BOTMBIOZOO 1005 Concepts of Biology Outline of topics covered for Midterm 111 Nov 25 2008 7 nal version posted 20 Nov 2008 DISCLAIMER This outline is meant to help you organize your lecture notes It is not intended to be a substitute for your lecture notes Furthermore it is NOT EXHAUSTIVE Just because a word or phrase does not appear on this study guide doesn t mean you don t have to know it In general you are best off studying your lecture notes and letting this outline serve as a guide to help you get your notes organized Overriding topic for this portion of the class the history and diversity of life 1 Natural selection and evolution A Evolution biological de nition B Darwin s contribution to scienti c thought about the diversity of life the two main ideas in The Origin of Species C How various lines of evidence are consistent with each other and with evolutionary thought 1 fossil record and how radiometric dating attaches dates to fossils 2 biogeography 3 comparative anatomy including homologous and vestigial structures 4 molecular biology 5 experimental evidence What speci cally do each of these lines of evidence tell us about evolution in general and human evolution in particular Natural selection as an important mechanism of evolution 1 Requirements for natural selection to occur How arti cial selection is similar to and different from natural selection Examples of natural selection What do biologists mean by fitness and unequal reproductive success How natural selection selects for adaptations to the prevailing environment Sexual selection as a variation on the theme of natural selection by resulting in adaptations that enhance reproduction but not always survival Genetic drift as another mechanism of evolutionary change two types of genetic drift bottleneck effect and founder effect Why is genetic drift most important in small populations F Why is evolution inevitable in every population that is what conditions must be met for a population NOT to evolve Speciation development of new species De nition of the biological species concept How reproductive barriers prezygotic and postzygotic keep closely related species from interbreeding What are examples of each type of barrier How geographic barriers plus different selective forces or sudden genetic changes can produce the reproductive barriers that lead to speciation Gradualism vs punctuated equilibrium as two hypotheses for the pace of speciation over long periods of time 11 Origin and History of Life A Timeline of the major events in the evolution of life how do we know Earth s age B Probable stages in the development of the rst life forms what evidence do we have for the events at each stage III Diversity of Life A Prokaryotes domains Bacteria and Archaea 1 Examples of and reason for the enormous metabolic diversity among prokaryotes 2 Similaritiesdifferences between domains Archaea and Bacteria U 99930 P1 Q 4 0 U P1 3 Groups of Archaea not by name but by preferred habitat 4 Importance of bacteria to humans ecosystems and history of life Kingdom Protista Evolution of eukaryotes membrane infolding to yield internal membranes J Pub L to yield 39 39 r39 and 39 39 A la evidence for each theory Characteristics that organisms in kingdom Protista share Examples of metabolic diversity among Protista Characteristics and examples of protozoans slime molds and algae Differences between unicellular colonial and multicellular organisms How might multicellularity have evolved and what evidence supports the hypothesis Elk59 Kingdom Plantae 1 Characteristics of land plants and evidence supporting the hypothesis that plants descended from green algae 2 How selective forces in water are different from selective forces on land 3 How each of the following land plant adaptations contributes to survival andor reproductive success cuticle stomata vascular tissue xylem and phloem lignin roots pollen seeds fruits 4 Four major developments in the evolutionary history of land plants vascular tissue pollen seeds and owersfruits Which plants have each adaptation 5 Four major groups of plants mosses ferns gymnosperms conifers angiosperms What are the characteristics adaptations reproductive features and habitats of each Be sure to use the table I handed out in class to help you see the patterns in characteristics 6 Why animals need plants and why many plants need animals Why are pollination and seed dispersal important to reproductive success Kingdom Fungi 1 Characteristics of fungi 2 How fungi acquire their food the role of hyphae 3 Asexual and sexual phases of fungal reproductive cycles what mushrooms are for 4 Why fungi are important decomposition symbiosis mycorrhizae and lichens 7 what are they cause disease in plants and animals commercial uses Kingdom Animalia 1 Characteristics of animals 2 Embryonic development in animals blastula gastrula 3 Major developments in the evolutionary history of animals true tissues radial vs bilateral symmetry complete digestive tract pseudocoelomcoelom segmentation How is each feature adaptive 4 Characteristics and examples of and evolutionary relationships among animals in nine phyla sponges cnidarians atworms mollusks annelids nematodes arthropods echinoderms chordates be sure to use the table I handed out in class to help you see the patterns in characteristics 5 Major characteristics of and evolutionary relationships among the classes of chordates invertebrate chordates plus fishes amphibians reptiles birds and mammals You might want to make your own chart that includes features like vertebrae gills limbs type of egg if any distinctive characteristics and examples It ll help you lea1n Remember my of ce hours are TuesThurs 830 1000 aim and Wed 200 300pm

Why people love StudySoup

Jim McGreen Ohio University

"Knowing I can count on the Elite Notetaker in my class allows me to focus on what the professor is saying instead of just scribbling notes the whole time and falling behind."

Jennifer McGill UCSF Med School

"Selling my MCAT study guides and notes has been a great source of side revenue while I'm in school. Some months I'm making over $500! Plus, it makes me happy knowing that I'm helping future med students with their MCAT."

Steve Martinelli UC Los Angeles

"There's no way I would have passed my Organic Chemistry class this semester without the notes and study guides I got from StudySoup."


"Their 'Elite Notetakers' are making over $1,200/month in sales by creating high quality content that helps their classmates in a time of need."
