* Mitochondria are organelles thought to be present in all eukaryotic organisms. Their most important function is to produce energy (as ATP molecules). Eukaryotic cells need a lot of energy in order to sustain their metabolism, and as mitochondria produce as much as 90% of the total ATP in the cell, scientists never found an eukaryote without mitochondria…

Until today!

A group of scientists at the university of Prague found a protist that doesn’t have mitochondria at all. This organism live in the guts of small mammals, where there’s few oxygen and lot of food. Such an environment is not very functional for mitochondria, as they need oxygen in order to produce ATP. These organisms probably lost mitochondria during evolution, making them more adapted to live in that environment.
