On January 24 our class had a guest speaker for Evolution. The guest was Louise Mead; she had been studying evolution for about 10 years. She introduced Charles Darwin and his role in evolution. Her presentation included cladograms that showed the evidence of evolution. There was also evolution-related vocabulary, such as: Natural Selection, Genetic Drift, Phylogenetic, Biogeography, Comparative Anatomy, Molecular Biology, and Fossil Record. There was also some interesting evidence for evolution. One where salamanders that were closely related were found in different parts of the world. Another where there were visible patterns of evolution in two species of butterflies. There was also the great experiment when mouse genes were inserted into a fruit fly, the amazing thing was that the fruit fly accepted the genes. These are just a few examples of evolution, there are plenty more all around us. Altogether, the presentation was very interesting and educational.
