Every species sits somewhere on the tree of life, and somewhere on a scale of extinction risk. The Tree of Life puts both on the same picture.
Using IUCN Red List data and the animal phylogeny, I drew the whole tree shaded by how threatened each branch is, made it zoomable down to individual clades, and mapped where threatened species actually concentrate on the planet. Each figure below is interactive. Hover, zoom, and pan.
The animal tree of life drawn as a radial dendrogram, every branch shaded by extinction risk. The deeper the red, the more threatened the lineage.
The same tree, made explorable. Click a clade to dive into it; color encodes that clade’s mean extinction risk, so you can see where risk clusters.
Where threatened animals concentrate. A world map of species counts across the vulnerable, endangered, and critically endangered categories.
Extinction risk read across the major branches of the animal tree, so you can compare how threat is distributed between taxonomic groups.
