Download file to see previous pages Although the megafaunal extinction occurred in different places around the world, it is not possible that this event was the first global change associated with people because of the fact that scientists have estimated that the human beings came from the chimpanzees back between 5 to 7 million years ago even before the Homo erectus in Asia and Homo neanderthalensis in Europe has evolved and became extinct (McHenry, 2009, p. 265; Stringer, 1994, p. 242). Several publications revealed that the Homo sapiens themselves practiced globalization by simply migrating out of Africa heading towards the different parts of the world (Gills & Thompson, 2006, p. 8; Brown & Siegel, 2005). Considering the possibility that the Homo sapiens left Africa around 195,000 years ago (Brown & Siegel, 2005), it is clear that globalization existed even before the megafaunal extinction occurred in the United States, Europe, and Australia. Over the next few years, major economic changes that are now happening in the agricultural production can eventually become the basis of the future anthropogenic global change. As a common knowledge, globalization is about maximizing the use of the available human and natural resources with the least possible cost. In line with this, agricultural activities within the developed countries are likely to become less attractive in the global market because of the high labor and operational costs. Instead of purchasing agricultural products from developed countries, many people around the world would end up purchasing agricultural products from developing or underdeveloped countries because of quality and price-related issues. Because of the sudden increase in low-cost agricultural products in developing and underdeveloped countries, many people who are currently living in rural places will be encouraged to engage themselves in agriculture-related businesses. ...Download file to see next pagesRead More

Evolution in Education over the 75 Years

...? Evolution in Education over the 75 Years How has education changed over the past 75 years in terms of s taught, discipline and the college expectations? If the quality, quantity, nature and the scope of education are analyzed over the course of the past 75 years, a pattern of change and evolution can be traced out. In an effort to compare and contrast different eras in the context of education, certain prototypes can be drawn in terms of continuity and change. However, change is the predominant theme emerging as the patterns of continuity are very minor even if present. Therefore, in this regard it is important to scrutinize the eras, i.e. the 1920s, the 1950s and the 1980s with reference to the developments regarding education... . The...

The Four Forces of Evolution

... The Four Forces of Evolution Change and evolution are two different terms. A person may change but may not evolvewhile the whole population may change and evolve into a new society. Changes are part of any individual’s lives but when the changes seems to be adopted by the whole population and completely transformed its whole entities, this is called evolution. To help us understand evolution within a specie or population level, let us define first species and population. According to Haviland, Prins, Walrath and McBride, species are the smallest working units in the system of classification and are composed of populations which are capable of interbreeding and producing viable offspring; population, on the other hand, is a group... .

The Bottom Billion

...projects and sending troops to put down rebellions. Collier’s findings have overturned the persistent myths about the failure that Africa is facing for decades. He finds that the history of failure and civil wars is not because of the poor politicians or restless populace, but because of poverty. So he states that all countries that are poor and low income face about 14 per cent chances of entering in a civil war during a five year period. Collier writes that the young men who are recruited by the rebel armies are cheap in an environment of immense poverty. Hence, joining the rebel movements give these young men a minor chance of riches (Collier 57). The four poverty traps described in the book includes...

Explosions on a Sun 70 Billion Light Years from Earth

...and curves are rendered to flow in several directions attributing how ‘explosion’ at the face of the sun may be imagined with intensity and violent motion. “Explosions on a Sun 70 Billion Light Years from Earth” is evidently filled with not only the dynamic curves heavily dotted at the core which altogether seem to be an abstract view but even with rich colors illustrating the sun’s nature. A mix of red, orange, blue, yellow, and green in varying degree throughout the piece understandably indicates the evolution of gases, collapse of cosmic bodies, and other interstellar reactions in space at the occurrence of explosion. Looking through the heart of the dots, it feels that the painting...

First of all you write a sentence which is of more than 8 characters. Then you remove the space between the words. Once you remove the space you can intentionally misspell a word in order to make it complicated. The only thing that you should keep in mind is about the way in which the word is misspelled. Later you can add numbers or symbols into it and make it lengthy and complicated.

Four Forces of Evolution

...Four Forces of Evolution Evolution is a process that contains four forces and these four forces include: genetic drift, natural selection, gene flow and mutation (Fogiel 908). Mutation being one of the forces of evolution takes place when changes in DNA or De-ox ribonucleic sequence of a certain genome of a cell takes place. When mutation arises, it results in alteration of the entire gene product or it can even result in prevention of the normal way in which a gene functions and it may even have no impact at all. These changes vary from population to population. Variations that may occur as a result of mutation include change in...

Microevolution: This describes the significant changes that occur in a species over time, to give it traits or groups of traits classifying it differently from its original species, for example, as a sub-species, a variety or a race (Maiti & Maiti 252). Macroevolution: This describes the significant changes in a species over time that makes it into a totally different species. An example is the evolution of earlier tetrapods into mammals. The results of this process are cumulative that is, the species form after an evolution for over millions of years (Maiti & Maiti 254). There are the four forces of evolution; Mutation: Mutation...

Four forces of evolution

...Four Forces of Evolution Evolution is a process that is associated with change in gene allele with time. Four primary mechanisms successfully explain the evolution process: natural selection, mutation, gene drift, and gene flow. All these forces contributed significantly to the evolution process. In connection with this, the paper aims at expounding the role played by each force to the evolution process. The world is believed to have contained a small population before the start of the evolution process. As time passed, accidental change in gene allele of the species in the small population took place...

The Four Forces of Evolution

...Four Forces of Evolution Evolution is defined as a process that involves the change of alleles that make up genes in an organism. The process of evolution is well defined by four primary sources; gene flow, gene drift, natural selection as well as mutation. In tandem with this assertion, the paper will provide detailed information on the four forces, and they are involved in the evolution process. Majority of the biologists believe that the world started as a single unit with a small population of primitive organisms. The environmental conditions however continued to change with time leading to accidental changes in the...
