Cell theory (all organisms are made of cells and that all cells come fro preexisting cells) natural selection (species change through time b/c individuals with certain heritable traits produce more offspring than others) Phylogenetic tree - graphical representation of the evolutionary relationships among species. Estimated by analyzing similarities and differences in traits. Theory is an explanation for a very general class of phenomena or observations. Cell theory and theory of evolution focus on what organisms are made of and where they came from. Robert hooke used a crude microscope to examine the structure of a cork from an oak tree - saw cells. Anton van leeuwenhoek developed a much more powerful microscope and was the fist to view single-celled animalcules in pond water.
