Long Durational Natural Phenomenon
Existence of Siberian Actinobacteria
Duration: Approximately 400,000-600,000 years
The Siberian Actinobacteria has existed for approximately 400,000-600,000 years, making it the oldest living organism on planet Earth.
They are a group of Gram-positive bacteria. Most are found in the soil, and they include some of the most common soil life, playing important roles in decomposition and humus formation. Some form branching filaments, which somewhat resemble the mycelia of the unrelated fungi, among which they were originally classified as the Actinomycetes. All of these bacteria are aerobic and a few forms are pathogens, such as Mycobacterium. Some of the bacteria are thermophilic. Siberian Actinobacteria are not dormant or frozen but actually has been alive and slowly growing for a half a million years.
