  • Stars Compare And Contrast

    Laying on the fresh cut grass of your lawn, you watch the sun sink behind the mountains as day subtly fades into night. There is always a minute of darkness as the city holds its breath. No street lights. No cars. Just you and the sky and… the faint glow of a star. Seeing the first star that night, you make a wish and remember the first time you saw one. You still wonder what that speck of light is—How it got to be up there, why it sometimes is so bright and other times so faint, and how it plays an important role in the universe. The street light flickers on above your head, snapping you out of your reverie and reminding you that you still have an essay to write. You sigh, sit up, and walk to your house, the stars quickly forgotten. They wink from the sky and bid you goodnight, but you don’t notice. Just like you, people tilt their heads back to peer at the stars and think about how unlike us they are. Contrary to this belief, stars are more similar to the human race than a person might think. Each star is born, goes through its life cycle, and eventually dies, just like each and every person. If someone were to look at the sky at night and try to decipher the difference of stars with the naked eye, it would be impossible. All stars, from the vantage point of the Earth, seem to be small specks of light. Despite the eye’s inability to recognize the different stages and types of stars, there are more advanced ways to see into space: telescopes. Two of the major telescopes that…

  • Annie Jump Cannon Research Paper

    developed her own classification signifying the comparison with Fleming's and Pickering work as difficulties arose when Pickering could not understand Maury's claim on theoretical concerns that inspired her scheme. This lead to Annie Jump Cannon to continue in 1911 to expand on her research she started in 1901 beginning with an examination of bright southern hemisphere stars using a magnifying loupe. She could distinguish stars down to 9th magnitude, about 16 times fainter than the human eye can…

  • Difference Between Creation And Evolution

    Creation vs. Evolution Creation and evolution have always been argued head to head. Creationism and evolution, both cannot be proved scientifically yet. Creationism is common among people with a belief in God or another god/deity. They believe in the straightforward interpretation of the bible. Evolutionists though believe in what is the big bang theory which simply states that all things came from nothing. There are many other groups of people in these two major groups but they all have the…

  • Dr. Ham's Creation Debate

    Dr. Nye made it abundantly clear that he was a man of faith in evidence, and from fossil records to fulfilled prediction made by science it appeared he held the upper hand on Dr. Ham in regard to the age of the earth. However, because that was not the topic of the debate he will not receive a reward for his stellar presentation. Dr. Nye believe that the two theories (creation/evolution) were mutually exclusive, one talked about the origin of life from the top on down(creation); while the other…

Passage 1: “Our genetic makeup has been adapting in response to where we live and what the weather’s like. The food we eat has evolved to cope with the organisms that eat it, and we’ve evolved to cope with that. We’ve looked at the way we’ve evolved to resist or manage the threat posed by specific infectious…

  • James Bronowski's Intelligent Design

    creative? We will find out if this bond between James Bronowski his notion of the nature of scientific reasoning and Luke Bawazer comparing to Edward Wilsons theory of intelligent evolution. Jacob Bronowski (2012) writes about Copernicus’s route to enlightenment as an obscure theorist challenging the common science of his time, his first stage was his mind to raise him from the planet, and put him enthusiastically, theoretically into the sun. This action signifies the start of…

  • Four Mechanisms Of Evolution

    Evolution is a change in populations over time. It is the population that evolves, rather than an individual. There are four mechanisms of evolution: mutation, gene flow, genetic drift, and natural selection. There were multiple contributors to the ideas of evolution, including Charles Darwin and Alfred Wallace. To begin with, mutations cause genetic variation. Genetic variations are the differences in DNA sequences. The differences in DNA sequences caused by mutations are known as…

  • The Hardy-Weinberg Principle Essay On Gene

    a method for geneticists to study genetic variation and evolution. It is a model that predicts the outcome and offspring of a non-evolving population. This model is then compared to an existing population and the differences between the non-evolving population and the existing population display evolution.12 An example is polyploidy. In animals, polyploidy is extremely rare, however, in plants, polyploidy is common and it is the source of…

  • Examples Of Creation Stories

    ability to live. With the beginning of procreation only a few humans were placed upon the earth. We can infer that throughout procreation there had to be some form of incest. Adam and Eve were the only two people placed upon the earth in the Christian story. Adam and Eve’s children wouldn’t be able to have children without it being incest. This makes the Christian religion more plausible. In the Apache religion, there are 28 people to populate the earth. Thus making a more believable story. It…

  • The Contributions And Complications Of Polycythemia And Human Evolution

    Mutations and errors in sexual reproduction allow for variation within a population. These variations can eventually lead to the complex process of evolution in a species. The genetically derived mutation Polycythemia and the environmentally derived mutation lip augmentations, affect human evolution in a beneficial and detrimental way. Evolution is change in the aspects of a certain species over a period of time. This is caused by mutations which are variations or differences in the genome. Both…
