Virus: Riboviria (Early RNA replicators)
~3.7 Billion Years Ago (+/- 100 million)
RNA virus ancestors may trace back to the RNA world, but we can’t prove whether they predate LUCA or arose just after.
RNA-dependent RNA polymerase (RdRp) is ancient. They are found across diverse RNA viruses and likely predate the diversification of modern cells. Some researchers propose RNA viruses may be as old as early cellular life. So Riboviria could have roots near the origin of life itself.
Viruses do not feel. They do not sense. They do not search. They drift until chemistry locks them in place.
And now, a premium bonus.
About 3.7 billion years ago, RNA virus ancestors may trace back to the RNA world, but we can’t prove whether they predate LUCA or arose just after.
