What are the key terms? Can you define them in your own words? Why is he trying to communicate this? (causal) How do each of the 3-5 subpoints factor in to the larger goal of the lecture? (they always do) Can you answer all of the questions on the powerpoint? Have you located the concepts to read deeper on in the book? Scientific Method Observation  - Exploration of a subject or activity - View colors, shapes, sizes, etc. - What does the subject do? Is there movement?  Causal Question - Causal question v. descriptive question - Causal – why do peacocks have such showy tail? - Descriptive – where do birds hibernate to in the winter? - A causal question asks what CAUSES certain things to happen, basically what is the  CAUSE? Hypothesis - A prediction that can be tested - A testable observation, a statement that can be tested to validate an experiment  Prediction - A detailed guess of what result the hypothesis will give  - Connects the hypothesis with a specific outcome Results  - Factual data collected from the experiment - Compares actual data with what was predicted  Conclusion - Explanation of results - Restates the hypothesis and if it was correct or not - Proves the prediction to be right or wrong Causation v. Correlation - Correlation, a comparison of two variables can also be positive or negative

- Causation, shows a reason why something is happening through proof from an  experiment - Correlation and causation maybe appear to coincide on a graph but really they only  relate by chance Johnson’s experimental design  -Independent variable, is manipulated in an experiment -Dependant variable, is being measure according to the changes caused by the independent variable Taxonomy: Define what species is: Result of processes that evolve over time Taxonomy: Kingdom: animalia, plantae, protista, fungi (multicellular) Phylum: (example, chordata) Class: mammalia Order: carnivora Family: canidae Genus: canis Species: familiaris (specific binomial nomenclature) Karl von Linné created classification based on physical similarity: morphology He didn’t include historical similarities and ignores variation: need the phylogeny approach Phylogeny: Begins with morphology and DNA analysis: determines how species are similar/divergent Determines historical relationships and creates evolutionary framework  Traces evolutionary pathways and finds common answers Evolutionary theory organizes phylogenetics o Evolution, the  process  = the genetic change in populations over time
