While humans did not come from mushrooms, there is evidence that mushrooms and humans share a common ancestor. Mushrooms are the fruits of a group of fungi called basidiomycetes and are more closely related to humans than plants. According to a study, the first mushrooms were present on Earth between 715 and 810 million years ago, much earlier than previously believed. This discovery suggests that mushrooms played a crucial role in the evolution of the first plants on the continental surface. While the specific evolutionary path from this ancient ancestor remains unclear, it is fascinating to consider the potential connections between humans and mushrooms, even if we did not directly evolve from them.

What You'll Learn
Humans and mushrooms share a common ancestor
While humans did not evolve from mushrooms, it is true that we share a common ancestor.
According to Mitchell Sogin, an evolutionary microbiologist, there was a single ancestral group of organisms, and some split off to become fungi, while others split off to become animals. This evolutionary tree is based on advanced automated DNA technology and computing power to trace the molecular evolution of dozens of today's oldest known species.
Fungi form a key part of the human microbiome, influencing our wellbeing. They are used in medicine and have been used in traditional spiritual practices for thousands of years. They are also used in day-to-day life, such as in the making of cheese, beer, wine, and bread.
Fungi are more closely related to humans than plants. In fact, mushrooms are the fruits of a group of fungi called basidiomycetes, and their cell walls are made of chitin, the same tough material found in the hard covering of insects. Fungi were also instrumental in allowing plants to move onto dry land over 400 million years ago, and fossils suggest that the first mushrooms were present on Earth between 715 and 810 million years ago.
While humans and mushrooms share a common ancestor, they are not members of the same branch. The evolutionary paths of fungi and animals diverged around 1.2 billion years ago.

Humans are more closely related to mushrooms than plants
Mushrooms, or fungi, are more closely related to humans than plants. While it may be tempting to think of mushrooms as plants, genetic comparisons have revealed that mushrooms are, in fact, closer to humans on the evolutionary tree.
Fungi form a key part of the human microbiome, the collection of microbes that live on and in our bodies. The human microbiome influences our wellbeing by interacting with other organisms within our bodies. This is one way in which fungi are closely related to humans.
Furthermore, genetic studies have shown that fungi and animals share a common ancestor, from which they evolved. In 1993, researchers Baldouf and Palmer published a paper titled 'Animals and fungi are each other's closest relatives: congruent evidence from multiple proteins'. They compared 25 proteins and their DNA sequences. This common ancestor likely exhibited sperm-like characteristics and later developed a stronger cell wall. Fungi and animals diverged from plants around 1.1 billion years ago.
Another reason why mushrooms are more closely related to humans than plants is that both mushrooms and humans store carbohydrate energy as glycogen, while plants use starch to store energy. Additionally, both mushrooms and humans produce vitamin D when exposed to sunlight.
While it is important to note that humans did not evolve from mushrooms, the evidence suggests that humans and mushrooms share a more recent common ancestor than either do with plants.

Mushrooms are the fruits of a group of fungi
While humans did not evolve from mushrooms, mushrooms (or fungi) and humans share a common ancestor. This ancestor is thought to have been a single-celled organism that lived between 715 and 810 million years ago, during the early stages of life on Earth.
Fungi form a key part of the human microbiome, influencing our wellbeing. They are also used in medicine, traditional spiritual practices, and the creation of antibiotics, as well as in the production of everyday essentials like cheese, beer, wine, and bread.
Fungi played a crucial role in allowing plants to move onto dry land over 400 million years ago, and this partnership between fungi and plants still exists today. Fungi have a unique feeding mechanism among eukaryotes, as they are the only ones capable of digesting food outside their bodies.
While humans did not evolve from mushrooms, our evolutionary history is closely linked, and fungi continue to play an important role in our daily lives and wellbeing.

Fungi form a key part of the human microbiome
While humans did not evolve from mushrooms, fungi form a key part of the human microbiome. The human microbiome is the collection of microbes that live on and in our bodies, influencing our wellbeing and how we interact with other organisms within our microbiomes.
Fungi are ubiquitous in our environment and are found on and in our bodies as constituents of the human microbiome, also known as the mycobiome. Every human has fungi as part of their microbiota, but the total number of fungal cells is significantly smaller than that of bacterial cells. The mycobiome has a significant impact on human health, especially when the host is compromised, and can be a cofactor in inflammatory diseases and metabolic disorders. Fungi in the human intestine, for example, elicit the induction of T helper 17 cells, which are central to protective immune responses.
The study of the fungal microbiome is a new and rapidly emerging field, and much remains unknown about oral fungal communities. However, it is known that the human oral microbiome includes pathogenic fungi, such as Candida, Aspergillus, Fusarium, and Cryptococcus. In the gut, yeast dominates the fungal microbiome, with Saccharomyces, Malassezia, and Candida being the most abundant genera. These three fungal species may be resident commensals in the human gastrointestinal tract and part of our core gut mycobiome.
Fungi have been used by humans for thousands of years as medicines and in traditional spiritual practices. More recently, fungal compounds have been used as antibiotics and in the development of treatments for ailments such as high cholesterol, mental health conditions, cancer, and Parkinson's disease. Fungi are also used in day-to-day life, including in the making of cheese, beer, wine, and bread, and as alternatives to meat, leather, and building materials.

Humans and mushrooms diverged from a common lineage 1.2 billion years ago
While humans did not evolve from mushrooms, the two do share a common lineage. Mushrooms, or fungi, are more closely related to humans than to plants. This is because fungi form a key part of the human microbiome, influencing our wellbeing and interacting with other organisms within our microbiomes.
Fungi have been used by humans for thousands of years as medicines and in spiritual practices, and they are also used in day-to-day life, such as in the production of cheese, beer, wine, and bread.
The evolution of fungi is a fascinating and complex process. Fungi are the only eukaryotes that can digest food outside their bodies. They were also crucial in allowing plants to move onto dry land over 400 million years ago, and fossils suggest that the first mushrooms may have appeared between 715 and 810 million years ago.
Humans and mushrooms diverged from a common lineage around 1.2 billion years ago. While we share a unique evolutionary history with fungi, we are not descended from them. Instead, we share a common ancestor with fungi, just as we do with apes and wolves.
The "Stoned Ape" hypothesis suggests that our ancestors ingested psilocybin mushrooms over millions of years, contributing to the development of our brains. However, this idea remains speculative and is not widely accepted.
