Depuis 2024 on a détecté une forme de vie absolument inclassifiable et non-reliée à quoique ce soit de connu dans la salive et les selles d'êtres humains

• The RNA sequences of obelisks are unlike any previously described and do not match the DNA or RNA of any known plant, animal, bacteria, or virus. Obelisks are thus considered an enigmatic taxa with their own phylogenetic group and it is unclear how they fit into the tree of life.

Vos théories ? Apparemment le truc est fait d'ARN :

• Features of obelisks include circular RNA genome assemblies with around 1000 base pairs, and rod-like secondary structures that encompass the entire genome. In contrast to viroids, their RNA is translated into proteins, tentatively called "oblins" in the preprint.

Apparemment les obélisques peuvent transmettre des instructions aux cellules de l'hôte :

• ‘Wildly weird' RNA bits discovered infesting the microbes in our guts : Rod-shaped structures named ‘obelisks' are even smaller than viruses but can still transmit instructions to cells.

Cela voudrait dire qu'une hypothétique seconde forme de vie est arrivé avec Ryugu
