All the living beings are believed to have developed over a period of time. Evolution process is the gradual change that changes living organism to a different form in order to adapt to the changes in the environment. The process of evolution is slow, and it describes why some animals exist while others become extinct. For example, the evolution process explains why the dinosaurs became extinct over millions of years ago. In order to understand the concept of evolution, we will look at the following key definitions and concepts.
Species is the smallest units of classification where the members Continue reading...

Controversy in the Nature-Nurture Debate

How much of the elements of genes and environment affect who we are? For over a hundred years, the influence of hereditary and environmental components in shaping ones’ personality has come under scrutiny by scholars around the world. Several researches are carried in pursuit for a valid insight of nature and nurture and its effect on human behavior. While most scholars today recognized the effect of both genes (nature) and the environment (nurture) in shaping ones’ personality, the debate rotates on how much of it affect ones’ intelligence and behavior.
In the nature-nurture study, nature is referred to as Continue reading...

Microevolution can be defined as a change in frequency of genes which can be observed over a period of time (normally a short period of time) within a single population due to different processes: mutation, gene flow, genetic drift and selection (either natural or artificial). Microevolution refers to smaller evolutionary changes within a single population in contrast with macroevolution which refers to evolution on a relatively large scale over a long period of time.
The four forces of evolution which bring about microevolution include mutation, genetic drift, selection (natural or artificial) and gene flow. Mutation refers to the changes Continue reading...

Abstract

Migraine is a complicated neurobiological syndrome that has been identified for quite a long time. A lot of studies exist on this subject matter. The main aspects of this disorder are throbbing and unilateral headache. It is commonly caused as a result of sensitivity to light and sound. It is considered as a vascular syndrome due to the pulsating aspect of the head. Nevertheless, the vascular alterations in the body do not fully support the pathophysiology of migraine symptoms. In fact, about 33% patients do not experience throbbing headache.
Migraine causes severe painful attacks of headache. As well, the Continue reading...

Genetics is the study of the genetic makeup of living organisms that determines how they behave. The genetic makeup is made up of genes that code for living organisms characteristic, and it is this biological code that determines who we are. Tapping into this information, according to researchers can be able to reveal so much about a person’s health and their well-being in the future.
The truth is that genetics dictates the health but a person’s behavior and environment, influence or attributes to a percentage of a person’s health. Some diseases are purely genetic like the Continue reading...

  I am Ali Ghajar. We are a group of 3 fourth year students from Calgary University taking a course in animal science. It has come to our knowledge that animal welfare in addition to how these animals are raised has become a great concern among the stakeholders especially the consumers in the livestock industry. This concerns touch on the health of the animal, housing, and maintenance of the normal biological functioning including production of these animals. Moreover, the animal welfare is threatened by variety of diseases such as mastitis which reduce production yield or cause of death to these Continue reading...

Evolution is one of the most important theories formulated by Charles Darwin in the year 1859, which affects the views of individuals on the relationship between humans and the natural world. The evolutionary theory explains about the transformation of species. Evolution exploits individual variations that are purposeless by eliminating those that confer no benefit to the organism. According to Darwin, the evolutionary theory accounts for change within the species and the emergence of new species in naturalistic terms. The study of genetics explains about the transmission of traits from parents to the offsprings, which helps to predict the chances Continue reading...

GMOs

Based on: UN/WHO, 20 Questions On Genetically Modified (Gm) Foods, http://www.who.int/foodsafety/publications/biotech/20questions/en/

How does WHO define genetically modified organisms? List any lingering questions or concerns about this definition.

Genetically modified organisms are those organisms whose genetic material has been artificially altered. This kind of change cannot occur naturally through mating nor through natural recombination but has been introduced into the organism through modern technology, sometimes called "recombinant DNA technology" or "genetic engineering". Concerns regarding this practice include the question whether this process is leading to the creation of new species and whether there are truly any real benefits from GMOs because they are generally not significantly cheaper, does not have increased shelf-life, nor better taste — concerns Continue reading...

The Preventative or Excessive

INTRODUCTION
Cancer is one the most feared medical diagnoses that any patient can receive. Granted we know a great deal more about cancer than in the past and many can be treated to a positive end, however, others are more risky. Breast cancer is a serious consideration for women. Today there are tests and measures that can be taken to identify, treat, and address the needs of breast cancer patients. Unfortunately, survival is still very much a matter of case by case basis. However, recent research has shown that there may be certain genes and hereditary markers that can Continue reading...

