Circle of life

Guys, I am sharing this fantastic source of information(Zoom it to appreciate it) called tree of life, and guess what? you are free to download it for non-commercial and educational purposes. Make sure you give credit to authors, David M. Hillis and team.

About this tree, in their words:

This tree is from an analysis of small subunit rRNA sequences sampled from about 3,000 species from throughout the Tree of Life. The species were chosen based on their availability, but we attempted to include most of the major groups, sampled very roughly in proportion to the number of known species in each group (although many groups remain over- or under-represented). The number of species represented is approximately the square-root of the number of species thought to exist on Earth (i.e., three thousand out of an estimated nine million species), or about 0.18% of the 1.7 million species that have been formally described and named.
