A105 Milestones of Vertebrate Evolution
This incredible poster presents a tremendous amount of information in an easily understandable way.
Along the left edge, the major milestones (physical developments) of vertebrate evolution are shown and
described. The main design is an “Evolution Tree” superimposed over the geological time scale. (See
Eras of Life on page 7.) The milestones are marked on it to show the resulting animal clades. The beginning
and end of each branch shows when they lived; the thickness of the branch indicates their relative
abundance or scarcity during each geological period. 119 species are shown, all in the proper geological
period. This makes it easy to see which animals lived at the same time. Interesting insets explain
everything.

Poster Details |
 |
This exciting new poster provides a
comprehensive overview of vertebrate evolution
in accordance with the new cladistics system,
which it introduces. The most important evolved
characteristics are shown and explained as the
"Milestones of Vertebrate Evolution."
These provide the foundation for grouping
similar animals together into "clades."

The Evolution Tree is superimposed over a geological time
chart. The branches show how milestones resulted in new
groups of animals. The position of the branches shows how
animals are related. The beginning, end and length of each
branch shows when they lived, and, the thickness of branches
provides a symbolic representation of the relative abundance
or scarcity of those animals during each period of
geological time. |

Insets provide a wealth of additional information about
related subjects. These include an introduction to
geological time, the dangers of unchecked evolution, the
impact of mass extinctions, adaptive radiation and how
various types of animals dominated the earth at various
times. The evolution tree dramatically shows the impact of
the mass extinctions and the animals that radiated as a
result of them.
This posters shows around 116 different species
positioned to show the results of evolutionary milestones.
Collectively they provide an incredible overview of the
diversity of prehistoric animals. The linage of each group
can be followed forward or backward in time.
The design
makes it easy to see the mix of animals that lived at
various times.
Dr. Robert
Reisz, vertebrate paleontology at the University of Toronto
is a pioneer in cladistics. He was the consultant on this
poster, along with Alan Kazlev, webmaster of palaeo.com. |

Three poster Set |
| Animal Development, Milestones of Evolution
and our new Animal Kingdom poster are designed to be
used both individually and together. Animal Development
focuses on the invertebrates and Milestones of Vertebrate
Evolution picks up where it leaves off. Both show how
the various clades evolved; Animal Kingdom show the
results. Teachers, students and professionals will find them
to be an invaluable reference.
All are listed on the menu at left. |
