Did life on Earth begin in Saudi Arabia 3.48 billion years ago?

<p style=";text-align:left;direction:ltr">Weather of Arabia - In a research achievement and scientific opportunity that specialists described as “unprecedented,” a new study revealed that life on Earth may have originated in Saudi Arabia 3.48 billion years ago, which raises important questions about the beginning of life on our planet.</p><h2 style=";text-align:left;direction:ltr"> Discovery details</h2><ul style=";text-align:left;direction:ltr"><li style=";text-align:left;direction:ltr"> Location: Shibara Island in the Red Sea, Saudi Arabia.</li><li style=";text-align:left;direction:ltr"> Discovery: Living stromatolites (organic sedimentary structure) that represent the first discovery of living shallow marine stromatolites in the Middle East.</li><li style=";text-align:left;direction:ltr"> Journal: The study was published in the Journal of Geology.</li></ul><p style=";text-align:left;direction:ltr"></p><h2 style=";text-align:left;direction:ltr"> Did life on Earth begin in Saudi Arabia?</h2><p style=";text-align:left;direction:ltr"> Specialists define &quot;stromatolites&quot; as layered sedimentary formations resulting from the activity of microorganisms, especially cyanobacteria.
