Dolphin Evolution free essay sample

A Dolphin Organism Evolves Anthony Youmans BIO/101 Pamela Buckman April 13, 2013 Kingdom: Anamalia, Phylum: Cordata, Class: Mammalia, Order: Cetacea, Sub-order: Odontoceti, Family: Delphinidae, Genus: Delphinus, Species: Delphi’s, or better known as, Dolphin. Dolphins occupy all oceans and major seas, even some are in larger river systems. This paper will cover characteristics of a dolphin, the ancestry to the modern dolphin, and what adaptations the dolphin has gone through to be the survivor it is today. Characteristics Dolphins are very social creatures and use interaction for the purpose of hunting, defense, and reproduction. Normally a dolphin will stay in a long-lasting group of 2-40animals called pods, but larger groups of hundreds of dolphins have been reported and those are called herds. Dolphins are carnivores that feed on fish, squid, octopus, cuttlefish, crabs, shrimps, and lobsters. Dolphins are food for sharks, killer whales, humans. Man is the most dangerous predator for the dolphin.

Additionally, studies are currently being done to evaluate the effect of pollution in the water on dolphins. Dolphins bear live young, and the mother nurses the calf with her milk and provides care. The calf is nursed one and one half to three years and a mother will stay with her young three to eight years. Dolphins are believed to live about 30 years. Dolphins vary based on their ecosystem and what is required for them to survive in their niche. In the Gulf of Alaska there are few dolphin species, one of which is the pacific white-sided dolphin. This dolphin has a short, rounded beak with about 30 curved teeth in each side of the jaw. Very energetic and is seen frequently leaping, belly flopping and summersaulting. It is attractively marked with black back, gray sides and white stripes from its eyes to its tail. Its dorsal fin is tall and sharply hooked, its flippers are small and rounded at the tips, and its flukes have a notch in the center. They are seven to eight feet in length and weigh up to 300 pounds. Beginnings (EO. Reddit. com, 2011) Dolphins, porpoises, and whales are related in some way. Fossil has been found that indicates early dolphins were aquatic 40 – 50 million years ago. It is believed that animals that spent a great deal of time looking for food around water areas went through a stage before becoming committed to the water. Once in the water records show that by changes in their teeth it took millions of years for true cetaceans to develop. Adaptations (Animalfiles. com, 2011) The dolphin has come a long way from the once amphibious animal it is believed to have evolved from. Fossil evidence shows that once dolphins long ago decided to be aquatic, it it wasn’t long for bones of the hind limbs to disappear. Anatomically, dolphins’ bodies have become more streamlined to move in the water. Their front limbs evolved into flippers and their powerful tail is their main propulsion mechanism. They have a thickened body with a raised head that caused the vertebrae neck to fuse together. Instead of a major blood supply to the brain on the outside of the neck, the dolphins blood flows through an artery in the vertebrae that provides a constant supply of blood, which is most essential when diving into the depths of the ocean. The dolphins’ skin is extremely smooth, hairless, is thick, and lacks glands. This skin is kept smooth by constantly sloughing off and being replaced. On average their skin is replaced at a rate nine times faster than a human, and in the case of the bottlenose dolphin, the outer most layer of skin is replaced every two hours. Dolphins tent to rely on their sense of hearing to survive. They are said to have good eyesight, but in the blackness of the ocean, other senses have had to develop for survival. The shape of the dolphins melon (the fatty tissue in front of the blowhole) acts as a lens to focus sound when the dolphin produces high pitched clicks for echolocation. The dolphin has adapted well to its watery world, and evolved in shape and skill to breed successfully and thrive. The fascinating skill of echolocation gives the dolphin a huge advantage when feeding in the darkness of the ocean. Dolphins are very energetic, kind, and smart animals. For the most part they are left alone in their ecosystems and traditionally only humans to fear. References American Cetacean Society (2011). Pacific White-Sided Dolphin.

