Scientists recently retrieved mantle rocks from beneath the Atlantic seafloor, which could help shed light on the early origins of life on Earth. The mantle rocks were obtained from an area where the crust is thin, allowing scientists to study the deep workings of the Earth and the tectonic processes that shape our planet. The rocks may also hold clues to the chemistry that led to the formation of organic compounds vital for life. The expedition uncovered high concentrations of hydrogen gas, which could power abiotic reactions and potentially provide insights into the chemistry of prebiotic life.
