Scientists have unveiled a new "tree of life," demonstrating just how the world's 2.3 million species of animals plants, fungi and microbes are connected. The project, involving 11 institutions ...

The bacterial part of the tree of life quickly sprouted new branches, twigs, and leaves. In the 1980s, all known bacteria fit nicely into a dozen major groups, or phyla.

The tree, the most complete of its kind, ... The largest timed molecular phylogenetic tree of life, called a "timetree," to date includes just over 200 primate species, ...

The largest timed molecular phylogenetic tree of life, called a ‘timetree’, to date includes just over 200 primate species, while the largest synthetic timetree, drawing from over 4,000 ...

The finding settles a central question about the evolution of the entire tree of animal life. All animal life is descended from a single common ancestor — a multicellular organism that most ...

Birds are the most diverse land vertebrate on the planet, and now scientists have constructed a complete evolutionary tree of the 11,000 or so known species. This data came from hundreds of ...
