For example, the lineage for Homo sapiens is:
To the best of my knowledge, the most complete source of information on organismal phylogeny is taxonomy.dat a 100+ Mbyte file available from the European Bioinformatics Institute (EBI).
The taxonomy.dat file lists over 400,000 species, as a taxonomy (i.e., a list with a a parent class assigned to all species). Taxonomy.dat provides a species id number and an id number for the parent class for each taxonomic entry.
Using this information, it is possible to compute the complete classification hierarchy for each of the 400 hundred thousand plus named organisms in taxonomy.dat.
Though there are millions of species of organisms on earth, the taxonomy.dat file is one of the most comprehensive taxonomic references available to scientists.
I have created a web site that allows users to enter the name (scientific name or common name) of any species listed in the EBI's taxonomy file and get back a full listing of the descending phylogenetic class hierarchy for the species.
It is available at:
The same search box is available here:
After entering the full name of a species into the input box, and pressing the submit button, you get the taxonomic entry for the organism, followed by its phylogenetic hierarchy.
If you can't think of an organism to enter in the query box (above), here are some suggestions:

Science is not a collection of facts. Science is what facts teach us; what we can learn about our universe, and ourselves, by deductive thinking. From observations of the night sky, made without the aid of telescopes, we can deduce that the universe is expanding, that the universe is not infinitely old, and why black holes exist. Without resorting to experimentation or mathematical analysis, we can deduce that gravity is a curvature in space-time, that the particles that compose light have no mass, that there is a theoretical limit to the number of different elements in the universe, and that the earth is billions of years old. Likewise, simple observations on animals tell us much about the migration of continents, the evolutionary relationships among classes of animals, why the nuclei of cells contain our genetic material, why certain animals are long-lived, why the gestation period of humans is 9 months, and why some diseases are rare and other diseases are common. In “Armchair Science”, the reader is confronted with 129 scientific mysteries, in cosmology, particle physics, chemistry, biology, and medicine. Beginning with simple observations, step-by-step analyses guide the reader toward solutions that are sometimes startling, and always entertaining. “Armchair Science” is written for general readers who are curious about science, and who want to sharpen their deductive skills.
