Uncovering the mysterious origins of life on Earth has captivated scientists for centuries. Were the building blocks of life brought here from outer space or were they present on Earth all along? A groundbreaking new paper published in Science Advances, along with an intriguing article in The Conversation, dares to challenge the conventional wisdom by proposing that life’s origins may have been right here on Earth from the very beginning.
The study delves into the presence of volatile elements such as carbon, hydrogen, nitrogen, and chalcogens on Earth, which are crucial for the formation of life. These elements, including sulfur, selenium, and tellurium, are known to evaporate more easily than other elements, making their existence at the earliest stages of Earth’s development a fascinating subject of inquiry.

At the heart of the debate lies the late veneer theory, which posits that volatile-rich bodies like meteorites, asteroids, and comets delivered these essential elements to Earth’s surface after its core was formed. However, the new research challenges this theory by suggesting that the essential elements for life were actually present within Earth since its earliest days.
Uncovering this hidden truth could shed light on the origin of water on Earth and offer a deeper understanding of the fundamental processes that led to the emergence of life on our planet. As scientists continue to unravel these mysteries, the implications of this research are truly mind-boggling.
