The lake nearly 3 billion years can contain alien life
Researchers found evidence of alien life in the oldest lake in the world deep underground in northern Ontario, Canada.
The microbial life form in the lake lies at a depth of 2.4 km inside the Kidd mine in northern Ontario, Canada, completely different from the terrestrial life, according to a study published on October 27 in Nature Communications. The lake was discovered in 2013 and is estimated to be separated from the earth 2.64 billion years ago, almost half of the Earth's life.
The research team at the University of Toronto, Canada, points out that water in the lake has a system of self-supporting life , meaning that foreign life evolved underwater, isolated from life on the ground, without contact with the light. sunlight or oxygen in the atmosphere for billions of years. They also found indirect evidence of microbial life forms that could not be determined. Most likely the bacterial population evolves in parallel with life on the surface. The same thing can happen on Mars.

Researchers have found that bacteria that live in the same water environment flow through ancient rock slabs in the ground in South Africa. But the lake in Canada is separated from the ground for 10 times longer, enough for strange life forms to evolve .
Many life on Earth takes energy from chemical reactions that push electrons from one place to another. But some types of bacteria have evolved in the other direction. They use hydrogen gas as a source of electrons and a form of dissolved sulfur called sulphate becomes the destination of electrons.
Researchers know in the hydrogen-rich ancient lake of Canada and new research shows that the amount of sulphate in the lake is enough to sustain life. Sulfur exists in pyrite in the surrounding rock and is broken by natural radioactivity of the rock and dissolved in water. According to the team's results, life began to exist since the lake was isolated, forming a long-lived environment.
The team calculated a 100 to 1,000 times lower sulfur content in the lake than domestic water, indicating that low-evolution microorganisms existed in water and used up sulphites, according to University of Long Li. Alberta said. The finding has important implications in helping scientists determine the direction of finding life forms on Earth and other planets.
"Because ancient Earth geology is similar to the current Mars, we need to look at the long-term minerals in the country that are now a few kilometers below the surface, which can produce the necessary energy source for microbes. bacteria, " Li said. "I do not dare to claim that bacteria exist but the lake has the necessary conditions for life on Mars."