Parklife by Blur free essay sample

OK, OK, before I start this review, let me just say this: I’ve never liked so-called â€Å"boy bands†. Absolutely can’t stand them. When they don’t have screaming teenage girls at their feet, they’re writing cutesy songs about peace, love, and happiness. Even the masters of the genre, The Beatles (if one must put them under that genre) were huffing LSD while scribbling down â€Å"All You Need Is Love†. Yet for some reason or other, I decided on a whim to take a moment to listen to the 90’s Britpop group Blur’s third album Parklife (probably because of it’s rave review in my â€Å"1000 Albums You Must Hear Before You Die† book). And boy, was I glad I did. In short, the album is definitely NOT your typical â€Å"boy band† CD. In fact, it’s most likely like nothing you’ve ever heard before or since.Rock, electronica, psychedelia, pop, punk, and even a little bit of thrash (the obnoxious Bank Holid ay) all make their statement within the 52-minute course of this earth-shattering album. We will write a custom essay sample on Parklife by Blur or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Not that Parklife entirely abandons it’s Britpop premise, of course. The surprisingly Clash-esque â€Å"Girls and Boys† will most definitely give teenage girls something to swoon over, as is the slightly cheesy, singalong title track. Also, Damon Albarn’s vocals could sound a lot like the Beatles at times (especially on â€Å"To The End†). But with this, their magnificent third album, Blur managed to whip up something that would appeal to both screaming teenage girls and hard-rock fans like me alike. And that, my friends, is no easy feat. Small wonder then, that it received the highest rating (5 out of 5 stars) on the highly critical music aggregator website AllMusic.

