Introduction

Evolution is the alteration of nheritable traits of the biological populations over a series of generations. In biology, it means to observed organism’s changes, to the descent of a common ancestor and at a technical level to a gene frequency change over time. The processes lead to diversity over a large biological organization, including the molecular evolution’s level, individual organisms and the level of species (Gregory 2009). Each and every life on Earth originated from a common descent from a last universal ancestor, whose time of existence is approximated at 3.5-3.8 billion years ago. Repeated creation of Continue reading...

Why We Get Sick

Chapter 6. Toxins, New, Old, and Everywhere
There are lots of novel toxic hazards to which we are exposed. There is alcohol, agricultural pests, nitrates, toxic dust and fumes, spray insecticides that enormously harm our health day by day. It seems obvious that our modern age must be more hazardous than that one our ancestors lived in. But this is not true because the contest between consumer and consumed can generate an evolutionary arms race.
Most plants contain toxins that would be harmful if eaten in more that a minimal amount. These toxins keep herbivores from eating the plants Continue reading...

Background to the Problem

The ongoing dispute about the origins of the planet and every living and non-living thing in it has had a long history. In this dispute, we have the theories of evolution on the one hand and creationism on the other. In this research, we try to propose a study that investigates the different facets of the evolutionary theories and also that of creationism to shed light on some of the most common and perhaps longest controversies in an area where there is an overlapping of numerous fields such as philosophy, theology, biology, and other areas of science. The objective Continue reading...

Introduction

What is evolution?
It is a gradual or a slow process in which organisms change into a different form and mostly the new for is better than the old one. As the organisms respond to changes of environment, they develop features that will enable them survive in the new environment and thus evolving.

In the evolution, we have four forces of evolution, and they are as follows:

1. Mutation; this is by which the genes or chromosome change heritable. The random variation of the genes is due to additions, deletions or substitutions of the nitrogen bases of the DNA sequence.
2. Gene flow; this is whereby two populations exchange their genetic materials; it Continue reading...

What chemicals do Nitrosococcus oceani and Nitrosopumilus maritimus consume from their ocean environment?  How does the abundance of these chemicals influence their success and abundance?  What is the relationship between nutrient availability and natural selection, in general?
Nitrosococcus oceani and Nitrosopumilus maritimus are examples of single celled organisms which are part of the kingdom Archaea. They are totally separated from the bacteria and other organisms (Stewart, n.d.). They are very important for some of the natural processes in the environment especially for the nitrogen and methane cycle. They are also a major part of the biological and biomass processes Continue reading...

The theory of evolution has received much attention by the clergy and the scientific community alike ever since Charles Darwin proposed it. It was proposed in order to explain the source of variation among different organisms as well as explain the possible beginning of life on earth. There have been diverse debates on this theory and the people from all walks of life are divided in perspective due to it. In order to make a clear and strong stand about evolution – whether it is valid or not – it is expedient that several concepts relating to it be understood. All Continue reading...

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...

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...

The evolution of the peppered moth can be dates to around 200 years back which was a consequence of the industrial revolution. The evolution was based on the colour variation between the two species. The evolution was based on the concept with the increase in the number of dark-coloured moths as a result of industrial pollution. The rapid increase in these species led to the decrease in the original species in the environment. Thus, the phenomenon is known as industrial melanism. This was the first case of natural selection which was mentioned by Charles Darwin. The peppered moth is Continue reading...

Humans are curious beings. There is always a need to know more – to understand more about the world we live in. Scholars, researchers, scientists have long been proven to exert efforts in meaning-making and information dissemination. However, the scientific community will always be in conflict with the Church. Still, the efforts do not dwindle. Prominent scientists have changed the ways of thinking of the primitive society. One of these scientists is Charles Darwin.
Charles Darwin is a British scientist and the Father of Evolution and Natural Selection. Initially, he took up medicine at Edinburgh University, and then studied divinity Continue reading...

Analysis of a specific behavior

Genus & species: Canis and Lupus
The specific behavior (describe): Barking is a normal and natural behavior used by dogs for communication purposes.
Is this behavior shown only in certain behavioral contexts, such as in communication, getting food, competition, social behavior, attracting mates, mating behavior, parental behavior, or some other area of activity?

Barking is mostly used by dogs for communication.

Is this behavior stereotypic of the species? (I.e. typically by all similar members of the species, similar by sex or age or reproductive status.)

Barking is a behavior stereotypic of the species.

Science provides some cues as to how humans ought to behave. According to the evolution theory suggested by Darwin, natural selection affects all the creatures on earth (Futuyma, 2009). In this case, humans, just as all other living things seek to compete for space, wealth, and any other means of survival. Even though the modern man has changed the environment greatly, the inherent competition depicted in the evolution of mankind has not stopped. The rich seek to be richer while the poor seeks to liberate themselves from poverty. However, it’s worth noting that in as much as the 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...

Strategic Innovation
1. INTRODUCTION
Success in present, global market conditions require much more agility and responsiveness to client needs. As organizational structures of global companies respond more swiftly to market conditions and client needs, conventional management practices become not only irrelevant but also constitute serious challenges to any strategic advantage a company could attain in a highly competitive market (Baden-Fuller, 2005). Further, a significant feature in organizational structure is emerging in company management which has redefined how internal Continue reading...

It is known that in the summer of 1842, Charles Darwin finally decided that he had collected enough material on the problem of the origin of species to make his views as a small sketch. There was the overall structure of his theory presented. Two years later, Darwin wrote an extended version (an essay), which, according to his instructions, was to be published in the case of his death, if he did not have time to write something new on this topic.
Darwin could publish that essay immediately but he decided to spend eight years (1846-1854) addressing the morphological Continue reading...

In 1859, Charles Darwin published his seminal work On the Origin of Species in which he expounded on the theory of natural selection, which catalyzed a paradigm shift in how human beings perceived world history vis-à-vis the concept of evolution. Darwin introduced into the intellectual and scientific milieu of the nineteenth century an important component that played a direct role in western imperialism (Bentley and Ziegler 550). At the crux of Darwin’s argument was that through empirical observations in diverse locales throughout the world studies of flora and fauna, those that are best adapted to changing circumstances Continue reading...

Give a specific example to explain how principles of classical conditioning are used by advertisers to sell products. Be sure to include terms discussed in class.
Advertisers used plenty of ways to motivate consumers to purchase the product they are endorsing. One of this ways is through the process of classical conditioning initially introduced by Ivan Pavlov. A perfect example for this is the New York Bestseller book entitled 50 Shades of Grey. This has become an instant hit. In fact, the book has sold millions of copies worldwide. To explain the favorable feedback of the consumer to the Continue reading...

Origins of the lack of empathy

The lack of empathy or psychopathy is a disorder that is most prevalent in the society and is common in prison inmates. Furthermore, one can conclude that an individual with tendencies of violence tends to have psychopathic traits. Psychopathy can be linked to both genes and the environmental surrounding. According to Patrick (2005), some genes have been investigated to be the reason why individuals become psychopaths. Some of the character traits of psychopaths such as manipulation, early reproduction have been linked to the Darwinians natural selection theory survival for the fittest. Using the natural selection perspective one can conclude Continue reading...

In my opinion, “Margin Call” can be discussed from three perspectives, which are economic, biological and psychological. The film is considered to be a drama and a thriller at the same time. The economic problem depicted in the film is quite obvious and the audience does not require a degree in Economics or Finance in order to understand this. However, the economic component is this movie plays a role which is way too far from being vital, or even one of the key points. As a person watches the movie further, it becomes obvious that human nature, behavior and Continue reading...
