...Biology Essays 1. The human population reached a new milestone on Oct 31, 2011. How does this impact evolution? Include climate change as one aspect of your response. (Think about Darwin's observations which led him to Natural Selection.) -The first sentence of this question refers to our human population reaching to about 7 billion people. To my knowledge the earth can hold that many people, but on the other hand, if our human population keeps growing, I think that then nature will select (according to Darwin’s observations) due to over-reproduction and our resources being limited. When natural selection comes along there will be a lot of competition, suffering and death so that there can be room for our upcoming population. Climate change can impact the evolution in many ways because of weather intensity such as; droughts, flooding, harsh snow, heat waves and emerging disease that can occur throughout the change which can decrease our human population (death). 3. Explain which parts of evolution are random and which are not random. -According to my notes, evolution is a process, but not a random process. It’s certain things that makes it random. Natural selection is one of those things to make parts of it random. Evolution is determined by ancestors, traits inherited and also what genes are passed. 4. Explain why pseudo genes accumulate mutations more regularly than functional genes. (Include natural selection in your response.) -Pseudogenes accumulating mutations is basically...

...modern day are not like the use to be back in the days. Everything about them are evolving from lame to the point now you can barely notice them from any other person. They’re just trying to fit in just like any other subculture now days. Nerds are not the same now how they were back then. Everyone calls this subculture by many names mostly Nerds or Geeks. What about the nerds and geeks of the world? Where is their infographic, when will nerds feel safe to leave their studies and work alone and try to live a little? When will geeks leave their parents’ basements and shout they are people too? How about our friends, will they ever stand up straight and be heard or will they be left behind the group of cool kids, plotting their revenge? Infrographics Guy commented “Aw, who cares, geeks and nerds rule or will rule the world when they get older so bow to them now while you still have a chance.” Yes, Nerds are still unpopular but they are coming up in the world. No longer are they basic people with button downs, glasses, and suspenders. The term “nerd” goes back as far as I can remember. The term is not something they like to claim but it’s just a gift that certain humans were born with. Everything about them is evolving, nerds do not dress the same anymore or do they act the same. Nerds are literally smart people and it’s a big correlation in the two. Being smart seems to make you unpopular. Why? To someone in school now, that may seem an odd question to ask. The mere fact is so...

...Are Modern Humans Still Evolving?In the year eighteen fifty-nine, Charles Darwin published a book which he called “The Origin of Species”. In this book Darwin theorized that populations evolve over the years through a process called natural selection. Darwin realized that in a population, more individuals were born than could possibly survive, he also recognized that the individuals that survived and reproduced were the ones with some sort of competitive advantage over rival animals, therefore they were more likely to pass their useful traits down to their offspring (Darwin, 1859). As this process of natural selection occurred for millions of years, these desirable traits that were once only prevalent in a few individual animals became common traits for entire species (Winston, 2009). There are countless amounts of evidence that suggest that humans owe their existence to evolution, however, many people are skeptical as to whether or not it is still occurring, and whether or not it is happening in the same way. Some scientists hold that the human race has reached “its biological pinnacle and is no longer capable of changing” (McKie, 2005, ¶1). Alternatively, some experts believe that humans are evolving faster than ever (Sample, 2007), and others believe it is still happening, just on different terms. There has not been any deciding evidence as to whether or not humans are still evolving, however, saying it isn’t happening is a very difficult position to defend. Gene mutations...

...Gay rights has a major impact on today’s society whether we choose to believe it or not; for or against. Gay rights are becoming one of the more controversial topics being discussed around the America today. Gay rights should be recognized, there are many factors of gay rights that Americans do not completely understand, while times are changing gay rights is evolving from state to state there are still issues yet to be resolved. Today I will discuss three key topics when it comes to gay rights; gay rights in schools, arguments for and against gay, rights and gay rights in adoption. Gay rights has been a controversial topic for quite some time now; in public schools all over north America that last couple decades gay rights has been opened up and discussed. Openly gay students are coming together in a safe haven, where without judgment they can come together and support each other with any difficulties they may be facing. “Gay-straight alliances are a form of social support for lesbian, gay, bisexual, transgender, and questioning (LGBTQ) high-school students that emerged in the late 1980s and early 1990s. These alliances are generally student-run social clubs akin to other high-school social groups, such as drama clubs, math teams, or yearbook clubs. However, one of the main purposes of gay-straight alliances is to provide support to LGBTQ students in difficult personal circumstances or in hostile school environments, and to advocate for LGBTQ students,” (Fetner, T...

