There have been many theories of why, indeed, the sky is blue. Although, I cannot reveal those theories, I will attempt to pretend, as if, I was an individual who didn't know why the sky is blue. I, myself, actually have two theories of why I believe the sky is blue. For one, I believe the particles, floating in the air, somehow condense, and create the color blue. I have always believed this, and in fact, when the sun goes down, the sky suddenly changes color. In that case, you can barely see the sun on the horizon, there fore the light is probably being reflected. If you were to look at the planet Earth from outer space, it would seem very life like, and earthy. Some of us aren't quiet sure why the sky continues to be blue.
   Another one of my judgemental theories, is simply the fact that, there might be light reflected from the Earth. We are constantly in a rotation on our axis, so when we are finally looking at the sun, we can have some type of light. The light is then reflected from a specific place, and the sky is appeared to be blue. This logic of mine, might not be as sophisticated as others may put it, but my opinion isn' as deft as it seems.
 
Over the years, scientists have become more skilled in the art of discovering fossils, and knowing how long ago they actually were. Some fossils go all the way back into the Paleozoic era. Our time has been broken up into several eras, epochs, and periods. We use the geologic time scale to determine which era or time period comes first. The fossils that have been found in colder climates, such as Antarctica, have been looked up, and examined. Some geologists still have no clue, but the rest have a general idea of where they came from. Several millions and billions of years ago, all the continents were once together, in a form known as Pangea. Pangea contained all the land masses and held real life as well. All was well, until volcanic eruptions, and plates began to slip under the earth, causing the continents to break apart. The mammals, or living organisms on those land masses were know broken apart.
     Those organisms could just have easily stayed on the continents, and died there, have the result of the fossils in the colder climate places. Another popular theory, is that the climates from back then could have been much different from what they are in contemporary times. The sun could have created much more warmth on those parts of the earth, and as time changed, they slowly became cold and dreary. 
 
We are currently beginning a new project, to be exact, the zoo project. The point of the zoo project, is to collect enough information, so you know your animal well enough. Some of these animals may be a bit easier to do this project on, while others remain difficult. The animal that was given to us is known as the Addax. The addax lives in the Sahara desert in Africa, and has spiral like horns. Both genders contain these horns. There is indeed, a distinction between the males and the females. The females tend to be a tad smaller than the males. Both change colors depending on the seasons. The warmer the weather gets, the lighter their coats become. Their coats are specialized, to reflect the hot sunlight, so they can maintain the same body temperature.
      Addax's must adapt well, since they live in an extreme environment.The desert can get up to 120 degrees and maybe even hotter. They have to keep cool at all times, and they use several methods to do so. For one, they are similar to cactuses. They drink lots of water at one time, and have tiny pouches in their stomach lining, so they can maintain that water for a while. They shelter near rock, and cool sandy hollows. As nocturnal as they are, they do most of their traveling at night, simply because the weather is much, much cooler. The addax is almost extinct, and is critically endangered. Survival is important for them.
 
Throughout the history of science, discoveries were among them. Some discoveries pleaded to have a better concept than others, while non important discoveries remained standing alone. In all truths, I believe that the most important discovery had o be DNA. DNA was actually founded by several people, in which most of them received an honor for them. All, but one individual was honored greatly. DNA is one of the most important in my opinion, simply because DNA is the core of all living things. It's not exactly what keeps us healthy and living, but instead, what we are created from. As previously discussed, DNA is what determines your traits. DNA is also what the cells contain within them.
       Four individuals, Watt, Crick, and Rosalind Franklin all distributed to DNA. Each were equally as important, as they all had a part in it. Some people might believe that DNA would have been discovered anyway, with time. The fact that they were able to discover DNA back then, was amazing. They didn'ty have the best type of technology, but their discovery is the best, compared to modern day discoveries. Althoguh DNA is important, an atom was also descovered. This atom wasn't asny atom, but it had the ability to
