A rock that might hold the oldest form of complex life on Earth

Erica stumbled upon a rock a decade ago that may contain the oldest form of complex life on Earth. The discovery suggests that the rock, found in Western Australia, holds evidence of a 3.5-billion-year-old microbial ecosystem. This finding challenges previous beliefs about the timeline of when life forms evolved on our planet. Scientists are intrigued by the potential insights this discovery could provide into the early stages of life on Earth and how organisms developed in ancient times. Further research and analysis of the rock and its contents are underway to unlock more secrets about the Earth's early history and the origins of complex life forms.

The origin of life remains a profound mystery. The more we investigate, the further we push back its beginnings, suggesting that we may eventually need to search beyond Earth for answers. Since the Miller-Urey experiment, which successfully synthesized amino acids, we have made little progress in understanding the exact processes that led to the emergence of life. How were RNA and DNA formed? How did the first cell come together? What were the necessary timelines, energy sources, and chemical conditions? Is Earth uniquely capable of generating life, or is life, in its most basic form, a common feature of the universe? The formation of water involves processes akin to supernovae; perhaps the genesis of life requires a similarly extraordinary scale of events, or even more? We need to find out.

I love that an entire scientific career could be founded from one interesting rock picked up on a field trip.

A little bit of a side here, but I'm impressed with the page's presentation. It's a university website, but the layout and overall design is really polished. Great work.

Does anyone know the smallest features preserved by fossils? For example, would cellular machinery like the ribosome be preserved? The shape of DNA? (Both assuming this cell had these)

frankly i don’t trust university reported news articles