Aleppo (or Habab) is a city in Syria with a population of over 2,000,000 people. It is also one of the oldest cities that is still in operation in the world. It is estimated that Aleppo has existed 6,000 B.C. according to archeologists. Mentions of the ancient city has been uncovered on cuneiforms from Mesopotamia. The geographic location made it an important location in the Levant. For thousands of years it was mentioned as a strategic place for military and trade between Asia and the West. After the completion of the Suez Canal, the city began Continue reading...

One often hears the phrase “it runs in the blood” with reference to certain behavioral or physical characteristics. In the story “A pair of Tickets”, the author Any Tan tells the story of the author’s real life visit to her home land China. She claims that although she was not raised in China, the moment she set foot on Chinese soil she became Chinese. She says, "Once you are born Chinese, you cannot help but feel and think Chinese". These claims suggest that ethnicity is hereditary.
Inspired by the story “A Pair of Tickets”, this research proposes to Continue reading...

Altruistic behavior may be identified as behavior that puts an advantage over other individuals, not closely related while being obtrusively damaging to the individual doing the altruistic behavior (Trivers, 1971). Benefits and damaging effects are defined along the lines of inclusive fitness. A person, who goes into the water imposing an impending danger to save another distant relative from drowning, is a perfect illustration of altruistic behavior.
The altruistic behavior of an individual or an individual’s concern for another person’s fate increases because of genetic relatedness (Bernstein, 2005). However, according to Gintis, et. al's (2003), the recent Continue reading...

In the seminal collection of works known as the Analects, renowned Chinese scholar Confucius declared: “Men’s natures are like; it is their habits that carry them far apart” (Myers, 2008). Determining and assessing the extent that human characteristic traits and behaviors are governed by the environment and/or genetics is critical from a theoretical standpoint and view within the field of psychology. Humans indeed share an adaptive capacity that has emerged as a hallmark trait of fundamental human behaviors (Myers, 2008, p. 71). As such, basic, normative, and physical human traits such as having symmetrical two ears and two Continue reading...

Agriculture is at the heart of the progression of the human race as a distinct species, and our success can be measured directly to our advancements in terms of crop improvement. Agricultural biotechnology has been used to generate plants with novel traits, such as resistance to biotic and abiotic stresses, as well as pests. Plant biotechnology as a discipline entails both molecular plant breeding and the development of transgenic plants. Molecular plant breeding can be accomplished by selecting plants with desirable characteristics using complex molecular techniques such as marker assisted selection. Transgenic plants can be generated either via Agrobacterium-mediated Continue reading...

The quest for genetic perfection and biological immortality have obsessed scientists for eons of time. Technology and infrastructure are mere proofs of that. It is almost a primal need for man to strive for perfection, for example, in the genetic engineering whereby the idea of creating designer babies, building better athletes through gene doping and testing for traits unrelated to disease.
Human genetic engineering, for the major part, is ethical. No moral argument can refute the fact that testing for traits relating to diseases and eliminating them or finding ways to suppress them is necessary for the survival of Continue reading...

Neanderthals have been viewed by scientists for years as being unintelligent brutes, incapable of language and high level thought. Recent research in genetics has made important discoveries about Neanderthals. Geneticists are extracting DNA from the remains of Neanderthals and comparing it to the DNA of homo-sapiens and there have been some surprising discoveries. The process of decoding and analyzing the DNA had never been done before.
Scientists compared the genomes in Neanderthals genetic blueprint with the genetic make-up for five humans of different ethnicities. They discovered that Europeans and then Asians had more in common with Neanderthals than Africans. Continue reading...

Introduction

Addiction is a syndrome involving the reward-seeking behavior that can result in a significant harm to the person who is driven by an abnormal motivation process to regularly need or use something. It is often viewed as a psychological and physical compulsion of using habit forming substances, such as alcohol or drugs. Addiction is considered to be a complex disease affecting not only the individual’s health and well being, but also the people around the individual addict and the society at large. Hoffman and Froemke (2007) describe addiction as a chronic disease of the brain, as a disease, Continue reading...
