Mushrooms are a fascinating type of fungi with unique characteristics. They are not aliens, but the product of evolutionary processes that took place on Earth. While they may seem otherworldly, mushrooms are believed to have first evolved on Earth between 715 and 810 million years ago, according to a study by Steeve Bonneville from the Université libre de Bruxelles. This discovery pushes back the previously believed timeline by 300 million years. The study identified fossilized remains of mycelium, a network of interconnected microscopic strands, in ancient rocks from the Democratic Republic of the Congo. This suggests that mushrooms played a significant role in the colonization of the Earth's surface by plants. With their complex traits, symbiotic relationships, and potential for medicinal and culinary uses, mushrooms are an intriguing and essential part of Earth's biodiversity.

Mushrooms are the product of evolutionary processes on Earth
The first mushrooms on Earth are estimated to have evolved between 715 and 810 million years ago, according to a study led by Steeve Bonneville from the Université libre de Bruxelles. This discovery was made by analysing the fossilized remains of mycelium, a network of interconnected microscopic strands, found in rocks from the Democratic Republic of the Congo. The presence of these ancient fungal remains suggests that mushrooms played an important role in the early colonization of plants on Earth's surface.
Furthermore, mushrooms possess unique traits that set them apart from other life forms. They have symbiotic and parasitic relationships with plants, animals, and other fungi. The study of mushrooms, known as mycology, reveals that the round, colourful structure we typically associate with mushrooms is merely the \"fruit\" of a much larger underground organism, the mycelium.
Additionally, mushrooms have been found to have a mutually beneficial relationship with plants. Plants provide fungi with carbon-rich sugars, while fungi supply plants with nutrients from the soil. This exchange is facilitated by mycelial networks, which also enable communication between different plants in a forest ecosystem.
While mushrooms are indeed earthly products of evolution, they continue to fascinate and surprise us with their unique characteristics and contributions to the natural world.

The first mushrooms evolved on Earth 715-810 million years ago
Mushrooms, classified as fungi, are the product of complex evolutionary processes that took place on Earth. 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 believed. The fossilized remains of mycelium, a network of interconnected microscopic strands, were discovered in rocks from the Democratic Republic of Congo that were approximately 715 to 810 million years old.
The presence of these ancient fungi in a transitional area between water and land suggests that they played a crucial role in the colonization of the Earth's surface by plants around 500 million years ago. Bonneville and his team used chemical and micro-spectroscopic analyses to identify the fungal remains in the rock, marking a significant discovery that reshapes our understanding of the evolution of organisms on our planet.
The study of mushrooms, known as mycology, reveals unique traits that set them apart from other life forms. For instance, they build cell walls out of chitin, the same material found in the hard outer shells of insects and arthropods. Their spores are electron-dense and can survive in the vacuum of space, with an outer layer that naturally deflects ultraviolet light.
While mushrooms are undoubtedly of Earthly origin, their ability to thrive in extreme conditions and their presence in every level of Earth's atmosphere spark intriguing discussions about their potential extraterrestrial connections. However, there is still no firm evidence of life beyond Earth, and the evolution of mushrooms remains a fascinating yet mysterious aspect of our planet's history.

Mushrooms are part of the fungi kingdom
Mushrooms are indeed from Earth and are part of the fungi kingdom. The study of mushrooms is called mycology, which differs from the disciplines of biology and botany. Fungi are some of the most widely distributed organisms on Earth and are of great environmental and medical importance. The English word "fungus" is directly adopted from the Latin "fungus" (mushroom), used in the writings of Horace and Pliny. This, in turn, is derived from the Greek word "sphongos" ("sponge"), which refers to the macroscopic structures and morphology of mushrooms and molds. The root is also used in other languages, such as the German "Schwamm" ("sponge") and "Schimmel" ("mold").
The 2007 classification of Kingdom Fungi is the result of a large-scale collaborative research effort involving dozens of mycologists and other scientists working on fungal taxonomy. It recognizes seven phyla, two of which—the Ascomycota and the Basidiomycota—are contained within a branch representing subkingdom Dikarya, which includes all the mushrooms, most food-spoilage molds, most plant pathogenic fungi, and the beer, wine, and bread yeasts. The kingdom Fungi encompasses an enormous diversity of taxa with varied ecologies, life cycle strategies, and morphologies ranging from unicellular aquatic chytrids to large mushrooms.
The first mushrooms evolved on Earth between 715 and 810 million years ago, 300 million years earlier than previously thought. Fossilized remains of mycelium (a network of interconnected microscopic strands) were discovered in rocks from this time period, indicating that fungi were important partners of the first plants that colonized the Earth's surface. Fungi have a symbiotic relationship with plants, animals, and other fungi, as well as a parasitic one. They often grow in soil and, in the case of mushrooms, form conspicuous fruit bodies that sometimes resemble plants such as mosses.
Fungi build cell walls out of chitin, the same material that makes up the hard outer shells of insects and other arthropods. These cell walls contain similar chemicals found in butterfly and beetle wings, as well as the plumage of some colorful birds, such as peacocks. Fungi form and release vast quantities of spores as part of their life cycle, and these spores are the main reproductive units for fungi. Mushroom spores are electron-dense and can survive in the vacuum of space.

