Human Evolution Human Evolution‚ the biological and cultural development of the species Homo sapiens‚ or human beings. A large number of fossil bones and teeth have been found at various places throughout Africa‚ Europe‚ and Asia. Tools of stone‚ bone‚ and wood‚ as well as fire hearths‚ campsites‚ and burials‚ also have been discovered and excavated. As a result of these discoveries‚ a picture of human evolution during the past 4 to 5 million years has emerged. Human Physical Traits Humans are

COMPUTERS The evolution of electronic computers over a period of time can be traced effectively dividing this period into various generations. Each generation is characterized by a major technological development that fundamentally changed the way computers operated. These helped to develop smaller‚ cheaper‚ powerful‚ efficient and reliable devices. Today‚ life has become indispensable without a computer. You find computerization in almost every sphere and industry. Computer evolution has been a fascinating

Color in film went through a self-contained evolution much like sound. Many films of the silent era‚ for instance‚ used processes such as tinting and toning to give an overall color to the frame (Thomspon & Bordwell 34). Thompson and Bordwell comment on the process that “color could provide information about the narrative situation and hence make the story clearer to the spectator” (34)‚ much like the use of photogénie and mise-en-scene by the Impressionists and Expressionists. Other films‚ such

Evolutionary Concepts Defining Speciation: BSC and Recognition concept Species are produced by individual speciation events‚ so a single species concept can’t be defining all species. Hugh Paterson’s ideas are significant in understanding evolution. Paterson argues that speciation is not an adaptive process‚ but is a result of the adaptation of intricate bonding mechanisms to a new environment (Paterson). The conceptual basis of his research is the Recognition Concept of Species. He argues that

2014 Human Evolution The Evolutionary History of Life on earth traces the process by which living and fossil organisms have evolved since life on the planet first originated until the present day. According to research earth formed about 4.5 Ga (billion years) ago and life appeared on its surface within 1 billion years. The similarities between all present day organizes indicate the presence of a common ancestor from which all known species have diverged through the process of evolution. Every

Over time‚ many theories have been developed concerning the way evolution was originated. One of these main theories was that Multicellular organisms originated slowly over the last billion years from unicellular organisms. Another main theory is that Multicellular organisms originated abruptly during the Cambrian (around 500 million years ago) explosion from unicellular organisms. While these two theories are very different from one another‚ many people support each of these ideas. However‚ I am

As a species continues to reproduce over long periods of time‚ they being to change physically‚ otherwise known as evolution. Evolution is a theory in which organisms change over time and become either better or more complex. ( 1 ) Charles Darwin‚ the Father of the Theory of Evolution‚ discovered that similar birds had adopted different beaks (finches 2 ). And thus‚ the theory of evolution‚ already placed in Darwins head by his grandfather‚ ( 3 ) had been further proven. The French biologist JeanBaptiste Lamarck

In 1776 the thirteen colonies adopted the Articles of Confederation in order to coordinate their efforts in the war for independence. The Articles of Confederation bound the states together in two main aspects; foreign and military affairs. The Articles of Confederation worked well while all the states had a common cause. However‚ as soon as the war ended and interests began to change‚ it became obvious
