Mushrooms are a member of the fungi group of eukaryotic organisms, which also includes mould and yeast. Fungi are one of the oldest and largest groups of living organisms, with evidence suggesting that they first appeared around one billion years ago. The fossil record of fungi is sparse, but fossils of filamentous fungi have been dated to between 715 and 810 million years ago, and fossils containing fungal filaments have been dated to around 2.4 billion years old. The earliest terrestrial fungus fossils have been found in South China and date back around 635 million years. The first mushrooms are thought to have evolved between 715 and 810 million years ago, and fossils found in the Democratic Republic of Congo indicate that microscopic mushrooms may have been important partners of the first plants that colonized the Earth's surface around 500 million years ago.

Fossil evidence suggests mushrooms are 715-810 million years old
Fossil evidence suggests mushrooms are 715–810 million years old. This discovery was made by a team led by Steeve Bonneville from the Université libre de Bruxelles. The fossils were found in the Democratic Republic of Congo and formed in a lagoon or coastal lake environment.
The fossils were identified as fungal remains through the use of cross-correlated chemical and micro-spectroscopic analyses. Specifically, Bonneville used three techniques to show that the filaments, which extend like a woven mesh, contain a material called chitin on their exterior, a clear sign of a fungus. Few organisms create chitin, and those that do don't form these kinds of filaments. One detection technique employs a fluorescent dye to bind to the chitin.
This discovery has major implications for our understanding of the evolution of organisms on Earth. Previously, the oldest fossil fungi were thought to date back to the middle Paleozoic, about 460 million years old. This discovery pushes back the origins of fungi by 300 million years and changes our understanding of the evolution of plants and animals on Earth.
Fungi are a major contributor to life on Earth and play a crucial role in breaking down detritus and dead things, cycling nutrients throughout the environment, and making plant life possible. They also have important roles in fermentation, creating alcohol, leavened bread, and more. However, much of the distant history of fungi remains a mystery due to the limited fossil record. Fungi do not biomineralise, so they do not readily enter the fossil record, and their soft, fleshy fruiting bodies do not preserve well over time.

The earliest mushroom fossils were found in the Democratic Republic of Congo
The age of mushrooms has been a topic of intrigue for evolutionary experts for centuries. The earliest mushroom fossils were found in the Democratic Republic of Congo, preserved in rock near the city of Mbuji-Mayi. The fossils were discovered to be between 715 and 810 million years old, with some estimates placing them at 800 million years old. This discovery was made by a team of scientists led by Steeve Bonneville from the Université libre de Bruxelles, Belgium. The fossils were found in ancient rocks that formed in a lagoon or coastal lake environment, dating back to when life on Earth's surface was in its infancy.
The identification of these fossils was a significant challenge due to the delicate nature of mushroom remains and their resemblance to other microorganisms. Previous attempts relied solely on the morphology of organic remnants extracted from rocks with corrosive acids, which often led to incorrect interpretations. Bonneville and his team employed multiple molecular analysis techniques, including confocal laser scanning fluorescence microscopy and chemical and micro-spectroscopic analyses, to accurately identify the fossilised remains of microscopic mushroom parts called mycelium.
The discovery of these ancient mushroom fossils has important implications for our understanding of early life on Earth. According to Bonneville, the presence of fungi in the transitional area between water and land suggests that mushrooms played a crucial role in the evolution of plants and fungi on the Earth's surface. This finding also sheds light on the evolution of other organisms, prompting scientists to reconsider the timeline of evolution.
Furthermore, the discovery of ancient mushroom fossils contributes to our understanding of the Kingdom Fungi, which is estimated to have 2.2 to 3.8 million species, with only about 120,000 documented so far. Fungi are essential for breaking down detritus and dead matter, and they cycle nutrients throughout the environment, playing an often unseen yet vital role in the functioning of the world. By studying these ancient fossils, scientists can gain insights into the evolution of fungi and their impact on the planet's ecosystems.

