The
scheme below uses both the old Linnaeus classification system,
as well as some new phylogenic conventions, including the three
domains of life. It is merely intended as a ontology (i.e.,
road map) to use to link to information and pictures of various
categories of fossils. For sure, as genomes, proteomes and gene
function of extant organisms are studied, there will be surprises
and scientific debate, and branching points in the Great Tree
of Life will likely change.

From
the first dawn of life, all organic beings are found to resemble
each other in descending degrees, so they can be classed in
groups under groups.
