AI Insight
Earth's earliest evidence of life exists in ancient rock formations, predating forests, land animals, and dinosaurs. These traces were created by microscopic organisms that shaped the planet billions of years ago. However, these irreplaceable geological records are now threatened with loss or destruction.
Why it matters
Understanding Earth's earliest life forms provides crucial insights into how life originated and evolved on our planet. The potential loss of these ancient fossils would eliminate key evidence needed to study the origins of life and could impact our ability to recognize similar biosignatures on other planets.
Understand the Science
Today, our planet is teeming with life, but it has not always looked the same. Long before forests reached skyward, animals walked on land and dinosaurs rose and fell, our planet was shaped by a much smaller, more unassuming form of life. And we can still find traces of it today.
