What is the tree of life?
The tree of life shows how all life on earth is related. Each leaf represents a different species. The branches show how these many species evolved from common ancestors over billions of years. In our interactive tree of life you can explore the relationships between 732,697 species and wonder at 68 images on a single zoomable page.

Biodiversity and Conservation...
We want to help everyone appreciate biodiversity and the need to conserve it.
Red leaves on our tree of life show species known to be under threat of extinction.
Green leaves are either okay for now but might be nearly threatened.
Most leaves are grey meaning that it's not known how threatened they are.
