A phylogenetic classification system attempts to arrange species into groups based on their evolutionary origins and relationships. It uses a hierarchy in which smaller groups are placed within larger groups, with no overlap between groups. Each group is called a taxon (plural taxa). One hierarchy comprises the taxa: domain, kingdom, phylum, class, order, family, genus and species. Each species is universally identified by a binomial consisting of the name of its genus and species, eg, Homo sapiens. Recall of different taxonomic systems, such as the three domain or five kingdom systems, will not be required. Students should be able to appreciate that advances in immunology and genome sequencing help to clarify evolutionary relationships between organisms.
Here are some videos looking at the evolution of birds, whales and humans - some basic, some quite technical. They are here to give you ideas about what to look at, but you should do some independent research as well as watching them!
