Fungi Colonized Earth a Billion Years Before Plants, Study Finds
New research reveals fungi were the first ecosystem engineers, shaping Earth's continents and creating soil nearly a billion years before the first plants emerged.
Fungi's Ancient Reign Redefined
New research has overturned the timeline of life on land, revealing that fungi colonized continents between 0.9 and 1.4 billion years ago. This finding predates the arrival of the first land plants by hundreds of millions of years.
The study, published in Nature Ecology & Evolution, repositions fungi from background organisms to the planet's first ecosystem engineers. They were not just present; they were actively shaping a barren planet, making it habitable for future life.
A New Timeline for Life
An international team of researchers, including scientists from the Okinawa Institute of Science and Technology (OIST) and the University of Bristol, established this new timeline. They moved beyond relying solely on the sparse fungal fossil record.
Methodology: Scientists integrated data from rare horizontal gene transfers with fossil calibration points.
Previous Estimate: Plants were believed to be the first terrestrial pioneers, emerging around 470 million years ago.
New Understanding: Fungi had a nearly billion-year head start, fundamentally altering terrestrial environments long before plants took root.

Architects of a Habitable Planet
Long before complex life, fungi were performing critical functions that transformed Earth’s sterile, rocky continents. They were the primary architects of the planet’s early biosphere.
Creating the First Soils
These ancient organisms were masters of decomposition and nutrient cycling. By breaking down bare rock, they kickstarted the process of soil formation, a prerequisite for the eventual colonization by plants.
Pioneering Partnerships
The research suggests that early fungi formed symbiotic relationships with algae, similar to modern lichens. This partnership was crucial for survival on a barren planet.
Fungi provided algae with shelter and minerals extracted from rock.
Algae, in turn, provided fungi with energy through photosynthesis.
Together, this collaboration accelerated rock weathering and the creation of primitive soils, laying the literal groundwork for all subsequent terrestrial life.

Reassessing Earth's History
This discovery has profound implications for our understanding of major evolutionary and climatic events in Earth's history.
Challenging the Plant-Centric View
The research compels a major reevaluation of early life, shifting the focus from a plant-centric model to one where fungi were the foundational pioneers. Plants did not colonize empty continents; they arrived on a world already engineered by fungi.
Influence on Global Climate
The large-scale activity of fungi likely had a significant impact on the planet's climate. By breaking down rocks and interacting with early algae or cyanobacteria, they could have influenced atmospheric carbon and oxygen levels. Researchers believe this may have had a role in major global events:
"Snowball Earth" Glaciations: Fungal activity could have drawn down atmospheric CO₂, potentially triggering global cooling.
Cambrian Explosion: The subsequent rise in oxygen may have helped fuel the rapid diversification of animal life.
This study confirms that the story of life on land is far older and more complex than previously known, with fungi playing the leading role for nearly a billion years.