...differentiate between the humanities and other modes of human inquiry and expression. I shall list types of humanities and explain why each one gives reflects current developments in politics, socioeconomics, and technology. Colorado State University defines humanities as, “The branches of learning (such as philosophy or languages) that investigate human constructs and concerns, as opposed to natural processes. The humanities, such as classical and modern languages, literature, history, and philosophy, have the overall goal of the exploration and explanation of human experience.” Art has long been a means of expressing social or political ideas. Anselm Kiefer took art and brought it to an entirely new level by using his art to bring attention to national identity and collective memory. In the process his art began evolving to include occult symbolism, theology, and mysticism. All of his work shares a common theme of the trauma experienced by entire societies and the continual rebirth and renewal in life. Music defines periods of history as well as generations. It evolves with societies/cultures and tends to give people their identity. Music has a strong connection through celebration, remembrance, expression of emotions, and ministering to others. It allows the human race to connect to their own humanity not only as individuals, but as a collective society. Music has been a way of human expression since the beginning of time. It is argued...

...On November 24, 1974, Lucy was discovered. Lucy is the name given to the 40% discovered skeleton of a hominid that lived about 3 million years ago. Lucy's skeleton included an ape-like skull and bones for habitual bipedalism (a type of transportation/movement used by humans). Other animals do use bipedalism to perform certain tasks but only humans and birds are known to have used it for movement. The discovery of Lucy was perfect evidence for the theory of evolution. This theory answers why life changes and why so much diversity exists. All organisms have developed into their current form by evolving from their ancestors forms. In the Origin of Species, Charles Darwin (a well-known philosopher), mentions, "that each species had not been...

...survive the environment we are in our daily lives and reproduce offspring. This is called natural selection, which is now considered as the main process that brings about evolution. Now, the real question is, are the natural selection process still existing today and are we still evolving into another species? First of all, humans did not evolve from monkeys. Humans share a common ancestor with modern African apes (similar gorillas and chimpanzees). Scientists believe that this human related ancestor existed 5 to 8 million years ago. There after, these ancestor species were separated into two separate ancestries. One of these ancestries evolved into gorillas and chimpanzees and the other evolved into early human ancestors called Hominids. In other words, these common ancestors that separated over time, formed a number of distinctive species of hominid. Only one of the hominid species survived to become modern humans that we are today. Natural selection led the surviving species (hominids) into evolutionary change. The surviving species had certain characteristics to have greater survival than other species in a population and pass these transferrable genetic characteristic to their off spring. The rest of the hominids, including early humans, became extinct. They became extinct because they were...

...Patterns of Evolution Dawn Austin SCI/230 January 28, 2011 Mrs. Sara Young Humans shape their environment in ways that other organisms cannot. Are humans subject to the same pressures of natural selection as other organisms? Why or why not? Yes, Humans are subject to the same pressures of natural selection like all other organisms. According to an article I was reading, the fact is that change in gene pool over time in all species is completely avoidable. Eyre-Walker and Keightley claimed that in 1999 that humans have had an average 4.2 amino acid altering mutations every generation since humans separated from the chimpanzees (physicpost.com, 2003). Provide an example of convergent and divergent evolution, adaptive radiation, and co-evolution. Adaptation radiation is an example of divergent evolution. Divergent evolution is the process of two or more related species becoming more dissimilar. An example of divergent evolution is; the red fox and kit fox, the red fox lives in forest and farm lands where its red color helps it blend in with surrounding trees. The kit fox lives in the plains and in the desert where their environment is sandy and their color help conceal them from prey and predators. The ears of the kit fox are larger from the red fox. The kit fox ears are an adaptation to its desert environment. The enlarged surface area of its ears help the fox get rid of excess body heat. The red fox and the kit fox have similarities that suggest that they had common...

