Life forms adapted to the environmental changes that have taken place over the years to evolve to diverse life forms that are present in planet earth today. The various processes that ensure adaptation of the life forms include evolutions and mutations. There are various environmental factors that have contributed to the evolution of the organisms. All the life forms depend on the environment to obtain the nutrients required for survival. Therefore all life forms have to match up with the environmental changes and this is referred to as adaptation.
There are various environmental changes which have occurred over the years such as changes in climate and seasons, competition, occurrence of infectious diseases and predation. In order to survive with these changes in the environment, the life forms have to change over time in a process referred to as evolution. Since nature is more of cooperative rather than competitive, all the life forms tend to evolve together in a process known as co-evolution in ordre to fit in and not become extinct. The various life forms cooperate in that some provide nutrients and shelter to others and competition only comes in when the organisms obtain their nutrients from the same source.
Mutation is also another factor that has led to the adaptation of the life forms to the environmental changes over time. The process of mutation takes place in reproduction whereby the genetic makeup of the parent is passed on to the offspring. This process is inevitable and naturally occurring and can result to the production of an offspring that is better or worse adapted to the environment. This leads to survival for the fittest whereby only the best suited are able to survive to the reproduction age and the other organisms die before reaching that age. This serves to ensure that all the offsprings produced by have the mutations which enables the life...

Comparing Ltdr

...Comparing ‘Love That Doth Reign and Live within My Thought’ with the Unseen - Dr. Helen Fisher’s ideas about love The poem ‘Love That Doth Reign and Live within My Thought’ was written by Henry Howard, the son of the Duke of Norfolk who was executed for treason at the age of 30. It deals with themes of confusion of love, love itself, and death. He talks about a man being in love with a woman who does not return his feelings, this is also known as ‘courtly love’ and Henry was one of the first to introduce unrequited love as a main subject in the 16th century. The form of this poem is in a Shakespearean sonnet made up of 14 lines (3 quatrains followed by a final rhyming couplet) and is a translation of a Petrarchan sonnet. It follows the rhyme scheme ‘abab, cdcd’ and so forth, and uses inverted feet – this portrays the poem as quite masculine. Because this poem was written so long ago, there is a lot of archaic lexis and sophisticated language for example: ‘ire’ and ‘eke’ thus immediately showing the reader the time period that this poem was written in. The narrative stance of this poem is in 1st person, but mainly in the 3rd person – describing a knight. The unseen text is written by a biological anthropologist named Helen Fisher, straight away this makes it apparent to the reader that this is a more analytical and scientific view of love. Both texts talk about love, however she talks more about lust and intimacy. In paragraph one she supports love and talks about the......

...In modern politics, a state is an association which has control over a geographic area or territory. States are seen as having three main pieces: * A territory * A people * Some institutions (which have the power to make rules). There are different forms of government a state can have, for example a republic or a monarchy. Sometimes states form their own countries. At other times many states work together to form a country (like the United States). Most states also have armed forces, civil service, law and police. Politics is the way that people living in groups make decisions. Politics is about making agreements between people so that they can live together in groups such astribes, cities, or countries. In large groups, such as countries, some people may spend a lot of their time making such agreements. These people are calledpoliticians. Politicians, and sometimes other people, may get together to form a government. The study of politics in universities is called political science, political studies, or public administration. In everyday life, the term "politics" refers to the way that countries are governed, and to the ways that governments make rules and laws. But politics can also be seen in other groups, too, such as in big companies, schools and churches.

The Evolution of the Hero

...Hum I: Philos. Thought (HUM-101-OL010) Written Assignment 2 18 May 2013 The Evolution of the Hero Heroes are part of every culture’s mythology and the most famous and diverse is that of ancient Greece. In order for us to assess the development of the Heroic ideal in ancient Greek culture, we must be able to identify where the Hero’s identity comes from. The Heroic identity has been useful for thousands of years, serving as a perfect representation of a super-human, a human that is capable of dealing with problems that require unique skills and knowledge beyond that of a normal person. But where does it come from? The answer is simple. A Hero’s identity has its roots in the culture it lives in. That is to say, the Hero’s identity is a direct reflection and embodiment of the values and ideals of its society. The Hero is society’s way of reproducing its values and beliefs for the next generation. As a result, the characteristics that make up a Hero are as varied and different as the cultures that created them. When examining the evolution of Heroic ideals, one must be aware of the always changing cultural conditions and the necessity of the Hero’s criterion to fit an ever evolving society. If you look at Homer’s The Illiad, his portrayal of a Hero is someone who is famous, has great strength, kills many people and governs strongly. The Homeric Hero must obey all of society’s customs and religious rituals, and if threatened, was......

