This week, we discussed other pieces of evidence that support the theory of evolution. We talked about the fossil record, geologic time scale, plate tectonics, vestigial structures, and comparing organism similarities by bone structure and order, embryotic structures, and DNA. In our lab, students practiced using relative fossil dating techniques to find the estimated age of different fossils. They had to arrange "rock samples" in order, based on their fossil components. We reviewed for our evolution test on Thursday and Friday. Remember that the test and notebook check are on Monday! Next week, we will begin our chapter on classification.
