Every species on earth has it's variants. For example, the differences between Wood Ducks and Mallards have evolved for specific reasons - namely, those which best ensure the survival of the Duck species in different environments. The same applies to humans. The Negro race has evolved under a certain set of conditions and those conditions differed vastly from those under which the Nordic Aryan race evolved. Whereas the Nordic Aryan needed warmth and shelter in the cold climates of Europe and consequently developed a more hairy body, light skin, and a narrow shaped nose among other things, the Negro, lavishing in the hot climate of Africa, needed cooling and therefore devoloped a flatter nose, a body with minimal hair, and a flatter, broader nose. This type of genetic diversity which has evolved over many thousands of years in order to better adapt us for our respective environments is being destroyed with miscegination - that is - "race-mixing".
As every species in the world developed, it's sub-species and it's further strains and breeds under those have evolved for a very specific reason - the preservation of the species, and ultimately, life itself. Each species is like a tree, with hundreds of branches, each leading to thousands of other branches. Each branch of the tree is slightly different from the one beside it, due to living in a different environment it has had to adapt and the resulting differences are due to the combination - the formula - of genes, which has survived the best in whatever environment it has encountered. Because of this branching of the species, whenever a particular disease, a natural phenomenon, or a new predator has arrived on the scene, the species has always been diverse enough to continue, as there will be one branch of the tree which has the immunity, adapted over time, in order to defend itself or escape from the catastrophe. This method, special branching, has ensured the survival of various species for thousands of years, and is in fact the reason for the existance of different species.
Since the beginning billions of years ago when God reached down and fused the base elements of life into a single-cell organism, that's how long this process has been taking place. As the amoeba of life spread to different parts of a world that was just beginning to take shape, it encountered different challenges for survival, the cells that couldn't survive died and the one or two mutated cells that could survive continued, multiplying and dominating each particular environment.
Osteoporosis is a condition, which advances with age, resulting in fragile, weak bones due to a decrease in bone mass. Externally osteoporotic bone is shaped like normal bone, however it’s internal appearance differs. Internally the bone becomes porous due to a loss in essential minerals, including phosphate and calcium. The minerals are loss more quickly than they can be replaced and in turn cause the bones to become less dense and weak. The bones become prone to fracture, due to their weakness. Therefore the awareness of the disease tends to occur after a fracture has been sustained. The bones most commonly affected are the ribs, wrist, pelvis and the vertebrae.
Osteoporosis is a condition, in which bones are weak from deterioration, loss of bone mass, and quality-bone strength. Osteoporosis usually triggers postmenopausal women (women who have not had their period for a whole year), or older men and women. Some risks both older men and women endure when experiencing Osteoporosis are decrease of calcium and bone fractures. These symptoms or effects can all be caused by weight loss, smoking, age, ethnicity, genetics, medications, bone structure, and certain diseases that can later on contribute to Osteoporosis, such as rheumatoid arthritis. Osteoporosis may be prevented by going to drug therapy to stop alcoholism and smoking, a sufficient amount of calcium intake, and exercising; such as jogging, walking,
Racism is often considered a thing of the past, with its manifestation rarely being acknowledged in the United States today. Race: The Power of an Illusion, is a documentary that addresses the legacy of racism through its significance in the past, and its presence in society today. To understand racism, it is vital to understand the concept of race. Race is a social invention, not a biological truth. This can be observed through the varying classifications of race in different cultures and time periods. For instance, in the United States, race has long been distinguished by skin color. In nineteenth century China, however, race was determined by the amount of body hair an individual had. Someone with a large amount of facial hair, for example,
The DNA code, that forms our genes, was the missing key for Darwin to understand how things evolved. DNA does not stay the same, it can be changed by mutations. Mutations are needed to generate variations. Without the mutations things would stay the same generation after generation. Pieces of DNA called a switch can turn certain genes on or off. Genetic Switches helps to create mutations which are sometimes responsible for an entire new species spawning from another. This is how a snake can evolve from a four legged animal, and how a whale 's front flippers has bones inside that resembles
There is a new trend hitting the market known as e-cigarettes, or “vaping.” Many people believe that e-cigarettes are better than traditional cigarettes, but research shows just how unhealthy and harmful e-cigarettes are for everyone. The FDA has not yet decided if e-cigarettes should be regulated like tobacco products. E-cigarettes are marketed to help people quit smoking and live a healthier nonsmoking life. E-cigarettes are meant to help break the habit of smoking, but why are there so many “toxic chemicals” (Gilger) in the vapor? Is this new invention to help people quit smoking or just another way for tobacco companies to get richer?
Evolution in general, is a hard concept to grasp. There are multiple factors that effect the outcome a species, for example: genetics, nurture, nature, and the environment all play an important role. It was once said that species do not survive due to the fact that they are the strongest or the most intelligent, but because that species is the most responsive to change.
