Panspermia {explanation/theory on the origins of life/Central Dogma on the planet}{Comes from another planet/Mars is also acceptable}{Innoculates the earth with the replicating system/Components of the Central Dogma} Convergent evolution {Organism have a structure/something that has a similar function}{but the animals/organisms are not related to each other/ they don’t descend from a common ancestor}{results in homoplasy/analogous} {ex. The one in class – there may be others wing of an insect and other winged vertebrates, wing of bat and bird (don’t share same ancestor, wing of pterodactyl and others etc. Any pair from the winged groups of insects, flying reptiles (pterodactyls), birds and bats} First two points Must be there either of the last two to give the total of three points. Kingdom Plantae {Multicellular eukaryote organism will appear but if it is there both must be there for the full point – in part because this also applies to fungi and plants}{Cell walls made of cellulose}{Autotrophic/able to captures sun’s energy} Archean eon {3.8 – 2.5 Billion years ago}{Period on earth when anaerobic bacteri are the only life form/it is important that they identify that these are bacteria that do not use oxygen for life’s process }{ends with the appearance of and accumulation of oxygen } Page 2 of 5 BIO1130 Midterm Examination – October 1, 2011 STUDENT NUMBER:_______________________________ Don’t enter your name. 18 pts Part 2: Fill in the missing word, or provide the one word answer in the space provided at the end of the sentence.

The unknown specimen under the microscope has those cnidocytes so it is a jellyfish. This is an example of what type of Deductive thinking or reasoning. ______________________ Common Era 2.8 In dates that include BCE, what the CE refers to (two words). ______________________ Testing 2.9 Both a theory and a hypothesis must be able to withstand this. ______________________ 2.10 The science of the scientific revolution studied mostly these types of Inanimate objects. ______________________ 2.11 This philosophy on living things saw them as being made up of small Physacalists machines. ______________________ 2.12 Historical narratives are often associated with this type of science. Natural ____________________ 2.13 Greeks such as Plato and Aristotle all believed that organisms were unique and unaltered Essentialism types, a philosophy given this name. ______________________ 2.14 When a scientist tests a hypothesis they often use the logic of "If this is altered or changed then this should happen" in their design. This if/then statement is a form Prediction of this." ______________________ Page 3 of 5 BIO1130 Midterm Examination – October 1, 2011 STUDENT NUMBER:_______________________________ Don’t enter your name. 2.15 Naturalist thinking begins with these philosophers in Greek 400 BCE. ______________________ 2.16 Your text book is an example of this type of scientific literature.

Any two of the following for two points each – it is essential that the example they give is explained and not just mentioned. Evidence 1: {Comparative anatomy} with an explanation {similar looking things but they must be homologous and an example of homology} Evidence 2: {Comparative embryology} with and explanation {In class we discussed the similarity that appears in the developmental stages of the closely related species – the classic being the vertebrate embryology} Evidence 3: {Vestigial structures} with an explanation {We used goose bumbs, nictating membrane, and appendix – there may be others} Evidence 4: {Biogeography} with an explanation {As organisms are isolated they may change even though they have a common ancestor – examples Australian fauna of Marsupials compared to mammals elsewhere and yet the two are related} Evidence 5: {Molecules-Molecular evolution} with an explanation {The more similarity in an amino acid sequence/DNA sequence the more similar and must have common ancestor, mentioned in class cytochrome C rRNA} 3.2 Scientists in the 18th and early 19th century challenged the Scala naturae. Choose two scientists and briefly describe the evidence that challenged the long held belief. {What about the Scala Naturae – that the time frame was short – since Oct 23 4004BCE and that organisms never changed or modified – this may not be stated directly but it this point is awarded if both are mentioned in the answer} Any two of these Scientist 1: {Georges-Louis Leclerc, Comte de Buffon} {studies in biography showed that animals changed in their form aas the moved away from where they first appeared It is not enough to say Biogeography there must be an explanation to show how biogeography creates species changes} Scientis 2: {Cuvier} {Studies in extinction showed that there were animals that existed in the past that are not here now – Irish Elk and Mammoth may appear in the answer but they must make the link to change Scientist 3: {Charles Lyell} {Geologist whose work on stratigraphy lead to the conclusion that the world is much older than the time frame suggested in the Scala} Page 5 of 5 ...
