Why are there warm plant fossils from a tropical climate being found in Antarctica? Continental Drift can help explain why. Continental Drift states that the continents and the plates their on drift on top of the mantle, a layer of molten rock under the Earth's surface. Pangaea was a super-continent of all the continent today put together. It split apart to form our current continents that will, in millions of years, have moved again. This also helps the theory of the plants being found in Antarctica.


To state this theory, Antarctica had must have been warm at some point, right? Scientists believe that Antarctica was actually in a warmer climate until Pangaea broke apart. Since the continents moved, climates changed as well. Antarctica floated to a colder area and, with the icy cold water surrounding it, slowly grew to be an icy place.
 
Say you had an old bone and wanted to date it. What would you do? How would you do it? You would probably want to use the Carbon-14 method of dating things.


You would analyze the Carbon-14 material in the rock and take a percentage of it compared to the Nitrogen-14 material. The more parent material there is, the younger it is. The more daughter material there is, the older it is.
 
     Natural Selection is a theory developed by Charles Darwin and Alfred Wallace. Darwin, however, usually receives the most credit. Darwin developed the idea by taking notes on finches he saw on his voyage on the HMS Beagle. He noted that finches on the Galapagos Islands were similar, but different and that their beaks helped them survive with how they acted.
     Charles Darwin also wrote On the Origin of Species, a book stating his theory with evidence of it. He suggested that species evolved over time with small genetic variations that helped them to survive. Over millions of years, today's species evolve into what we know today.
