     You may be able to find temperate climate fossils in Antartica because for many reasons. One reason may be because there was once a time where all the continents were together. That means that one day a long time ago, there must have been a temperate climate. So,as the years passed and the plate tectonics moved further away from each other. So, the climate must have gotten colder and colder as it got separated away more.
      So, I was researching about Antartica, and I found out that Paleontologists have found prove that Antartica might have been next to places that had temperate climates. They think that as the years passed by, the organisms that were of that time must have been left there. Then,sand must have been deposited on top of the dead organisms causing a fossil to form in those  rock layers. If they were trying to find the age of those fossils they could find it easily if it is close to superposition. Superposition is the law that states that if there are undisturbed rock layers then the top layers are the younger ones and the bottom ones are older.
      If this is the case, they would be able to ensure that those fossils were of the time when Antartica was connected with different places. So this is why I think that these fossils were found. I think they were   there because of the time that Antartica had not yet been separated from the big continent there once was!

      To learn our vocabulary we do Quizlet cards. I think they are very helpful because they actually help me learn. I think they help me learn because they are very easy to use and they get my attention. I do study with them before my test the previous day. I use them because it lets me go through the ones that I do not understand. What is really cool about them is that they have many good activities that can help you remember the words. For example, they have games that let you type in the vocabulary and it kind of motivates you to bet the speed every time. 
       I also like how you can test yourself on how many words you know by pretesting yourself. These activities help me learn my vocabulary words so much better than anything else I have tried. So, I would not suggest we do something. It would just confuse and it would not help as much as Quizlet does. This very interesting program, gives us choices to choose different methods to use so that we will be able to study. I think that we should keep using them to help us study.

Charles Darwin

     When Charles Darwin made his theory on evolution  he got a lot of information from other people that had information that he needed. When he made his theory on Evolution he made many concepts that had to do with Evolution. One of those concepts was natural selection. Natural selection is when there is a species and they reproduce sometimes they reproduce more than they will survive. Those who do survive, get some traits from their parents. Some may inherit traits that will help them survive much longer than others. Others though will not be lucky enough and they will get traits that are not as helpful. Soon those will die. Those that do survive then mate with each other to produce fertile offspring. Now their offspring have more chances of survival because they got useful traits from both parents. 
      Evolution is also a theory that Charles Darwin made. Evolution is the process in which things slowly change. All species go to changes through times. Charles made many different observations in his travels that helped him make his theory. The animals in his travels were the ones that made him fully understand what he was thinking. Through his theories he had the collaboration of many people. Those people helped  make his theories more understandable.
        Anyway Charles Darwin got information from different resources. The information he got  from many collaborators contributed to  his theories about evolution and natural selection. First of all, he found ideas about evolution on his travels by comparing the very familiar finches he saw in some of the islands he went through. He considered their beaks and saw how they might have changed in time because of their environments. Thomas Malthus was also very helpful. He helped Darwin understand more about the finches and about populations and how it affects the evolution theory. He played a very important role in natural selection. Charles Lyell was also of great help. He showed and more throughly explained how things change. He made Darwin understand how things also change in geological ways. As you can see the Father of Evolution, did not just come up with the thoery by himself. He got so much information from other people too. That helped him a lot!