...to take the human out of the loop? From the beginning of the world humans always wanted to make their life easier. They produced more and more complicated tools for hunting, then for harvesting and other branches of human activity – these tools allowed them to make their job without using their bare hands. Time was passing, humanity was evolving newer technologies, people knew more and more about the world and laws that rule it. But one thing that every human-being wanted the most was faster way of travelling. The first step was inviting wheel. Later humans built carts, coaches and many other vehicles propelled with animal’s or person’s strength. But still it was too slow and too less automatic for people. The change came in 1769, when Nicolas-Joseph Cugnot presented his steam vehicle. Then everything started to evolve faster – and we step to nowadays, where we have many different types of cars, even the ones fueled by water or electricity. In our century, where artificial intelligence isn’t a Sci-Fi subject only but also reality, people started to think about using it in car’s safety and driving system’s development. One of the results is Google’s self-driving car, which is travelling in states of Nevada, Florida and California, where autonomous vehicles are already legalized. This technology is evolving all the time and maybe there will come the day where whole world will be able to use such kind of cars. But there comes the question – is it safe to take the human out of the...

...Patterns of Evolution When it comes to natural selection there is pressure for all organisms that have reproduction. I just don’t think there is that much for humans because of the advantages that we have, such as brain functions which helps invent items for everyday living in different types of environments. Having a population with differences among the herd, there would be conflict on who fits better with the habitat and who doesn’t. For example, that is why there is so much prejudice, racism, war, and killings going on in the human environment. Just like in some animal species, if one of them doesn’t fit into their pack or have a deformity, they will more than likely kill them. The process of unrelated organisms evolving to become similar in appearances and behavior is known as convergent evolution. An example of these would be rodents that are distant relatives that live in the dessert. In divergent evolution closely related species living in different environments and facing different environmental challenges sometimes evolve dissimilar characteristics. Some of these bones make up human arms, dog limbs, horse legs, and bat wings. They all have the same origin, but all have very different morphology and very different uses. Adaptive radiation is where a number of species evolved from a single ancestral species. Honeycreeper which is a breed of birds found off the Hawaiian Islands is a great example of adaptive radiation. Then there is co-evolution which is the process...

...GAY MARRIAGE SPEECH Intro * Society is evolving – We elected our first black President, in fact, a woman was even a real Presidential contender as well – the traditional roles of the working family do not look so traditional anymore * I am going to discuss the subject of gay marriage – while we as a society have made great strides we are still far from an acceptable solution * Whether you believe in same-sex marriage or not, I ask that you keep your mind open and listen to my points. I will give a few of many reasons why I believe it is finally time for us as Americans, as humans, to allow everyone, include those from our gay community, to experience the same joys of marriage that the rest of society enjoys. 1. We do not want to discriminate a. America was founded on the concept that the majority should rule, but the rights of minorities should be protected. b. It is the main reason we have a Bill of Rights as well as anti-slavery and equal protection amendments. c. Denying marriage to a homosexual couple is no different than denying marriage to a Hispanic or African-American couple 2. Reasons why gay marriage is beneficial a. In a religious marriage two people promise to take care of each other profoundly the way they believe God cares for them. b. This religious union will encourage people to have strong family values c. It will discourage high-risk sexual life-styles d. In essence, recognizing this union will counter act...

