here are some suggestions:

Phylogeny is the ancestral lineage for an organism, begining at the
species level and descending to the primordial organism from which
all extant species evolved.
For example, the lineage for Homo sapiens is:
Homo sapiens
Homo
Homo/Pan/Gorilla group
Hominidae
Hominoidea
Catarrhini
Simiiformes
Haplorrhini
Primates
Euarchontoglires
Eutheria
Theria
Mammalia
Amniota
Tetrapoda
Sarcopterygii
Euteleostomi
Teleostomi
Gnathostomata
Vertebrata
Craniata
Chordata
Deuterostomia
Coelomata
Bilateria
Eumetazoa
Metazoa
Fungi/Metazoa group
Eukaryota
cellular organisms
An excellent, public source of information on
organismal phylogeny is taxonomy.dat a 100+ Mbyte file available
from the European Bioinformatics Institute.
The taxonomy.dat file lists over 400,000 species, as a taxonomy (i.e., assigning
a parent class to every specie), providing
a species id number and an id number for the parent class.
Using this information, it is possible to compute the complete
classification hierarchy for each of the 400 hundred thousand plus
named organism in taxonomy.dat
By entering the full name of any organism (included in taxonomy.dat)
in the input box, and pressing the submit button, you will get the
taxonomic entry for the organism, followed by its phylogenetic
hierarchy.