The first mushrooms may have been partners to the first plants
The evolution of fungi has been a topic of interest for scientists for years. While the fossil record of fungi is meagre, scientists have discovered fossils that resemble modern-day mushrooms. According to a study led by Steeve Bonneville from the Université libre de Bruxelles, the first mushrooms evolved on Earth between 715 and 810 million years ago, 300 million years earlier than previously thought. This discovery was made by cross-correlating chemical and micro-spectroscopic analyses of structures found in ancient rocks.
These ancient rocks, found in the Democratic Republic of the Congo, formed in a lagoon or coastal lake environment. The presence of fungi in this transitional area between water and land suggests that mushrooms were important partners of the first plants that colonized the Earth's surface. Fungi are known to form symbiotic relationships with plants, connecting them through an underground fungal highway called the "wood-wide web," which facilitates the transport of nutrients and signals.
Additionally, the discovery of 1 billion-year-old fungi in Canada further supports the idea that fungi played a crucial role in the evolution of life on Earth. Fungi were some of the first complex life forms on land, breaking down rocks for nourishment and contributing to the formation of soil. They also played a role in oxygenating the Earth's atmosphere after the Cryogenian glaciations.
Fungi have had a significant impact on the development of life on Earth, including plants and animals. They have been integral to processes such as brewing beer, making contaminated water safe to drink, and even enhancing the immune system, as evidenced by the medicinal use of mushrooms by ancient humans.

Ancient mushrooms may have helped oxygenate the Earth's atmosphere
The evolution of fungi dates back to at least 1.2 to 1.5 billion years ago, with some fossils suggesting origins of over 2 billion years. The earliest terrestrial fungus fossils have been discovered in South China and date back to around 635 million years ago. These ancient fungi may have played a crucial role in oxygenating the Earth's atmosphere following the Cryogenian glaciations.
While the specific timeline for the emergence of mushrooms is less clear, studies indicate that they evolved significantly earlier than previously thought. Research led by Steeve Bonneville suggests that mushrooms first appeared between 715 and 810 million years ago, 300 million years earlier than previously estimated. This discovery was based on the identification of fungal remains in ancient rocks from the Democratic Republic of the Congo. The presence of these microscopic mushrooms indicates their potential partnership with the first plants that colonized the Earth's surface.
The role of ancient mushrooms in oxygenating the Earth's atmosphere is supported by their ecological significance. Fungi, including mushrooms, are a major contributor to life on Earth. Today, the Kingdom Fungi is estimated to encompass 2.2 to 3.8 million species, highlighting their diversity and abundance. As fungi, mushrooms contribute to the Earth's biomass and play essential ecological roles, such as decomposition and nutrient cycling.
Additionally, mushrooms have a long history of use by humans, dating back thousands of years. Magic mushrooms, in particular, have been utilized for ritual, religious, medicinal, and recreational purposes. Ancient civilizations, such as those in Central America and Egypt, incorporated mushrooms into their cultural and spiritual practices. The discovery of ancient artwork, manuscripts, and constructs provides evidence of the importance of mushrooms in these societies. Furthermore, the use of mushrooms by prehistoric cultures may extend even further back in time, as suggested by stone paintings from North Africa and Spain.
In conclusion, ancient mushrooms may have played a significant role in oxygenating the Earth's atmosphere, particularly during the recovery from the Cryogenian glaciations. The evolutionary history of fungi and mushrooms reveals their ancient origins and ecological importance. Moreover, the long-standing relationship between humans and mushrooms, dating back to the birth of civilization, underscores the impact they have had on human culture and consciousness.

Mushrooms are a monophyletic group, meaning they can be traced to a single ancestor
The age of mushrooms and their evolutionary history have been subjects of extensive research. According to recent studies, the first mushrooms evolved on Earth between 715 and 810 million years ago, much earlier than previously thought. This discovery has prompted scientists to reconsider the timeline of life on Earth, as it suggests that mushrooms played a significant role in the early colonization of the planet's surface by plants.
The presence of ancient mushrooms was identified in rocks from the Democratic Republic of Congo, which formed in a transitional area between water and land. This led researchers to believe that mushrooms were important partners to the first plants that inhabited the Earth's surface. Additionally, the discovery of one billion-year-old fungi in Canada further emphasizes the ancient origins of fungi, including mushrooms.
Mushrooms, as part of the Kingdom Fungi, are classified as a monophyletic group. This means that all modern fungi, including mushrooms, can be traced back to a single common ancestor. Phylogenetic relationships, which study the ancestral connections between organisms, have revealed that animals and fungi share a closer relationship than previously thought, forming a monophyletic group distinct from plants and protists.
Evidence from DNA analysis suggests that the most recent common ancestor of all fungi lived approximately 1.2 to 1.5 billion years ago. Some basalt formations in South Africa, dating back 2.4 billion years, contain structures resembling filamentous fossils, indicating that the origins of fungi may extend even further back in time. The fossil record of early fungi is sparse due to their soft, fleshy nature, which makes preservation challenging. However, the discovery of ancient fungal remains provides valuable insights into the evolution of life on Earth.
