Learning outcomes: being able to recognize evolution when you see one, explain how natural selection acts on individuals to shape the characteristics of populations, identify, describe and understand different mechanisms underlying evolution. Reminder: please evaluate your instructor"s teaching effectiveness in this course. The geek philosopher plato thought that living organisms were fixed. Linnaeus collected type specimens and classified organisms in the hierarchy of kingdoms, phyla, classes, orders, families, genera, and species. They ignored variation among individuals in a species and believe that organisms were unchanged and considered variations in individuals that deviate from the perfect type were due to imperfect environments and conditions of this world. Many scientists in early 19th century did not believe that species would go extinct. They thought organisms not found but whose fossils exist were in unexplored regions of the world. Commonly thoughts regarding organisms in the 19th century: organisms were fixed and unchanged; the existing ones do not disappear and no new ones appear.
