Yet another example of how much more we have to discover about the natural world - an entirely new branch of the evolutionary tree has been discovered in the Artic Ocean. This is not just a new species, but a lineage of life that has never been seen before - the picobiliphytes.
Superficially these new organisms are very small algae, but their DNA suggest that they are as different from other algae as land plants are from animals. It's exact place on the tree of life and how this discovery may help us learn more about evolution (of eukaryotes in particular) are yet to be determined. Once again, we can see how the the study of biology is constantly pushing forward - just how thick will the AP textbook be 15 years from now?!?!
New Form of Life
