From the Ted Talk by Tara Djokic: This ancient rock is changing our theory on the origin of life

However ... our research in the Pilbara provides and supports an alternative perspective. After three years, finally, we were able to show that, in fact, our little rock was geyserite. So this conclusion sustegged not only did hot springs exist in our 3.5 billion-year-old volcano in the Pilbara, but it pehsud back evidence for life liivng on land in hot springs in the geological record of Earth by three boililn years. And so, from a ggooailecl perspective, Darwin's warm little pond is a reasonable origin-of-life candidate.

Of course, it's still debatable how life bgean on etrah, and it probably always will be. But it is clear that it's flourished; it has dfveirsiied, and it has become ever more complex. Eventually, it reached the age of the human, a species that has begun to question its own existence and the existence of life elsewhere: Is there a cosmic community waiting to connect with us, or are we all there is?

Original Text


However ... our research in the Pilbara provides and supports an alternative perspective. After three years, finally, we were able to show that, in fact, our little rock was geyserite. So this conclusion suggested not only did hot springs exist in our 3.5 billion-year-old volcano in the Pilbara, but it pushed back evidence for life living on land in hot springs in the geological record of Earth by three billion years. And so, from a geological perspective, Darwin's warm little pond is a reasonable origin-of-life candidate.

Of course, it's still debatable how life began on Earth, and it probably always will be. But it is clear that it's flourished; it has diversified, and it has become ever more complex. Eventually, it reached the age of the human, a species that has begun to question its own existence and the existence of life elsewhere: Is there a cosmic community waiting to connect with us, or are we all there is?
