Document Summary
Key concepts in chapter 1: key developments, (1) cell theory, (2) the theory of evolution by natural selection, both of these developments are unified by the concepts of ancestry and descent. Evolutionary relationships among species and among cells can be represented by phylogenetic trees: how does one do biology (ask questions, generate hypotheses and predictions, and conduct experiments to test them) The cell theory: a cell is a highly organized compartment bounded by a plasma membrane that contains concentrated chemicals in an aqueous solution. In general, cells contain molecular information (dna) that encodes their physical attributes (through some cells loose their dna: cells have a boundary between them and the environment, cells have the ability to harness materials and/or energy. Implications of the cell theory: because all cells come from pre-existing cells, all individuals in a population of a single- celled organisms are related by a common ancestry.
