Evolution is a powerful and central theme that unifies the life sciences. In this course, emphasis is placed on microevolutionary mechanisms of change, and their connection to large-scale macroevolutionary patterns and diversity. Through lectures and readings from the primary literature, we will study genetic drift and gene flow, natural selection and adaptation, molecular evolution, speciation, the evolution of sex and sexual selection, life history evolution, and inference and interpretation of evolutionary relationships. Three hours of lecture and one hour of discussion each week.

(Offered  as BIOL 291 and BCBP 291)  An analysis of the structure and function of cells in plants, animals, and bacteria. Topics to be discussed include the cell surface and membranes, cytoskeletal elements and motility, cytoplasmic organelles and bioenergetics, the interphase nucleus and chromosomes, mitosis, meiosis, and cell cycle regulation. Four classroom hours and three hours of laboratory per week.

Requisite: BIOL 191 and completion of, or concurrent registration in, CHEM 161.  Limited to 24 students. Spring semester. Professor Graf.

Independent reading or research courses. Full course as arranged. Does not normally count toward the major.

Fall and spring semesters.

How can a single cell, the fertilized egg, give rise to all the specialized cells of an adult? What gives rise to biological form?  What is the molecular logic of the pathways that progressively refine cellular identities? How do cells "talk" to one another so as to coordinate their behaviors as embryos develop form and function? How can parts of an organism be regenerated with only the appropriate regions remade, structured identically to the missing ones? How does a stem cell differ from a non-stem cell? How can genetically identical organisms be cloned?
