Help!

Wanted: All your favorite trees

With eleven investigators, the Open Tree of Life project is already a large-scale research endeavor. But that does not mean that they can add all 1.9 million known species to a database by themselves. In fact, they are looking for help.

A lot of help.

The main goal of the project is to merge all existing phylogenetic trees in one overarching tree of life. In the past few months, the researchers have been working on software applications to make it possible to store all known species and, more important, to specify how they are all linked to each other in evolutionary terms.

Quiz time!

Dear Colleagues,

Put on your quiz hats! We need some good questions!

As our team works to build an Open Tree of Life for professionals we are also working on a educational version of the tree for the everyone else, meaning educators, students, and the public in general.This public site will have a FUN QUIZ to test people’s knowledge of evolution, and we need questions for it!

SUBMIT YOUR QUESTIONS HERE

SAMPLE QUESTIONS:
Easy:
• 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)
Medium:
• 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)
Expert:
• 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!
