Morning Lectures

9:00 AM Evolutionary Homology versus Sequence Similarity: Darwin to DNA; Combinatorics of Sequence Comparisons, Dot Plots, Two-way and Multiple Sequence Alignments; Gap penalties; Assumptions about mutations - transition versus transversion frequencies.

"Sequence Alignment"

"Similarity is observed; Homology is inferred." How is sequence similarity measured? How do different kinds of "yardsticks" influence our inferences about similarity (parsimony, maximum likelihood, and tree assumptions? Do we employ chemical similarity of amino acyl residues or genetic similarity of notations as criteria? How much do we penalize for gaps? What can be inferred about function from sequence similarity?

"Trees, Ladders, Chains: Reclassifying Life, Recalculating Time"

Theodosious Dobhansky said: "Nothing makes sense except in light of evolution." We will explore using a weaker corollary as a heuristic: "Everything in biology makes more sense in light of evolution." How do we draw evolutionary inferences? How do we test evolutionary hypotheses? How do inform traditional and industrial problems in biology?
