Evolution Questions

  When talking in class about evolution I thought of questions that evolution itself can't answer yet and may never be able to.  Why is the importance of our DNA similarities such great evidence when we have some of the same genetic make up of a banana?  Why do people not take into account natural disasters changing the layers of the earth when they consider the fossil record? How do we explain why we are the only bipedal creatures on the earth today if we are so much like so many other creatures? Some of these questions I don't think evolution can answer and that is where the questioning of evolution can easily take control.  The changes that we can see in microevolution are some of the only evidence we can see taking place today that can't be argued.  After learning about evolution I feel like I know more about it and the questions I have are more advanced research questions that I would never have had before.

Evolution's most convincing evidence

  When researching evidence for evolution I think that the most convicing evidence would to the similarities in the DNA and the similarities in development.  When looking at the development of different animals it is easy to notice that the embryos look the same for a long period of time.  The process in development can show that they all could have been the very similar at one time and then they changed over time to adapt to changes in environment, climate, and food available.  The DNA is also convincing because it  shows how we could have had come from the same common ancestr as monkeys and chimps.  The DNA is also unreliable because we may some of the same as DNA as a monkey but we have the same as a banana as well and in evolution where is nothing saying that humans came from bananas in any way. 
   I think I have learned a lot more about evolutiona and I understand it a lot better even if it will never agree with my religion. I think that it is important to learn about evolution because it is a theory that keeps on changing and we need to be current in our studies of sciences.  Evolution will keep changing as long as new information is being found and tested out.

Evidence of Evolution

  When looking at the different evidence that scientists use when they try and prove evoultion it is easy to see they people believe in evolution.  The fossil record is the only part of the evidence that can easily be argued by those who aren't scientists because we can prove that there is no fossil of the missing links anywhere to be found and that the earth isn't always in consecutive order when it comes to the crust layers where the fossils are found.  I think that the best evidence would be natural selection because it can be seen today aqnd seeing makes things a lot easier to believe.  This was a interesting topic because I could see how we could be easily related through DNA and structure.

Natural Selection

  Natural selection is the main element when talking about evolution.  Evolution wouldn't be a believeable theory without it because there would be no change needed for the animals.  Natural selection is still something that we can see today in microevolution.  Animals that are stronger live longer and have more control of habits and the weaker ones die off and are at the bottom of the food chain.
  I think that natural selection helped me change my view in evolution in the fact that I can see where evolution comes into the picture of life.  Without natural selection there would be no population control within a species.  I think that talking through evolution has helped me understand why people believe in it.  I think that talking about evolution without religion as the base makes it easier to understand and less biased.

Evolution over time

  When reading the different documents from the past about evolution it makes the connections seem clearer.  All of the scientists had something to do with evoultion how it is today is some way or another.  One of the ways that they helped evoultion along seemed to be publishing their ideas so others could see this is how Darwin was able to help formulate his ideas and conduct his research.  I can understand why Darwin would wait so long to publish his findings because I can see where many people would have seen what he was presenting as a religious attack.  His research was more complete after all the time he spent on it.
   Learning about evolution and how the ideas have grown and changed helps me understand it better.  I will probably never believe in evolution but I now have a better scientific understanding of what it really means.

Evolution after the timeline

   In looking at the timeline of the world from the evolution standpoint I learned the importance of new species showing up after a massive extinction.  There are large periods of time that we have no data of any new species or any extinctions so it makes me wonder what was going on in this time is there links missing or what was really happening.  There is so many new developments of new species and diversity of already exhisting species in the last 1 million years. 
    I still feel like there is too many gaps in evolution for it to prove accurate in the way that we evolved from the common ancestor of the monkeys.  I think that we need to find true intermediate fossils to make macro evolution a possibility.  I never really thought about evolution in the micro level before and talking about the differences has helped me understand it better.  The timeline helped me understand what ideas and events evolutionists have based their beliefs on.

Evolution

Evolution is the belief that the world and its in inhabitans have changed over time and frmed new organisms.  That everything came from a secific set of organisms and the changed with the Earth.  I don't feel like evolution is true because it goes against everything I have learned in my religion.  I would like to learn more about the ideas and studies that are about evolution if they help support or disprove it. I would like to learn more about evolution without the religious mindset behind the teaching.
