This is an especially
important poster because it presents the new Sibley-Ahlquist bird
classification system. Based on recent DNA studies, it uses
cladistics to reconstruct the evolutionary family tree. Who would
have thought that flamingos, eagles and penguins would end up in the
same biological clade? However, this revolutionary new system has
been widely accepted by North American ornithologists and has made
the traditional bird classification system obsolete.
Although these are true clades, they largely correspond to the
earlier orders. The scientific community continues to use the order
names, which are cited on the poster.
This is a truly beautiful poster, one greatly appreciated by bird
lovers. It certainly enhances the decor of their home or office. Yet
it presents information that has even greater value. All the bird
clades are explored and all of the many classification changes
resulting from the transition from orders to clades are explained.
This information has never before been published in such a concise
and convenient form, making this poster an essential reference to
anyone seriously interested in birds. |
