Document Summary
Bio1070: levels of biological organization & diversity among species. Levels of biological organization: the system that biologists use to classify species re ects this nested hierarchy, as one moves up the hierarchy the categories become more and more general and include more and more lower-level categories. In particular, dr. zanatta and his students use microsatellites regions of the genome that do not code for proteins and vary widely in quantity among individuals to study variation that is invisible to the eye. Disparity: abundance (number of individuals) among mussels, diversity (number of species) in different areas, disparity refers to how physically different those species are from each other. Tree thinking: phylogenetic trees are the most direct representation of the principle of common ancestry the very core of evolutionary theory and thus they must nd a more prominent place in the general public"s understanding of evolution.
