BIOL 102 Lecture Notes - Lecture 19: Rodinia, Paleomagnetism, Chemical Evolution
Document Summary
Fundamental requirements of organism: survival, growth, reproduction. Science: trying to understand the world through observation and experiments. Observation, hypothesis , test, refinement of hypothesis, test again. Experiments types: comparative: compares an result in natural conditions but with different measurable variables, controlled: one variable is manipulated by the investigator, all others are controlled. Manipulated variable on variable outcome of interest effects will be tested. Specific instances are assumed to apply to most or all instances. General conclusion is made from the weight of evidence of many observations/experiments. Conclusion is for a specific case of interest. If all general laws are true then the specifics are true. A set of interrelated, well-tested hypotheses that is supported by a large body of observational and experimental data. Fossil record: where evidence of this history of life comes from. Uses igneous rocks to date , if none then paleomagnetic dating is used. Land masses were concentrated in the topics.
