The story so far
The rock, known as chert, contains what researchers describe as one of Earth's earliest known occurrences of biologically generated organic matter. This finding is significant because it pushes back the potential timeline for the emergence of life on Earth by hundreds of millions of years.
However, the evidence is not conclusive. The rock also contains fossils dating to 1.7 billion years ago, which complicates the timeline of complex life's beginnings.
The Debrief, telegraphindia.com, The Economic Times, Science Daily and Phys.org have all covered the story. The next steps involve further analysis of the rock's composition and context to better understand the potential microbial life it may contain.

The obvious questions
What is the significance of the 3.5-billion-year-old rock found in India?
The rock contains organic matter that researchers believe may be evidence of one of Earth's earliest known occurrences of biologically generated organic matter. This pushes back the potential timeline for the emergence of life on Earth by hundreds of millions of years.
Where was the rock discovered?
The rock was discovered 20 kilometers south of Jamshedpur, India.
What complicates the timeline of complex life's beginnings?
The rock also contains fossils dating to 1.7 billion years ago, which complicates the understanding of when complex life began on Earth.
