Document Summary
Chapter one biology and the tree of life. The cell theory and theory of evolution by natural election are unified by ancestry and descent. Evolutionary relationships can be represented by phylogenetic trees. Cell highly organized compartment bounded by plasma membrane containing concentrated chemicals in an aqueous solution. Cell theory all organisms are made of cells and all cells come from pre-existing cells: all cells are descended from a progenitor cell the zygote. Prediction something measurable and must be correct if the hypothesis is correct. Louis pasteur designed an experiment to test if cells arose spontaneously or if they were the result of pre-existing cells. Since all cells come from pre-existing cells, all organism are related by common ancestry, even multi-cellular organisms. Darwin (studied in the galapagos) and wallace (studied in south east asia) proposed that all species are related by common ancestry; they also proposed that the characteristics of a species can be modified from generation to generation.
