Bio - we finished up the Evolution unit by reviewing some aspects of modern evolutionary theory such as gradualism vs. punctuated equilibrium, and the strengths and weaknesses of each of these hypotheses. We looked at phyogenetic trees, which show evolutionary relationships. These tree diagrams are assembled mainly from biochemical evidence, but geological, cytological, embryological, and anatomical evidence are also used.
Study for Monday's exam! Plenty of practice tests/quizzes on Edline. There is also extra help on Monday morning, a perfect last chance to ask questions just before the exam.
