Scientists have been saying that life on Earth began in the shallow ocean environment when the chemical elements necessary for life took organic form and the first single-celled organism was formed. A study has pointed to another possibility. The study claims that life on Earth began 4 billion years ago in a volcanic area.
According to the study, this started about four billion years ago. A study published in Nature states that the basis of their claim is that there are signs hidden in a shallow and salty water lake on a volcanic rock in the British Columbia province of Canada, which would indicate when life began.
In the carbonate-rich lake, a Washington University professor and his colleagues found conditions that allowed them to detect signs of the beginning of life. They believe that this could be the place where life began. The research team conducted the study here on the basis of a 1990 report in which information was given about finding a lot of phosphate here.

This lake named Last Chance is only one foot deep. But it contains phosphate in very high quantity. No other lake on Earth has this much phosphate. Phosphate is considered the main element of the basic substances that sustain life. Phosphate is a major element in RNA, DNA and even ATP, the molecule essential for the energy of all forms of life. There was a thousand times more phosphate here than any other ocean or lake, as well as the mineral molomite, which contributes to creating an environment conducive to life.
Last Chance Lake is not four billion years old. It is only 10 thousand years old. But from this, scientists definitely understood what the environment would have been like on the ancient Earth. Researchers say there is every reason to believe that such lakes may have been numerous 4 billion years ago. In such a situation, there would have been more chances for life to flourish there.
