Scientists have discovered a new non-oxygen breathing animal, Researchers from Tel Aviv University (TAU) found an animal without oxygen. The unexpected finding changed one of the assumptions of zoology.
A small parasite, smaller than 10 cells, Henneguya salminicola, lives in salmon muscle. With its development, the animal, which is a myxozoic relative of jellyfish and coral, has stopped breathing and consumed oxygen to produce energy.
Aerobic breathing is thought to be everywhere in animals, but we have now confirmed that it does not exist, researchers say. Our findings show that evolution can go in strange directions. Aerobic breathing is an important source of energy, but we have found animals that have left this critical path. Scientists have discovered a new non-oxygen breathing animal.
Some other organisms such as fungus, amoeba or cilia in the anaerobic environment have lost their ability to breathe from time to time.
New research shows that the same thing can happen to animals, maybe because parasites live in anaerobic environments.
The parasitic anaerobic nature is an accidental discovery. When compiling the genome of the genome, researchers found that it did not enter the mitochondrial genome.
Mitochondria are the strength of cells that trap oxygen to produce energy. Their absence indicates that the animal did not breathe oxygen.
Until the new discovery, there was debate about the possibility for organisms in the animal kingdom to survive in an anaerobic environment.
The assumption that all animals breathe oxygen is based, among other things, on the fact that animals are multi-celled, highly developed organisms that only appear on Earth when oxygen content increases. Scientists have discovered a new non-oxygen breathing animal.
It’s not yet clear how parasites produce energy, researchers say. You can get it from the surrounding fish cells, or there are various types of breathing, e.g. B. Oxygen-free breathing, which usually characterizes anaerobic animal-free organisms.
It is generally believed that organisms become more complex during evolution and that simple unicellular or multicellular organisms are the ancestors of complex organisms, “he concluded. But here, right before us, is an animal whose evolutionary processes are contradictory. Scientists have discovered a new non-oxygen breathing animal.
It lives in an oxygen-free environment, removes unnecessary genes for aerobic breathing and becomes an even simpler organism.
