A little known side element to the Open Tree of Life project is the “Edu Tree of Life,” an interactive educational experience to engage the public. Nearing completion, our goal with this website has been to educate young students as well as the general public on topics surrounding evolution and phylogenetic trees. Our approach is to visually inform and engage users with colorful and entertaining animation, interactive features, and contextualization of facts and figures.
Our educational site is composed of three unique, interactive views of the ToL:
1) A “Big Picture” tree provides a zoomed-out timeline perspective of life’s history on earth and explains key elements of the tree of life using a stylized, graphic visualization. This ‘macro’ view presents the evolutionary history of Earth, starting from the creation of our planet and spanning all the way to present day. As the user moves up the timeline, the tree ‘grows’ in front of them revealing historical information; each new screen also offers a detailed explanation of one of several core concepts surrounding evolution. Video explanations containing animations live narrators explain each of these core concepts. Along with the videos, ‘pop-up’ information boxes also offer information.
- A macro View
- Key Concepts
- Timeline of Life
- Chaptered Format/Parallax Scrolling
- Videos and Animation
The core concepts we explore are:
- The Origin of Life
- The Three Domains of Life
- Common Ancestors
- Lateral/Horizontal Gene Transfer & Genes
2) The page titled ““Categorizing Life on Earth” is a mid-sized view of life, a data-driven interactive tree with a focus on the groupings of species (clades). This Tree uses a sampling of data to illustrate hierarchy with a familiar ‘tree’ structure that employs branching lines of evolution. It pulls images from Phylopic and data from EOL for descriptions. A user can expand and contract nodes to view clades they find interesting. Still to come: we are exploring ways to illustrate LGT and are working on connecting nodes back via their common ancestry, so that clicking any two nodes will show you a visualization of how those species are connected through the whole tree of life.
- Mid-sized view of major clades
- Data-driven interactive
- Shows Common Ancestry, Phylogeny and Clades
- Species groupings ending in Clades
3) The “Explore Species” page is our ‘micro view’ of species on Earth. This interactive spinning wheel allows a user to select any of about 180 species to learn about. The 180 species were chosen as exemplary based on many factors: some were chosen for their relative familiarity with the general public, but many were chosen due to specific scientific breakthroughs associated with them. Many were the first species within their field of study to be gene-sequenced, some are keystone species with important evolutionary relatives, and others have strange or unique characteristics worthy of mention.
The information offered for each species includes an image (when available), scientific and common names, the major domain within which the species resides, and then a brief description of the species. This was achieved using the Encyclopedia of Life’s online API, which allowed us to pull information and other resources off of their site to show on ours. As a way of opening an educational portal between the two, any species you click on in the Wheel of Life can also be visited on its parent page at the Encyclopedia of Life, where much more information about all species can be found. We hope that this partnership will prove very fruitful for bringing in casual interest and turning it into a burning passion for evolutionary science and history. Even if we only end up with a few more zoologists, we’ll be happy.
- Micro View
- Exemplary/representative species
- Connects to EoL API, a gateway for further learning
- Catalogue of interesting species.

Put on your quiz hats! We need some good questions!
• Sponges fall within which major group on the tree of life? (animal, plant, bacteria)
• Which are mushrooms more closely related to: (animals, red algae or plants?)
• How many origins of life were there on Earth? (1, 2, 3)
• Which organisms represent the greatest biomass on Earth?
(bacteria and archaea, mammals, fish)
• How many major groups of organisms are represented in a ham sandwich? (1, 2, 3)
• Genes (i.e. portions of genomes) yield the same estimate for the ToL? (Yes, No, Sometimes)
• The top 10 infectious agents on earth appear where on the tree? (bacteria only, in both bacteria and eukaryotes, in both bacterial and archaea)
• Each gene sequenced and analyzed yields the very same answer for the ToL? (Yes, No, Sometimes)You can submit up to three questions with this form, but feel free to submit more by starting a new one!
The absence of a formal reporting standard for phylogenetic analyses is a major impediment for digital access and reuse of published gene trees and species trees. Efforts are underway to develop a standard for Minimal Information About Phylogenetic Analyses (MIAPA). An important part of this process is community input on metadata – what is important for use and evaluation, and what is reasonable to expect from producers of trees?
Results from this survey will inform two efforts: the collection of digital phylogenetic data for Open Tree of Life and the development of a minimum information standard for reporting phylogenetic analyses (MIAPA, http://www.evoio.org/wiki/MIAPA). If you have any questions, please contact Karen Cranston, National Evolutionary Synthesis Center (firstname.lastname@example.org).

