Find living specimens of the oldest forms of life on Earth

<p style=";text-align:left;direction:ltr"><strong>Weather of Arabia</strong> - Researchers found live samples of the oldest microbes on Earth (stromatolites), which are the oldest evidence of life on Earth, within a World Heritage area in Tasmania, Australia <span>.</span></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> Sedimentary rocks that contain microbes date back about 3.7 billion years, and are considered part of the solution to the puzzle that constitutes the geological history of the Earth, thanks to the layers of cyanobacteria consisting of a biofilm (a thin biofilm). The gathering of stromatolite layers led to the formation of rock structures <span>.</span></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> The new discovery may help find living stromatolites in Tasmania for the first time, researchers to understand why these living specimens spread and grow for millions of years on Earth, only to disappear after that and a few of them remain in &quot;exceptional places <span>&quot;.</span></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> It is reported that modern living examples of sedimentary rocks are rare.