Osteoporosis is a bone disease of that causes a decrease in bone mass. In osteoporosis the bones become weak and fragile. Since the bone mass is decreased, the bones have more of chance of fractures. The bone is continuously breaking down by cells which is known as osteoclasts and rebuilding by other cells known as osteoblasts. Osteoporosis happens once the reabsorption causes the bones to reach a fracture threshold. Any fall or lifting action that would not ordinarily bruise or strain the common person would break one or additional bones in somebody with severe osteoporosis. “Women of fair, freckled complexion with blonde or reddish hair, and women from northwest European background have a higher incidence of osteoporosis than the general population” (Rosdahl, 2012, p.1248). Osteoporosis most commonly happens in postmenopausal women. Some risk factors include age, menstrual status, smoking, sedentary lifestyle caffeine use, and alcohol consumption.
Race: The Power of an Illusion was an interesting 3 part film. After watching this, it made me questioned if race was really an illusion or not. It is absolutely taboo to think that the one thing that separates people the most may be a myth in itself. “We can 't find any genetic markers that are in everybody of a particular race and in nobody of some other race. We can 't find any genetic markers that define race.” (Adelman and Herbes Sommers 2003). Racism is something created in the U.S made to create supremacy for the creator. Racism is not just the way someone thinks, it is something that has is manifested in our society to separate us and can be traced to our everyday activities.
Through research of DNA samples, scientists have been able to declare that race is not biologically constructed due to the similarities between human genes. Nevertheless, in reality, people still emphasized on biological aspects such as skin color, or hair texture to categorize others into different races. This in turn, denied the true identity of race, which it is culturally constructed. Ethnicity, by definition is also culturally constructed, therefore it greatly resemble race. There is no real clear line to distinct the two.
In the past, races were identified by the imposition of discrete boundaries upon continuous and often discordant biological variation. The concept of race is therefore a historical construct and not one that provides either valid classification or an explanatory process. Popular everyday awareness of race is transmitted from generation to generation through cultural learning. Attributing race to an individual or a population amounts to applying a social and cultural label that lacks scientific consensus and supporting data. While anthropologists continue to study how and why humans vary biologically, it is apparent that human populations differ from one another much less than do populations in other species because we use our cultural, rather than our physical differences to aid us in adapting to various environments.
Although we often use race to classify, interact, and identify with various communities, there is a general consensus among scientists that racial differences do not exist. Indeed, biologists such as Joseph Graves state, "the measured amount of genetic variation in the human population is extremely small." Although we often ascribe genetics to the notion of race, there are no significant genetic differences between racial groups. Thus, there is no genetic basis for race. Our insistence and belief in the idea of race as biology, though, underlines the socially constructed nature of race. Racial groupings of people are based on perceived physical similarities (skin color, hair structure, physique, etc.), not genetic similarities. Nevertheless, we are inclined to equate physical similarities with genetics. Sociologists also use a temporality to argue that race is a social construct. The notion of race results from patterns from the signification of certain traits to different groups of people. However, these patterns (and societal notions of race) change over time. For example, the 20th century belief that "In vital capacity… the tendency of the Negro race has been downward" is certainly not commonplace among individuals today. Notions of race also differ across societies. Racial attitudes towards blacks, for example, are inherently different between the United States and Nigeria. These arguments all suggest that race is socially constructed. The lack of a universal notion of race means that it is not a natural, inherent, or scientific human trait. Rather, different societies use race to ordain their respective social
“‘And proclaim to the people the Hajj [pilgrimage]; they will come to you on foot and on every lean camel; they will come from every distant pass - That they may witness benefits for themselves and mention the name of Allah on known days over what He has provided for them of [sacrificial] animals. So eat of them and feed the miserable and poor. Then let them end their untidiness and fulfill their vows and perform Tawaf around the ancient House.’” (Quran 22:27-29)
If all men are created equal, then why should differences in race matter? Unfortunately our society has not lived up to the standards set by its forefathers.
Understanding other youth ministries mission statements, studying their programs, and exploring the positive and negative effects of the way that these ministries have chosen for their designs are important for effective leaders. This allots the opportunity to form ideas for one’s own ministry. Taken into consideration the location of one’s ministry and the group that one is reaching out to, a youth leader can form an effective youth ministry that is focused on youth on all levels of Christianity. There benefits to the ways those ministries were created in this study. There were also several limitations. It is a learning experience for one to study the different youth ministries and create a ministry unique to those whom they are ministering to in their own community.
Specific psychological characteristics are referred to as traits, and if you have any particular traits you belong to a personality type. In order to identify traits within individuals and differentiate them amongst themselves, the theories rely on personality tests, scales and inventories. The trait theory approach seems to be more realistic and objective. (Barker, R. and Wicker, A. 1975). However, the limitation lies in the fact that sometimes traits tend to be indefinable and vague, but personality tests are still widely used. With this theory consumers can finally be segmented into personality types, on the basis of the configuration of traits they
