Why scientists study a hidden Swiss lake to understand Earth's ancient past
In short: Lake Cadagno in the Swiss Alps acts as a living time capsule. By examining its unique chemistry, researchers can study oxygen-averse microorganisms that mirror the conditions of our planet before the Great Oxidation Event.
Lake Cadagno is a meromictic lake located in the Piora Valley. While most life on Earth has evolved to depend on oxygen since the atmosphere and oceans became saturated with the gas, this lake provides a rare environment where ancient, oxygen-averse organisms still thrive.
Because these microorganisms resemble those from Earth's earliest days, the lake serves as a vital model for scientists investigating the planet's biological history prior to the Great Oxidation Event.
