Vertebrates have two independent extentions of flight evolution. These two evolutionary markers are the aves, and chiroptera. The origin of flight led to two main theories that flight originated form the ground up or from the trees down. One theory does not explain both evolution in flight as it may be possible that the trees down theory supports Chiroptera or bat evolution. The other theory of ground up evolution could be the explanation for Aves or birds. Aves flight origin is believed to have began with the ancestor Archaeopteryx in the late Jurassic era. Chiroptera origin traces back to early Eocene period but a small fossil record is not helpful to establish their origin. Studies show that Skeletal and muscle structure differences could
“Flight Patterns,” by Sherman Alexie, tells an interesting story of a man named William, who is a Spokane Indian and lives in Washington State with his wife Marie and five-year-old daughter Grace. William struggles with living between the traditionalist American and Indian worlds by appearing confident and assured, but on the inside, he is actually weak, fearful, and has an abundance of obsessions. He loves his job and hates it at the same time, He needs to fly for his job, but flying scares him since the terrorist attacks that happened on September 11th. He seems very indecisive and unassured at times. He stays in the same hotel chain, eats at the same restaurants, and has the same exercise routine while
Paul, Gregory S. (2002). "Looking for the True Bird Ancestor". Dinosaurs of the Air: The Evolution and Loss of Flight in Dinosaurs and Birds. Baltimore: Johns Hopkins University Press. pp. 171–224. ISBN 0-8018-6763-0.
The book Flight written by Sherman Alexie is about a 15 year old part Native American
Sherman Alexie’s short story “Flight Patterns” is an intriguing story about many themes, including identity, stereotypes, and the illusions of society. The story is written from an American Indian’s viewpoint and provides and interesting and different perspective on identities and relations in America after the terrorist attack on Spetember 11, 2001. The main character William, a native American man who has a wife and a daughter named Marie and Grace respectively, leaves his family for a business trip. On his way to the airport, he encounters a black taxi driver, named Fekadu, who tells him his story. He is not sure whether or not he should believe it but by the end of their trip together William realizes how much he loves and cares for his
Sherman Alexie’s Flight Patterns tries to tackle a challenging subject. It probes the underbelly of modern life, sifting through the cloudy American mind that’s full of seemingly useless information, in search of what’s truly important in life. This happens through the stories two main scenes. The first depicts William’s relationship with his daughter and wife, and conflicts in life. The second engages William in a taxi-cab conversation that shuffles his priorities and forces him to confront his problem. This pushes him to his tipping point, and when the ride is over, he becomes uneasy and cares only to hear his family’s voice, not about his job, or the fears that had previously been driving forces. Alexie is trying to show that temporary concerns should never come before a thing like family, something that will remain permanent.
The story "Flight Patterns", based in the United States, was about the dilemmas with racial profiling. William, a Native American descent, struggles with his self-identity. William believes everyone around him judges him through his appearance and presentation. I perceive William as having a low self-esteem which portrays him as a negative individual. William always worries about what others think of him. William states, "We're all trapped by other people's ideas, aren't we?"(Alexie 63)
In the book The Invention Of Wings there were many themes written all over it. Though I found that the theme in this book is, everyone should be treated the same no matter the color of your skin. For example, in the book all of Mr. and Mrs. Grimke slaves were treated horrible. Unlike Sarah, at a very young age wasn’t blind on how badly the slaves were being treated. Sarah didn’t believe in any human being treated the way they were being treated. Action speaks louder then words and Sarah definitely proved that when she was given Handful, as her own personal handmaiden slave. Sahara treated Handful as if she was colorless almost like if color didn’t exist in her eyes. Even though Sarah had to be very cautious because she was still living under
The story “Flight Patterns,” which was written by Sherman Alexie was about the severe problems people in this world have with profiling. It doesn’t matter if you’re White, Black, Indian, Spanish, rich, or even poor everyone does it. The one character I would like to focus on in this story is called William.
The species A. afarensis is one of the better known australopithecines, with regards to the number of samples attributed to the species. From speculations about their close relatives, the gorilla and chimpanzee, A. afarensis’ probable social structure can be presumed. The species was named by Johanson and Taieb in 1973. This discovery of a skeleton lead to a heated debate over the validity of the species. The species eventually was accepted by most researchers as a new species of australopithecine and a likely candidate for a human ancestor.
The main purpose of this lab was simply to study two factors of Natural Selection: Genetic Drift and Fertility. The first of these factors in the study was Genetic Drift. In this section of the lab, there was one main question to answer: What effect does population size has on random mechanisms? For this question, I hypothesized that if the population is smaller, then the random mechanisms will have a greater effect on the populations. I believed that this was because basic math principles would allude to the idea that any bad random mechanism to a small population would harm a greater percent than a larger population. With a greater portion of their population gone, then the amount of turtles reproducing would lessen significantly.
Fossil evidence suggests that the Cathartid (New World) vultures have been around for quite some time with two fossil species dated from the early Oligocene (about 35 million years ago). During the Pliocene and Pleistocene (about 2 million years ago) th...
What is evolution and how does it work? Evolution is the theory of how one form of life changes into another form. Evolution also is the change of a population’s inherited traits from generation to generation. Evolution helps to explain why an animal, human, and plant looks the way it does and acts the way it does; it gives an explanation of the history of life. Genes come in many varieties and the evolution helps to make it happen. Mutation, natural selection, genetic drift, and gene flow: the four forces that make the evolution work.
The northern sparrows have adapted to a larger body than the southern sparrows, in order to survive lower temperatures. Along with these similarities, evolution and creation both acknowledge that apes and humans show resemblance. Evolution and creation both recognize the comparable characteristics that humans and apes acquire.
In Katherine Mansfield 's "The Fly," an older gentleman referred to as "the boss" struggles with a fight. However, it was a fight with his own thoughts and despair. Although the boss is able to forget in the end, who is to say that this has not happened before or won 't happen to him again. The sadness he feels for his son will always be there, but he just cannot bring it to the surface. Although the fly drowns as if to symbolize his despair, his need to cope is gone. The boss as depicted by Katherine Mansfield in "The Fly" seems to be inadequate physical health but is fighting his own depression that he thinks he should be feeling for his son, yet the fly provides a distraction that he needed to move on.
... originated from one ancestor, the chimpanzee. Not only did we evolve physically, but we also evolved culturally. The early behaviors of chimpanzees evolved to the behaviors shown by humans today. Human evolution has shaped our current society. It is still currently changing our society and humans are still continuing to evolve more and more. Scientists are still researching more and finding more important fossils which show us that much more of our ancestors, who are chimpanzees.
