So far, scientists have identified three domains of life: prokaryotes, eukaryotes and bacteria & archaea. A recent study however in Marseille School of Medicine, suggests that there may be a fourth one. The “Mimivirus”, named, or should I say, nicknamed, as such due to its mimicking abilities. The Mimivirus, more formally known as the giant virus, is an organism that inhabits amoebae. Viruses are known to be dependent beings, relying on living organisms to synthesize their proteins. According to genetic analysis however, it was found that Mimivirus has genes for protein translation, DNA repair enzymes and other proteins. As such, Mimivirus seems to support that a fourth family emerged 4 billion years ago.