...The Human Resource department is an integral part of any organization and their roles have changed in many different ways over the years. No longer are they considered only the aspect of the company that handles all of the hiring and firing of personnel, they are now deeply rooted in the overall goal of the firm and its employees. Today I will discuss important roles of human resources (with personal examples), I will discuss how the HR department represents the employees and the firm itself, I will also discuss how the HR role has changed over the years and how it will change even more in the future. First I will discuss the most important roles of the HR department. Personnel development and growth should be the primary focus for the HR department. This will allow the employees to always understand there are chances for advancement and new opportunities. Developing your personnel involves delegating and empowering them to perform tasks on their own. “Empowerment means that the management team of a business shares some of its authority and responsibilities with team members.” (Keefe, 2010) Another way to ensure your personnel are progressing is to provide training opportunities for them within the company. This also gives them “job and career enhancing skills” (Heathfield 2010) which will allow them to grow and gain motivation. Another way to grow your employees is by ensuring there is a good mix of employees within the company. Diversification allows individuals to come...

...tool that proves useful to many of us humans. But the vastness of the internet proves that there are some sectors of the internet that may give ‘negative effects to those who would use lt. But of course, as we all know the internet is also used for many productive and helpful uses. Dokoupil (2012) stated that majority of the human race use the internet and the devices used to access it But with the rising population of users it would be fairly obvious that we are slowly evolving into and age of smart people but even smarter machines. It could be a relatively symptoms of psychosis. Wherein we are consumed by the constantly evolving machines. As people observed in the internet, many stay indoors for longer periods loitering about surfing the net. Message boards and social networking sites often have users that stay logged- in for more than ten hours. Based on a recent internet survey, we see that the majority of people speend most of their time in front of computer screen Now relating it to psychosis. Psychosis is a mental disorder wherein we lose touch reality varying in two forms, delusions and hallucinations. Delusions are false beliefs about what is taking place of who one is. Because of prolonged isolation some frequent intern users tend to develop symptoms of psychosis, hearing voices, seeing things, depression… etcetera. That’s why most experts fear that even though we are developed technologically, evolving machines drive us mad mentally. Actually...

...There are very few conflicts in the human soul that spark controversy when discussing the topics of faith and science. For centuries, people have been rooted in their faith and religion fixed upon their ideological belief system. Consistent across the majority of religions was that this world and all things existing in this world were created by a higher being; a supreme entity. Faith is required to believe in this higher power since no one can physically see it, hear it, smell it or touch it. The theory of evolution claims that this world was created by natural occurrences and that all life forms, including humans, evolved from earlier species. Humans and all living organisms are continually evolving, mutating and transforming. There is no stagnation of life within evolution. The challenges people faced in the 19th century and still face today is discerning the validity of both evolution and personal religion. If faith is required to believe in either, why do people continue to discredit each with such ferocity? Charles Darwin is arguably the most prolific figure in history to convey the theory of evolution. Darwin initially studied medicine at Edinburgh University but later transferred to Cambridge (both located in the United Kingdom) where he was encouraged to study his passion for nature and natural science. In 1859, Darwin published an extremely controversial book titled, On the Origins of Species by Means of Natural Selection. He presented the scientific theory...

...today. We have grasped the concept of it, but implementing all but the most simple of changes is still beyond us. I see many options in this field. From modifying our cells to resist diseases and cancer, to merging our DNA with the DNA of animals. The way I see things unfolding, keeping in mind how society is like today, only the people who make a decent amount of money can afford to get their DNA modified the way they want. Diseases will never go away due to new unforeseen possibilities. Athletes will have modified their DNA to add the strength ratio of a chimp or gorilla to be better at sports. With the rate at how long it takes the majority of the people to accept a new way of life (look at gay rights for example), buy the time the masses can change their DNA, they would have many rules and regulations up and running to make sure people can’t abuse the new found power. In fact by that time there will be failsafe’s added so a criminal can’t go on a warpath and kill thousands of innocent people. Businesses will use it to their advantage as well. If you need a security guard for the night shift, why not give him night vision on top of anything else that would be needed. We could finally explore the planet in its entirety due to being able to adapt to any place on it. Even with all the possible good, the down side to this is possible mutations. We could be no longer considered human. We could even go as far as losing society in general and actually revert to a more basic way...