The incredibly wonderful thing about audio is that you can continue doing what you’re doing while listening and learning. Here, biologist and leader of our Open Tree of Life project, Dr Karen Cranston (from the National Evolutionary Synthesis Center at Duke University), explains our evolutionary to Bryan Crump from Radio New Zealand. The Open Tree of Life is the first real attempt to draw a single tree of life (as envisioned by evolutionary scientist Charles Darwin) that includes every known species on Earth.

Assembling, Visualizing and Analyzing a Tree of All Life
National Science Foundation grants will bring together what’s known about how species are related
The “Open Tree of Life” is one of three major new scientific projects funded by the NSF.
June 4, 2012
A new initiative aims to build a comprehensive tree of life that brings together everything scientists know about how all species are related, from the tiniest bacteria to the tallest tree.
Researchers are working to provide the infrastructure and computational tools to enable automatic updating of the tree of life, as well as develop the analytical and visualization tools to study it.
Scientists have been building evolutionary trees for more than 150 years, since Charles Darwin drew the first sketches in his notebook.
But despite significant progress in fleshing out the major branches of the tree of life, today there is still no central place where researchers can go to visualize and analyze the entire tree.
Now, thanks to grants totaling $13 million from the National Science Foundation’s (NSF) Assembling, Visualizing, and Analyzing the Tree of Life (AVAToL) program, three teams of scientists plan to make that a reality.
Tree of Life Project Aims for Every Twig and Leaf
By CARL ZIMMER
Published: June 4, 2012
In 1837, Charles Darwin opened a notebook and drew a simple tree with a few branches. Each branch, which he labeled with a letter, represented a species. In that doodle, he captured his newfound realization that species were related, having evolved from a common ancestor. Across the top of the page he wrote, “I think.”
Two decades later Darwin presented a detailed account of the tree of life in “On the Origin of Species.” And much of evolutionary biology since then has been dedicated to illuminating parts of the tree. Using DNA, fossils and other clues, scientists have been able to work out the relationships of many groups of organisms, making rough sketches of the entire tree of life. “Animals and fungi are in one part of the tree, and plants are far away in another part,” said Laura A. Katz, an evolutionary biologist at Smith College.
Now Dr. Katz and a number of other colleagues are doing something new. They are drawing a tree of life that includes every known species. A tree, in other words, with about two million branches.
Researchers aim to assemble the tree of life for all 2 million named species
The resulting tree will be digital, downloadable, continuously updated
Durham, NC — A new initiative aims to build a grand tree of life that brings together everything scientists know about how all living things are related, from the tiniest bacteria to the tallest tree.
Scientists have been building evolutionary trees for more than 150 years, ever since Charles Darwin drew the first sketches in his notebook. But despite significant progress in fleshing out the major branches of the tree of life, today there is still no central place where researchers can go to browse and download the entire tree.
“Where can you go to see their collective results in one resource? The surprising thing is you can’t — at least not yet,” said Dr. Karen Cranston of the National Evolutionary Synthesis Center.
But now, thanks to a three-year, $5.76 million grant from the U.S. National Science Foundation, a team of scientists and developers from ten universities aims to make that a reality.
The tree of life links all biodiversity through a shared evolutionary history. This project will produce the first online, comprehensive first-draft tree of all 1.8 million named species, accessible to both the public and scientific communities. Assembly of the tree will incorporate previously-published results, with strong collaborations between computational and empirical biologists to develop, test and improve methods of data synthesis. This initial tree of life will not be static; instead, we will develop tools for scientists to update and revise the tree as new data come in. Early release of the tree and tools will motivate data sharing and facilitate ongoing synthesis of knowledge.
Biological research of all kinds, including studies of ecological health, environmental change, and human disease, increasingly depends on knowing how species are related to each other. Yet there is no single resource that unites knowledge of the tree of life. Instead, only small parts of the tree are individually available, generally as printed figures in journal articles. This project will provide the global community of scientists who study the tree of life with a means to share and combine their results, and will enable large-scale studies of Earth’s biodiversity. It will also create a resource where students, educators and citizens can go to explore and learn about life’s evolutionary history.
