Bio 103 Lab 11: From simplicity to complexity: homestasis, autonomy ... and randomness

Cells are interacting assemblies of macromolecules, multicellular organisms interacting assemblies of cells, populations and ecosystems interacting assemblies of organisms ... with in each case more complex behavior emerging from interactions among simpler elements. Could one make sense of more sophisticated aspect sof life in these terms, of social behavior, for example, or the meaning and origin of "purposive" behavior? An approach that we'll follow today is to explore computer models like one we looked at at the beginning of the course.

Bio 103, Lab 9: Mendel's Garden Revisited


One central piece of modern biology derived from Darwin's voyage to the Galapagos in the latter part of the 19th century. A second emerged, more or less independently, during the same period and resulted from the work of Gregor Mendel breeding pea plants and carefully observing the results. This work produced the first clear understanding of "laws of inheritance", and remains fundamental to most modern understanding of genetics.

Bio 103, Lab 8: Onself as a Biological Entity. III. Thinking

In the previous two labs in this series, we've discovered that human behavior takes time, in part because it involves things happening successively in several different parts of an individual, that these happenings can be influenced by a variety of external variables but also to varying degrees by internal ones, and that "thinking" may be a relevant internal variable. We have also, hopefully, become more sophisticated at posing questions, collecting observations relevant to them, and interpreting such observations in relation to questions.

In this lab we want to further build on our experiences by investigating "thinking" itself. Is "thinking" also something that takes time? that can be altered by

Bio 103, Lab 7: Oneself as a Biological Entity. II. Reacting


In last week's lab, we noticed that a part of oneself (the heart) was influenced by but not fully under the control of other parts of oneself. In this lab, we want to further develop the idea that oneself consists of an array of parts that interact with one another to give what we observe as behavior.
