Document Summary
Week 2. 1 life as we define and name it. Learning outcomes: identify differences among domains and kingdoms, identify organisms using a dichotomous key. Homeostasis maintain constant internal environment regardless of the changing external environment. Binomial nomenclature: put organisms into broad groups then organize them further, into more specific groups. People have the innate tendency to put things into groups to organize information in their heads. Aristotle (384 322 b. c. ) viewed living organisms as unchanged (fixed), and arranged organisms, based on their complexity, on a ladder (scale) with human beings on top. Carolus linnaeus (carl von linn ), a swedish botanist (1707 1778), was the founding father of taxonomy the branch of biology devoted to describing, naming species and classifying species (putting them into groups). Linnaeus viewed species as being created independently and separately from one another; he was not thinking about the relationships among different species of organisms.
