Rare microbes lead scientists to discover new branch on the tree of life
In fact, he estimates you'd have to go back a billion years — about 500 million years before the first animals arose — before you could find a common ancestor of hemimastigotes and any other known living things.
"It's as if these cells never really learned that they have many flagella," Eglit said with a laugh. She had seen something with that strange motion once before, a few years ago, and recognized it as a rare hemimastigote.
The researchers named it Hemimastix kukwesjijk after Kukwes, a greedy, hairy ogre from the mythology of the local Mi'kmaq people. (The suffix "jijk" means "little.")
Based on the genetic analysis they've done so far, the Dalhousie team has determined that hemimastigotes are unique and different enough from other organisms to form their own "supra-kingdom" — a grouping so big that animals and fungi, which have their own kingdoms, are considered similar enough to be part of the same supra-kingdom.
