Paul Andersen describes microevolution and macroevolution in the stickleback fish of Loberg Lake. He describes how anadramous fish repopulated the lake after poisoning and adapted to the new environment through natural selection. He also explains how reproductive isolation has appeared in fish that have diverged only a few decades in the past.

This course will introduce you to a general overview of the biological world. Important concepts will be reinforced and expanded upon through completion of weekly laboratory activities and homework assignments. Upon successful conclusion of the course, students will be able to do the following: Describe the nature of science, including its methods and its limitations; Describe the basic methodology of doing science and the scientific method; Use the scientific method to study everyday situations as well as in laboratory/field investigations; Identify, describe, and explain at a rudimentary level and present examples of, the characteristics common to all living things; Explain that living organisms are composed of molecules which interact in a variety of different chemical reactions necessary to sustain life; Explain that living organisms are comprised of one or more cells and are classified as prokaryotic or eukaryotic based on cellular characteristics; Describe the hereditary information possessed by living and explain how that information determines the cellular characteristics and functions (including basic Mendelian genetics); Explain and describe, with examples, the diversity of life, at different levels (basic molecular to ecological) and how it is hierarchically organized into systems; Explain how evolution by natural selection occurs, and describe the evidence that supports the theory of evolution; and more.

Paul Andersen explains how organisms are able to regulate their internal body temperature (or not). He starts with a brief description conduction, convection, radiation and metabolism. He contrasts ectotherms and endotherms. He also explains how endotherms use negative feedback loops to regulate internal body temperature.

Paul Andersen starts with a brief description of the history of life. He then discusses the seven characteristics of life and why viruses are not alive. He then describes the three domains in the current classification system and explains why eukaryotes are more closely related to members of the Archaea domain.

Paul Andersen describes how cells move materials across the cell membrane. All movement can be classified as passive or active. Passive transport, like diffusion, requires no energy as particles move along their gradient. Active transport requires additional energy as particles move against their gradient.
