief that a human like creature originated from the apes and over time, through many changes the final result was a group of hominids, they do however disagree on when and why the different characteristics begun begun to show themselves. It had been discovered that humans and the other primates do have some differences, for one humans have a larger brain, we walk on two legs, go through a longer periods childhood and juvenile life stages, we have the ability to speak and to form culture (Parker, p.3). Evolution occurs through a series of processes, including sexual reproduction and mutation, where some more desirable traits may be passed on to the next generation either by chance or natural selection. Natural selection played a major role in the understanding of evolution, it meant that individuals that have traits more favorable to adapting to its environment are more likely to survive and pass on those traits to their offspring. This led to the notion of “survival of the fittest”. The trait selected to move on showed up in the next......

Evolution of Human Resources Management

...aspects of human behaviour in organisation. The understanding of human behavior was enhanced by contributions not only from the traditional disciplines of psychology, sociology, and anthropology, but also from social economics, political science, linguistics, and education. The interrelationships of these various disciplines are now referred to collectively as the “behavioral sciences.” The behavioral science approach is oriented toward economic objectives, concerned with the total climate, and consistent with the development of interpersonal competence. It is a humanistic approach. The use of groups and employee participation in the achievement of organizational objectives, including the management of change, is now a formally recognized field of study in universities worldwide. Managers draw upon the results of these studies regularly in managing staffs. It is not just an HRM field of endeavor. Managers worldwide apply the concepts in everyday activities. Many current management ideas and practices can be traced to the behavioral science approach. Some importance elements of behavioral science approach are highlighted below 1. Individuals differ in terms of their attitudes, perception and value systems. Therefore, they react differently to the same situation. 2. People working in an organisation have their needs and goals, which may differ from the organisation’s needs and goals. Management should achieve fusion between organisational goals and human......

Evolution

...Are Modern Humans Still Evolving?In the year eighteen fifty-nine, Charles Darwin published a book which he called “The Origin of Species”. In this book Darwin theorized that populations evolve over the years through a process called natural selection. Darwin realized that in a population, more individuals were born than could possibly survive, he also recognized that the individuals that survived and reproduced were the ones with some sort of competitive advantage over rival animals, therefore they were more likely to pass their useful traits down to their offspring (Darwin, 1859). As this process of natural selection occurred for millions of years, these desirable traits that were once only prevalent in a few individual animals became common traits for entire species (Winston, 2009). There are countless amounts of evidence that suggest that humans owe their existence to evolution, however, many people are skeptical as to whether or not it is still occurring, and whether or not it is happening in the same way. Some scientists hold that the human race has reached “its biological pinnacle and is no longer capable of changing” (McKie, 2005, ¶1). Alternatively, some experts believe that humans are evolving faster than ever (Sample, 2007), and others believe it is still happening, just on different terms. There has not been any deciding evidence as to whether or not humans are still evolving, however, saying it isn’t happening is a very difficult position to defend. Gene mutations...
