Molecular Clock
the average rate at which a species’ genome accumulates mutations, used to measure their evolutionary divergence and in other calculations
Cladistics
a method of classification of animals and plants according to the proportion of measurable characteristics that they have in common.
Cladogram
a branching diagram showing the cladistic relationship between a number of species.
Archaea
Bacteria
Protists
of eukaryotic organisms that are unicellular and sometimes colonial or less often multicellular and that typically include the protozoans, most algae, and often some fungi
Fungus
any of a group of unicellular, multicellular, or syncytial spore-producing organisms feeding on organic matter, including molds, yeast, mushrooms, and toadstools.