Fungi have a symbiotic relationship with plants, animals and other fungi
Mushrooms, classified as fungi, are indeed from Earth. They are the product of complex evolutionary processes that took place on our planet. The first mushrooms are believed to have 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 organism evolution on our planet.
Fungi, including mushrooms, often have symbiotic relationships with plants, animals, and other fungi. These relationships can be mutualistic, where both organisms benefit, or parasitic, where the fungus benefits at the expense of the host organism. In a mutualistic relationship between a fungus and a plant, the fungus grows in or on the plant roots, benefiting from easy access to food made by the plant. In return, the plant benefits from the fungus's mycelia, which help absorb water and nutrients from the soil. This relationship is called mycorrhiza and is believed to have allowed plants to first colonize the land. Nearly 90% of all vascular plant species have mycorrhizal partners.
Fungi also form mutualistic relationships with photosynthetic organisms, typically cyanobacteria or green algae. The fungus grows around the bacterial or algal cells, benefiting from a constant supply of food produced by the photosynthesizer. In turn, the photosynthesizer benefits from the water and nutrients absorbed by the fungus. This organism resulting from the mutualistic relationship between a fungus and a photosynthetic organism is called lichen. Lichens can survive in extreme environments, such as rocks, gravestones, tree bark, and tundra, where plant roots cannot penetrate. They can withstand extended droughts and rapidly become active again when water is available.
Additionally, fungi can have parasitic relationships with plants and animals, including insects and humans. Parasitic fungi penetrate the host and break down its tissues to obtain nutrients. They can cause illness and may eventually kill their host. For example, the white parasitic fungus Cordyceps grows on a moth.

Fungi may have been important partners for the first plants on Earth
Mushrooms are indeed from Earth. They are the product of complex evolutionary processes that took place on our planet. 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, much earlier than previously thought. This discovery was made by examining the fossilized remains of mycelium, a network of interconnected microscopic strands, found in ancient rocks from the Democratic Republic of the Congo.
Fungi, including mushrooms, may have played a significant role in the early history of life on Earth. The study by Bonneville and colleagues suggests that mushrooms could have been important partners for the first plants that colonized the Earth's surface. This hypothesis is based on the presence of fungi in transitional areas between water and land, indicating a potential symbiotic relationship with early plant life.
The unique characteristics of fungi, such as their ability to build cell walls out of chitin and produce spores that can survive in extreme conditions, may have been advantageous to early plants. Fungi also played a crucial role in the evolution of land animals by influencing the Earth's climate. The presence of lichen fungi and plants is believed to have contributed to the lowering of the Earth's surface temperature during the Snowball Earth events and the increase in atmospheric oxygen levels.
Furthermore, fungi and plants may have worked together to reduce atmospheric carbon dioxide levels. After a plant dies, some of its carbon can become locked up in the lignins and eventually buried in the Earth through geologic processes, preventing those carbon atoms from returning to the atmosphere. This reduction in carbon dioxide, a powerful greenhouse gas, could have had a significant cooling effect on the Earth's atmosphere, creating the conditions necessary for the evolution and diversification of land animals.
While the specific mechanisms and extent of the partnership between early fungi and plants are still being studied, it is clear that fungi played an important role in the early history of life on Earth and continue to be essential components of terrestrial ecosystems today.
