Fungi, including mushrooms, are often thought of as plants because they are found in similar environments and sometimes look like plants. However, in reality, fungi are more closely related to humans than they are to plants. This fact might sound surprising to many, as we typically associate mushrooms with the plant kingdom. However, scientific studies have revealed that fungi share some critical biological and genetic characteristics with animals, which sets them apart from plants in more ways than one.
In this article, we’ll explore the surprising genetic and biological connections between fungi and humans, how fungi differ from plants, and the fascinating scientific reasons behind these similarities. Additionally, we will address some common myths and misconceptions about fungi’s relationship to both humans and plants.
Do Mushrooms Share DNA With Humans?
To understand why fungi are more closely related to humans than plants, we first need to dive into DNA. DNA is the blueprint of life, carrying the genetic information that determines an organism’s traits and functions. By comparing the genetic code of different organisms, scientists can determine how closely related they are.
Research has shown that fungi, particularly mushrooms, share significant portions of their DNA with animals, including humans. While this is true, it does not mean that mushrooms are genetically identical to humans, but rather that certain elements of our DNA are more similar to fungi than to plants. For example, fungi and animals both have chitin in their cell walls, whereas plants have cellulose. This molecular similarity plays a critical role in explaining the biological connection between humans and fungi.
One of the most notable similarities between humans and fungi is the way both groups process and metabolize food. Fungi, like humans, are heterotrophic organisms, meaning they rely on external sources of organic material for nutrition, rather than using photosynthesis like plants. This is a crucial distinction that further reinforces the idea that fungi have more in common with animals than with plants.
Fact Check: Mushrooms Share More DNA With Humans Than Plants
When it comes to DNA, mushrooms share more in common with humans than with plants. The genetic makeup of fungi is closer to that of animals, including humans, than to the plant kingdom. This finding has been confirmed through multiple studies examining the genomic similarities between different life forms.
A 2018 study published in *Nature Microbiology* revealed that the genes responsible for the structure and function of fungal cells are remarkably similar to those found in animals, including humans. For instance, both humans and fungi have genes that control complex metabolic processes and immune responses. On the other hand, plants have significantly different genetic markers and structures.
Furthermore, the fact that fungi can form complex networks and interact with their environment in ways similar to animals—through the movement of materials, exchange of information, and adaptation to changing conditions—further supports the idea that fungi are more like animals than plants.
Three Reasons Fungi Are Not Plants
There are three primary reasons fungi are distinct from plants, despite their outward appearance sometimes resembling vegetation. These reasons also help explain why fungi are more similar to humans than plants.
1. Lack of Photosynthesis: Unlike plants, which use photosynthesis to produce their food from sunlight, fungi are unable to generate their energy in this way. Instead, they absorb nutrients from organic matter, much like animals. Fungi secrete enzymes that break down complex substances in their environment, which they then absorb through their cell walls. This difference in energy acquisition places fungi in a category that aligns them more with animals than with plants.
2. Cell Wall Composition: Plants have cell walls made of cellulose, a tough carbohydrate that helps them maintain their structure. Fungi, on the other hand, have cell walls made of chitin, a substance also found in the exoskeletons of arthropods (such as insects and crustaceans). This key distinction underscores the genetic and structural differences between fungi and plants.
3. Growth and Reproduction: While plants typically reproduce through seeds or spores, fungi reproduce through the release of spores. Additionally, fungi grow in a network of filaments called hyphae, which is fundamentally different from how plants develop from roots, stems, and leaves. This unique mode of growth further sets fungi apart from plants.
