Visually stunning tree of all known life unveiled online

The OneZoom explorer—available at—maps the connections between 2.2 million living species, the closest thing yet to a single view of all species known to science. The interactive tree of life allows users to zoom in to any species and explore its relationships with others, in a seamless visualisation on a single web page. The explorer also includes images of over 85,000 species, plus, where known, their vulnerability to extinction.

Available to all

The OneZoom explorer is configured to work with touchscreens, and the developers have made the software free to download and use by educational organisations such as museums and zoos.

Dr. Rosindell commented: “Two million species can feel like a number too big to visualise, and no museum or zoo can hold all of them! But our tool can help represent all Earth’s species and allow visitors to connect with their plight. We hope that now this project is complete and available, many venues will be interested in using it to complement their existing displays.”

Drs Rosindell and Wong have also set up a OneZoom charity with the aim of using their tree of life to “advance the education of the public in the subjects of evolution, biodiversity and conservation of the variety of life on Earth.”
