In our interactive tree of life you can explore the relationships between 2,235,473 species and wonder at 105,463 images on a single zoomable page. Each leaf represents a different species, and the branches illustrate how these many species evolved from common ancestors over billions of years.
In contemporary usage, tree of life refers to the compilation of comprehensive phylogenetic databases rooted at the last universal common ancestor of life on Earth. Two public databases for the tree of life are TimeTree, for phylogeny and divergence times, and the Open Tree of Life, for phylogeny.
Apr 6, 2018 · The tree of life is used to explain the relationships between the different species on Earth. From microorganisms to trees to fungi and animals, life has evolved through time down countless pathways to provide us with the marvelous present-day collection of different species.
The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history ( phylogeny ).
Apr 11, 2016 · The tree of life is one of the most important organizing principles in biology 1. Gene surveys suggest the existence of an enormous number of branches 2, but even an approximation of the full...
The tree of life, also called a phylogenetic tree, is a graphic tool that biologists use to portray evolutionary relationships among plants, animals and all other forms of life. The tree reveals evolutionary histories: Each "fork in the road," or branching point, indicates a common ancestor splitting into two descendants.

This tree of life helps us understand relationships between organisms. Taxonomy is both an art and a science, with DNA analysis now playing a significant role. Humans are also classified within this system, highlighting our connections to other life forms.
This interactive web resource allows you to follow any branch on the tree of life to find out how scientists hypothesize all the species on Earth (plus some extinct lineages) are related to one another.
Apr 14, 2016 · A universal Tree of Life (TOL) has long been a goal of molecular phylogeneticists, but reticulation at the level of genes and possibly at the levels of cells and species renders any simple interpretation of such a TOL, especially as applied to prokaryotes, problematic. Citation: Doolittle WF, Brunet TDP (2016) What Is the Tree of Life?
