Through this mechanism, energy is transferred to cells, which can use it for multiple purposes — for instance, to burn food.Now, researchers at Tel Aviv University (TAU) have discovered a non-oxygen breathing animal, which significantly changes one of science’s assumptions about the animal world — that all animals use aerobic respiration and therefore, oxygen.It also challenges what may be generally thought of as evolution in organisms — that they become more complex as they evolve. Mitochondria is the “powerhouse” of the cell, which captures oxygen to make energy — its absence in the H. salminicola genome indicates that the parasite does not breathe oxygen. According to Klaus Schallie, Molluscan Shellfish Program Specialist with the Canadian Food Inspection Agency, "Henneguya salminicola is found in southern B.C.

An animal this gobsmacking naturally presents more questions than it does answers. One of the researchers saw that it did not have a mitochondrial genome. But the environment inside its fish host is largely devoid of oxygen, so for the parasite to survive, it "breathes" without oxygen at all.
Henneguya salminicola no es nuevo, es un parásito común del salmón y parte de la misma familia que los corales y las medusas, pero su genoma acaba de ser mapeado.
"Puede estar extrayéndolo de las células de peces circundantes, o puede tener un tipo diferente de respiración, como la respiración libre de oxígeno, que típicamente caracteriza a los organismos anaerobios no animales".Agregó: “En general, se cree que durante la evolución, los organismos se vuelven cada vez más complejos, y que los organismos simples unicelulares son los ancestros de los organismos complejos”.El descubrimiento podría cambiar la búsqueda de vida en otros mundos, ya que significa que la vida podría sobrevivir en entornos mucho más diversos.Esto podría incluir en Marte e incluso debajo de las superficies heladas de las lunas de Saturno, Júpiter y Neptuno, aunque los astrobiólogos ya están buscando en esos lugares vida extraterrestre.Eso incluye múltiples misiones al Planeta Rojo que se lanzarán este año y que verán aterrizadores desplegados en el planeta para buscar signos de vida antigua en el suelo.Escríbenos y recibe las últimas noticias en tu celular It's pretty epic stuff for such a diminutive creature.