Voltaire Essay Example For Students

Voltaire Essay Voltaire was a talented, assertive, and controversial French writer from the eighteenth century enlightenment period. He was born in 1694 to a wealthy family in Paris, and given the name Francois-Marie Arouet. During the early years of his life Voltaire endured many hardships. For instance, his mother passed away when he was seven leaving only his father and older brother to raise him. Unfortunately, this added insult to injury as Voltaire despised both his father and brother. Nevertheless, Voltaires determination allowed him to rise above his early misfortunes, and he later went on to pursue college at the College of Louis-le-Grand in Paris. Once there he studied literature, despite his fathers wishes that he pursue a carreer in law. It was during this stretch of the young writers life he first voiced his oppositions on the established church and government in France. By the young age of twenty two Voltaire was exhiled to Sully-sur-Loire for writing a satire of the Duke of Orleans, the ruling regent of France. Voltaires bouts with those in power continued throughout most his life. In fact, he was subject to brief spells in prison on more than one occasion for aggrevating the reigning Monarch. We will write a custom essay on Voltaire specifically for you for only $16.38 $13.9/page Order now Despite French governmental attempts to deter or imprison him, Voltaire went on to become an exeptional philosopher, author, and leading figure of the enlightenmentThe overall message of Candide is that every human being has the power to carve out their own destiny, and is not subject to Gods grand plan, or predestination. In addition, Voltaire used the book to drive home his belief God did not divinely pick the world from the cosmos and therefore the best of all possible worlds. To get his propositions across Voltaire constructed the character Dr. Pangloss, the tutor of young Candide. The name Pangloss translated meant windbag, and implied a person was all talk. Early on in the piece Pangloss made it evident he thought the world he lived was Gods first choice when he stated, since everything was made for a purpose, it follows that everything is made for the best purpose (20). Of course his philosophy was passed on to Candide who took it with him, as he set out on his own. However, as the story progresses Candide encounters much chaos, and brutality that forced him to question his beliefs. One example in the story found Candide captured by the Bulgarians and forced to run the gauntlet until he begged them to smash his head in. Moreover he later discovered another terrible act when he witnessed the execution of an admiral for the mans failure to succeed in battle. Upon his inquiry of the justice of the act Candide was told, it is a good thing to kill an admiral from time to time to encourage the others. The author uses the scenarios above intentionally to question how such things could come to pass in a world blessed with Gods intervention. The motives Voltaire had for writing Candide were his disagreements with the establishments of Absolute Monarchy and the State Catholic Church. He not only argued against their existence as powers, but also with the rules, belief systems, and laws they imposed on the general populous. Voltaire believed men should have the right to worship what they chose, and the only acceptable spiritual belief was Deism. Candide specifically attacked the largely accepted philosophy of Optimism, theorized by Gottfried William von Leibnez. According to Voltaire, the philosophy was perpetuated by the Catholic Church to keep the people from questioning the many hardships they endured. In addition to the attacks he waged personally, Voltaire was one of the leading figures of a group of social critics called the philosophes. The group spent their time criticizing Louis the fourteenth and fifteenth, succession of the crown by heredity, and the other aspects already covered. In short, the political climate building up to the first French Revolution, and the beliefs Voltaire and his comrades the philosophes held concerning the widespread social injustices, contributed to Candides creation. .uba99363df0d4d3c7465fa085887cd333 , .uba99363df0d4d3c7465fa085887cd333 .postImageUrl , .uba99363df0d4d3c7465fa085887cd333 .centered-text-area { min-height: 80px; position: relative; } .uba99363df0d4d3c7465fa085887cd333 , .uba99363df0d4d3c7465fa085887cd333:hover , .uba99363df0d4d3c7465fa085887cd333:visited , .uba99363df0d4d3c7465fa085887cd333:active { border:0!important; } .uba99363df0d4d3c7465fa085887cd333 .clearfix:after { content: ""; display: table; clear: both; } .uba99363df0d4d3c7465fa085887cd333 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uba99363df0d4d3c7465fa085887cd333:active , .uba99363df0d4d3c7465fa085887cd333:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uba99363df0d4d3c7465fa085887cd333 .centered-text-area { width: 100%; position: relative ; } .uba99363df0d4d3c7465fa085887cd333 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uba99363df0d4d3c7465fa085887cd333 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uba99363df0d4d3c7465fa085887cd333 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uba99363df0d4d3c7465fa085887cd333:hover .ctaButton { background-color: #34495E!important; } .uba99363df0d4d3c7465fa085887cd333 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uba99363df0d4d3c7465fa085887cd333 .uba99363df0d4d3c7465fa085887cd333-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uba99363df0d4d3c7465fa085887cd333:after { content: ""; display: block; clear: both; } READ: Confucius (3863 words) EssayCandide made it clear that during the time it was written people were suffering for a plethora of reasons.

