Connecting millions of pieces
Creating the entire tree of life is like completing a jigsaw puzzle with more than two million pieces. And to make it even harder; the illustration of how the solved puzzle would look like is missing.
No one knows precisely how all pieces are related.
This disparity is unmistakably demonstrated by disagreements between evolutionary biologists about how certain species and branches are linked together. Throughout the years they have created a large variety of trees with specific groups of species that contradict each other. For example, one researcher maintains that species A is the closest living relative of species B, but another scientist thinks that species C is actually most closely related to B. (more…)
Is it a plant? Or is it a monkey?
It should not be hard to recognize the differences between furry night monkeys and the bright yellow flowers of golden peas. But they have something peculiar in common that leads to some confusion once in while: their name. Both genera are officially known as Aotus.
There are about two million known species on the planet, so it should not come to a surprise that scientists accidentally have given certain species, or groups of species, similar names. For instance, Proboscidea is considered an order of elephants, but it is also the name for the genus of devil’s claws. Other examples include Myrmecia pyriformis (insect and green algae), Ficus elegans (mollusc and plant), Ormosia nobilis (insect and plant), and Trigonidium grande (orchid and katydid).
Across disciplinary boundaries
What do a fungal evolutionary biologist and a computer scientist have in common?
It is usually easier to name a long list of differences, but that does not mean that those scholars are investigating different issues all the time. They may be very much interested in the same problems, yet apply different perspectives and methods in search for answers.
Those scientists could continuously work on their individual research projects for may years. However, in some cases only an interdisciplinary collaboration leads to a solution. The investigators of the Open Tree of Life project hope this will be the case for them as well. Their goal: creating a tree of life that includes all 1.9 million known species. (more…)
