BIOL 111 Lecture Notes - Lecture 2: Phylogenetic Tree, Ardipithecus, Australopithecus
Document Summary
Learning outcomes: interpret a phylogenetic tree to identify the degree of relatedness, identify different characteristics of organisms that are useful for constructing phylogenetic trees. Reminders: next reading quiz for week 3 due monday sept 17th (see syllabus for pages) Used to describe relatedness between organisms from an evolutionary standpoint. Optional field trips sat sept 15th and sunday sept 16th from noon-2pm 16th ave and sasamat. Digital collection and classification due friday sept 21st. Darwin"s tree of life from origin of the species fyi: this is the only figure in his whole book. His idea was that all living things have diverged from a shared common ancestor. All phylogenetic trees are based on this idea. Characteristics for comparison and group are chosen for their evolutionary significance: morphological similarities. Need to be cautious of analogous structures (with similar function but from different origins) eg fins.