Harley Davidson Cultural impact of media on women Research Paper

Harley Davidson Cultural impact of media on women - Research Paper Example People are easily updated with the happenings around them through those media as writers, bloggers, newscasters and columnists relay the information to the viewers. Sometimes those relayed information may not be the whole truth at all as sometimes works of fiction do affect the rituals and culture of people. Massive influence may be achieved through mass media and sometimes those become the avenue for negativities in the society to flourish. The widespread of the influence of the negative practices in the society may be attributed to the media that may be intentional or unintentional. It is considered as intentional when people truly want to influence others with their deeds and beliefs that may pose risks and hazards to the society and considered as crimes. Other activities that may be seen in media but are not considered crimes but may challenge the border that separates the morally acceptable beliefs and immoral ones. The cases that may arise from mass media that are in the bounda ry of right and wrong are the issues of gender and sexuality, abortion, euthanasia, divorce, no religious affiliation, and roles in the society. In particular, the paper will talk about the effects of media to the lives of women especially in the cultural aspect. Harley Davidson would be the subject for the media effects on women as that company endorses motorcycles and how it blends into the culture of women. Then several questions may have arisen from the motorcycle craze and its influence on the female gender. Does it make women more masculine? Does it encourage violence and other negativities in the society? What are its other impacts? Does motorcycle craze give any positive influence to the society as a whole? Will gender roles be greatly affected? The three previous studies about the effects on women would include â€Å"Girl Power† and Participation in Macho Recreation: The Case of Female Harley Riders by Catherine Roster, Subcultures of Consumption: An Ethnography of t he New Bikers by John Schouten and James McAlexander, and Examining Gender Images, Expectations, and Competence as Perceived Impediments to Personal, Academic and Career Development by Lorraine Wilgosh. The study of Roster talks about the women empowerment gained from the inclusion of some women in motorcycling sports which is played mainly by men. On the other hand, the study of Schouten and McAlexander goes into the culture of consumerism and an analysis was done on how it brings about the change in the society and behaviors of people especially for bikers. The last study was about the discrimination, stereotyping and societal imaging of what women should be and those effects upon the development of young girls. Other sources that will be used for the study are Older Women, Liberation and Lifestyles: Self-Care and Other Care, Depicting outlaw motorcycle club women using anchored and unanchored research methodologies, and Brand Morphing: Implications for Advertising Theory and Prac tice. Method The study was done by looking at the previous studies from background, methods to results, analysis and conclusion. It did not utilize primary sources and did not have any actual experimentation and first-hand data gathering as it relied purely on the theories and results laid down by the previous studies and reports. It made use of the six journal articles mentioned in the background section of the paper. Each source had its own contribution

How has information technology changed the daily lives of enlisted men Research Paper

How has information technology changed the daily lives of enlisted men and women serving in conflict zones overseas - Research Paper Example With the aid of academic literatures, this paper also aims to define information technology as used in this paper to provide a background as to how information technology relates to the US military, and provide a historical background of the utilization of IT in the US military forces to probe on how technology has affected military forces across different eras. 2.0 Information Technology (IT) Generally, Information Technology or IT is the processing of information by the computer systems which are greatly used for communication, data security and storage (Stoyles, Pentland, & Demant, 2003, p. 4). Thus, information technology helps the people in gathering, sharing and storing of data in a convenient and fast manner. Moreover, according to Yadav (2006, p. 2), information technology includes television sets, published works, computers and the Internet (which are common technologies used at home and offices) and any other media platforms where people can acquire information. In the cont ext of the military forces, information technology relates to the Revolution in Military Affairs (RMA) wherein information technology is used for weaponry, surveillance mechanisms, processing of information, and organizational transformations of different military units (Goldman, 2005, p. 1). These benefits center on the organizational advantage of the force. Part of the utilization of information technology of the US corps is also to provide personal benefits to the military soldiers as privatization of housing through IT, skills development and telemedicine programs. 3.0 IT and the Military: History In the early days of war fighting, various nations have adopted new technologies that brought radical changes in fighting. The end of World War II has marked the birth of atomic bombs where it was later developed to hydrogen bombs (Perry, 2004, p. 235). As people become more knowledgeable on the use of technology, the weapons and war instruments have also metamorphosed to a more advanc ed state. Furthermore, as the Soviet Union and the United States of America are creating war technologies based on fatal situations, both countries have developed missiles (Perry, 2004, p. 235). War weaponry continuously evolved which now includes new systems as satellites, smart sensors and new aircrafts to name a few. However, during the 1990s, as information technology slowly shapes the American society, and likewise, the US military has also acknowledged the importance of such technological advancement to further develop its strategies and principles that will ensure the dominance of the forces of the US military (Dombrowski & Gholz, 2006, p. 1). As information technology in the military forces centers on the war fighting improvement, they have implemented â€Å"network-centric warfare,† thereby providing a centralized infrastructure that allows communication, detection mechanics, commanding and controlling systems, combat information and battleground bearings among other s that can be accessed by various military personnel (X. Wang, Wei, & H. Wang, 2012, p. 573). From the mechanical war instruments, the advent of more advance technologies paved way for the
