A301 - Dinosaur Evolution
Paleontologists have long been aware of the
hereditary relationships between species and realized
that categorizing them into neat little compartments
was inadequate for their purposes. They
discarded the Linnaean system and replaced it with
phylogenetic systematics, also known as cladistics.
This new system organizes species and groups in
relationship to one another, based on the development
of physical characteristics. This poster represents
the first time that this new system was ever
used to create a pictorial cladogram showing how
dinosaurs evolved over millions of years.
This second edition features a more streamlined
cladogram, making it easier to use.