Evil Deeds

...evil, is only done out of ignorance and not from the intention to do evil. This view appears controversial because people are known to occasionally commit deeds that are apparently evil either out of self-interest or acting on impulse, against their better judgment. It is at this point that we come to an important clarification. Socrates did not state that doing wrong to others is ever right, but that the motivation for such actions determines the character of the will involve. Socrates maintained that people are never motivated to bring harm to themselves. Since Socrates believed that wrongdoing always harmed the wrongdoer, he saw all wrongdoing as a mistake in judgment or an expression of ignorance. This is especially true in cases where a life full of wrongdoing never physically harms the wrongdoer. Socrates believed that the most pitiable of humans were those who lived under the delusion that their wrongdoing benefited them. Socrates saw no conflict between self-interest and morality. On the contrary, he saw virtue as the greatest benefit and maintained that immoral actions actually harmed the agent and could therefore only be committed out of ignorance and misunderstanding of what the greatest benefit is. The aim of this essay is to demonstrate how it is possible that nobody does wrong knowingly. Also, objections to this argument will also be discussed. This will show the other side of the story in addition to possible rebuttals by Socrates. In his first premise......

Plato Essay

...was an Ancient Greek Philosopher who was taught by Socrates. Plato believed the world we live in a world of appearances, however he also believed that there is a world beyond, one containing forms which was the world of ideas which he the world of the forms. Forms are the general realities or ideals versions of something. Forms in Plato’s eyes where perfect versions of something, and in the world of the appearances they are many particulars which have copies or impact versions which imitate the perfect version of the form. The world of the forms is an epistemology which can only be used by tapping into the intelligible world without using your senses. For example in the world appearances they are many types of cats but in the world of the forms there is only one perfect version of that cat. Plato’s analogy of the cave is a way to interpret Plato theory of the forms and his idea about the universe. Plato’s analogy begins with the prisoners sat in the cave, chained together, and facing a wall preventing them to see or to gain any movement: a fire blazes behind them and on the other side of a passage way. Along the pass way men carrying statues and talking casting shadows on the wall which the prisoners face which made the prisoners it is a puppet because that is all they have seen all their life. When a prisoner escapes the cave, he realises that the shadows casted are real people and that they is another world with a sun outside which at first he is blinded by. When he returns......

...Explain Plato’s analogy of the cave. Plato, a famous Greek philosopher who wrote the ‘Allegory of the cave’ attempted to answer some philosophical questions (Why are we here? What is reality?). Plato tells the ‘Allegory of the Cave’ as a conversation between him and his teacher, Socrates, who inspired may of Plato’s philosophical theories. The Analogy of the cave is one of the most famous passages in Plato’s republic. Imagine prisoners being chained up in a cave, since their childhood. Theses prisoners are chained up and forced to look at the wall in the cave. The only source of light in the cave comes from a fire. Behind these prisoners is the fire and between them is a raised walkway, which allows people to walk through the cave. As the people walk through the cave their shadows are reflected onto the wall and their voices are cast as echoes. The prisoners assume that the echoes come from the shadows cast on the wall. This makes that prisoners believe that the shadows on the wall are real, because they are unable to see what is really happening. This means that the prisoners are unable to see the true causes of the shadows, as they are unable to see behind them. Suppose one of the prisoners is finally freed. This prisoner is forced into the real world; he feels confused and doesn’t understand what is going on. He naturally wants to go back to his familiar surroundings of the cave, if the prisoner is prevented from going back to the cave. Gradually his eyes become......

You cannot find perfection since perfection is only found in the abstract form of justice. • The ideal of the early Greeks was the perfect male model like hipieus. • Socrates tells hipieus and asks him what beauty is? • Hipieus answers that beauty is a beautiful woman... he thinks that this is obvious • But Socrates continues to challenge him that beauty is not just related to...

Plato's Theory of the Forms Is Unconvincing

...Theory of the Forms is also seen as unconvincing as it is highly abstract. Therefore it is too incomprehensible to see the way in which these detached Forms can be practical or have significance in the real world as they are too distant. Even if they do exist, do they have a practical function? Can they help humans make decisions about practical matters? In addition very few people will obtain knowledge of the good therefore can the Forms realistically be understood and accepted by all? In this way the Theory is not convincing as it leaves many basic questions unanswered. We are also to question whether there are Forms for everything, from a stone to a lampshade. Plato rarely discusses physical and material objects but more Forms of concepts such as Justice. While he does mention the Form of a bed in The Republic, we are uncertain as to whether this was a serious remark, some even think it was a joke. Furthermore Plato does not clearly explain the link between the World of Forms and that of Appearances, how do they connect? Furthermore we question how general the Forms are. Is there a Form for every breed of horse or just a general Form of a horse? If a Form is a general idea then there is a risk that it lacks detail. However if every breed has a Form then surely the Form loses it's point. One could argue that every breed of horse has enough in common to reflect to some extent the Form of a horse. Again this may not be an issue for Plato if the Theory of Forms applies......
