The study of
prehistoric life is at the forefront of life science studies,
natural history museum interpretive programs, and popular
culture, but there has never been any comprehensive overview of
the evolutionary steps in any media. This remarkable poster
fills that need. It contains a wealth of information and
presents it in a very simple way, making it easy to understand.
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
main design is an "Evolution Tree," which is a stylized cladogram. It shows and
identifies all of the major clades. The "tree" design shows how
each branched off from earlier ones and other relationships.
Each of the milestones is predominately marked on the tree as
they are the basis for the most important clades.
amniotic egg was one of the most important developments
in vertebrate evolution. Eggs have a semi-permeable
shell that protects the embryo from drying out. The yolk
provides a food source. It was this self-contained means
of protecting and feeding the unborn that permitted
tetrapods (the first land animals) to live in
environments far from water. Amniotes are a major clade.
It includes all reptiles, mammals and birds.
