Mushrooms and humans share a surprising amount of DNA. While it may be surprising to some, mushrooms are more closely related to humans than to plants. In fact, humans share nearly 50% of their DNA with fungi. This is because animals and fungi share a common ancestor, branching away from plants around 1.1 billion years ago. Mushrooms and humans share certain genetic characteristics that plants do not have, and only a few tiny changes in DNA structure separate the two.

What You'll Learn
Humans and mushrooms share nearly 50% of their DNA
It may come as a surprise, but humans and mushrooms share nearly 50% of their DNA. This means that, genetically speaking, mushrooms are more closely related to humans than to plants. While mushrooms may not appear biologically similar to humans, our shared genetic traits with mushrooms outnumber those with plants.
This phenomenon can be explained by the evolutionary history of mushrooms and humans. Studies have found that humans share about a quarter of their active genes with mushrooms. This is because mushrooms and humans evolved from ancestors engaged in multicellularity over a billion years ago. As mushrooms evolved on their own path, they retained genetic DNA remnants from our shared origins. On a molecular level, humans and mushrooms share a close kinship.
The genetic similarity between humans and mushrooms has implications for both culinary and medicinal practices. The meaty taste of mushrooms is likely due to glutamate, a neurotransmitter found in savory foods, including meats. This similarity in taste may be influenced by the genetic relationship between mushrooms and animals, although further research is needed to confirm this connection.
Additionally, mushrooms possess unique medicinal properties that can boost immunity, fight tumors, lower inflammation, and support brain health. Research on psilocybin and other hallucinogenic mushroom compounds has shown promise in treating mental health issues and facilitating psychological growth. The ability of mushrooms to connect with disparate life forms through cooperative networks has been recognized by ancient cultures, who revered mushrooms for their psychedelic compounds and their ability to induce dream-like states.
In summary, the fact that humans and mushrooms share nearly 50% of their DNA highlights the unexpected closeness of their evolutionary relationship. This genetic similarity has led to intriguing connections in terms of taste, medicine, and even spiritual exploration. As research continues to uncover more about the genetic diversity within the fungal kingdom, we may discover further surprising similarities between humans and mushrooms.

Fungi and animals share characteristics that plants do not
Mushrooms, and fungi more broadly, share a closer genetic relationship with humans than with plants. Mycologists Paul Stamets and Matt Kasson have asserted that humans and mushrooms share nearly 50% of their DNA. This is due to the existence of major overlapping characteristics between fungi and animals that are not present in plants.
One such characteristic is the presence of chitin, which is found in fungi and animals but not in plants. Chitin forms the cell walls of fungi and the shells of bugs, but plants instead have cell walls made of cellulose. Fungi are also consumers rather than producers, as they lack the ability to generate chemical energy from sunlight via chloroplasts.
The grouping of fungi with plants is a historical convention that has persisted into the present. Early taxonomists observed that fungi were immobile and had rigid cell walls, and thus classified them as distinct from animals but similar to plants. However, modern taxonomic classifications have benefited from the development of molecular tools, which have revealed that fungi are more closely related to animals than to plants.
The evolutionary relationship between fungi and animals can be traced back to a common ancestor between 1.1 and 1.5 billion years ago, while the common ancestor shared by fungi and plants is estimated to have lived around 1.6 billion years ago. This suggests that fungi and animals share characteristics that are not present in plants due to their more recent shared ancestry.

Mushrooms branched away from plants around 1.1 billion years ago
Mushrooms, or fungi, are more closely related to humans than to plants. This is because fungi branched away from plants around 1.1 billion years ago, and only later did animals and fungi separate on the genealogical tree of life.
Fungi belong to their own kingdom, just like animals, plants, bacteria, and protists (algae). They are eukaryotic organisms that absorb nutrients from other organic matter. Fungi typically begin the decomposition process when a tree falls or an animal dies.
The first hypotheses about the relationship between fungi and animals emerged in the 1950s. Fungi and animals share a common ancestor, which was likely a single-celled organism with sperm-like characteristics. Fungi probably colonized the land during the Cambrian, over 500 million years ago, and possibly 635 million years ago during the Ediacaran. However, terrestrial fossils only become uncontroversial and common during the Devonian, 400 million years ago.
Evidence from DNA analysis suggests that all fungi are descended from a most recent common ancestor that lived at least 1.2 to 1.5 billion years ago. It is probable that these earliest fungi lived in water and had flagella. Humans share nearly 50% of their DNA with fungi, according to Paul Stamets, a mycologist and author. This is why mushrooms sometimes have a meaty taste and texture.

Fungi and humans share a common ancestor
Mushrooms and humans share about 50% of their DNA, according to Paul Stamets, a mycologist and author. This is because fungi and humans share a common ancestor, which was probably an organism like an amoeba or a slime mould. Fungi and animals, including humans, branched away from plants around 1.1 billion years ago.
Fungi are more closely related to animals than to plants. They share genetic characteristics that plants do not have. Animals and fungi share similarities in certain proteins that plants and bacteria do not have. This suggests that animals and fungi are sister groups, while plants constitute an independent evolutionary lineage.
The first hypotheses about the relationship between fungi and animals emerged in the 1950s. Scientists were later able to test and confirm these suspicions. The genomic features that are characteristic of animals and fungi arose even before the origin of these two kingdoms. Fungi and animals share reserve materials, which are, firstly, fat, and secondly, glycogen, a polysaccharide that is stored in the liver in animals, and in fimbriae in fungi.
Fungi and animals also share the ability to communicate, move, have sex, and fight. Fungi communicate through chemical signals, sending and receiving them to find sexual partners. Fungi can move, especially those belonging to old evolutionary lines. Some produce cell walls only at certain stages of their life, and at other stages, they maintain the amoeba stage, which means they can move independently by stretching out their pseudopodia.
Fungi have their own kingdom, just like animals, plants, bacteria, and protista (algae). They are eukaryotic organisms that absorb nutrients from other organic matter.

Humans and mushrooms have similar motility
Mushrooms and humans share a surprising amount of DNA. While it is not as simple as stating that they share 50% of their DNA, it is true that mushrooms are more closely related to humans than to plants. This is due to the fact that fungi and animals share a common ancestor, which was likely a single-celled organism with sperm-like characteristics.
The similarities between fungi and animals are not merely historical, but are also reflected in their genetic makeup. Fungi and animals share certain genetic similarities not found in plants, such as the hox gene, which controls multicellularity. The proteins and DNA sequences of fungi and animals also exhibit similarities not found in plants or bacteria.
The motility of certain fungi is an example of a characteristic shared by both fungi and animals. Some fungi can move or seem to crawl, and this is achieved through flagella, a tail that whips in a similar way to a sperm cell. This is a characteristic that no plant possesses, but humans do.
The shared ancestry of fungi and animals has also led to similarities in their taste and texture. Mushrooms often taste and feel more like meat than plants, and this may be due to their genetic relationship with animals. While there is a huge range of flavors among different mushroom species, many have a distinctly meaty taste.
In conclusion, humans and mushrooms do share similar motility, and this is just one of several surprising similarities between the two. While DNA is a complex molecule that cannot be reduced to a simple percentage of similarity, it is clear that mushrooms and humans are closely related in evolutionary terms, and this is reflected in various ways.
