Evolution review Highlights of what you need to remember: LEQ: What experiments led to the development of the scientific explanation for the origin of life? LEQ: How can we use endosymbiosis to support the theory of the origin of eukaryotic cells. • Experiments from Pasteur and Redi • Experiments from Miller & Urey, Margulis, Oparin and Fox • Terms – Biogenesis, Abiogenesis, primordial, endosymbiosis and endosymbiotic theory Review foldable LEQ: What are the major causes and effects of natural selection? • Darwin’s development of the theory of natural selection • Conditions for natural selection to occur • Examples of natural selection: Galapagos finches, bacteria resistance to antibiotics, insect resistance to pesticide, etc. • Speciation • Review foldable LEQ: How do mutation and genetic recombination impact genetic variation? LEQ: What influence do genetic drift and gene flow have on evolutionary change? • Review DNA mutation and protein synthesis. • Describe how mutation and genetic recombination increase genetic variation. • Review foldable for causes of evolution • Mutation, Natural selection, genetic drift, founder effect, bottleneck effect, migration, gene flow. • Review foldable LEQ: How can we analyze the various supporting evidences for the scientific theory of evolution? • • • • • • • • • Fossil record – also radiometric dating Comparative anatomy Comparative embryology biogeography molecular biology observed evolutionary change Molecular clocks (review graphic organizer) Terms – analogous structures, homologous structures, vestigial structure, embryology, molecular clock Comparative embryology Vestigial structures are structures that no longer have a use. Ie. Molars in vampire bats (consume a liquid diet) LEQ: How does brain size, jaw size, language, and use of tools show evidence for trends in hominid evolution? • Observe skulls, jaws and skeletal variations • Compare/contrast modern humans with their hominid ancestors. • Terms- prehensile tail, bipedal, hominid LEQ: What evidences led to the modern classification system over time? LEQ: How are evolutionary relationships used in determining the classification of organisms? • Linnaean system and the new changes due to the knowledge of DNA • Identify the domains, and their characteristics, the kingdoms and characteristics. Include type of cell, autotroph/heterotroph, and reproduction type. • Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species • Terms – Binomial nomenclature, phylogeny, taxonomy, domain, genus, species, cladogram, clade, taxon, add node and speciation event. • Review animal kingdom cladogram http://evolution.berkeley.edu/evolibrary/article/evo_05 http://www.ucmp.berkeley.edu/alllife/threedomains.html
