By clicking on the above picture, you will watch a simplified representation of the phylogenetic tree of birds.
This pages have been done with the software Inxight Star Tree Studio and the information found on the regretted website http://phylogeny.arizona.edu/tree/phylogeny.html. It is not the aim of this presentation to introduce the complete view of the history of birds. My goal is to show a simple view of the slow evolution of the wildlife, from the first cells to the more developped pluri-cellular animals.

To browse these pages, click-slide to open the branches of the tree. Left click centers the square selected on the page. Most of the squares are active, and lead by double-click to a page describing the clade selected on the website of the Museum of Paléontology of the University of California, Berkeley : http://www.ucmp.berkeley.edu/help/taxaform.html. The squares*synapsida* and *reptilia* link to the following of the phylogenetic tree.
