The Key to Life: Evolution of Fungi

Mar 26, 2024 | Nature, Videos

Fungi, a mysterious and fascinating life form, have been an important part of our planet for hundreds of millions of years. With their unique ability to break down organic matter and release essential elements like carbon, oxygen, nitrogen, and more into the soil and atmosphere, they have allowed for the development of complex ecosystems. Fungi are neither plant nor animal but instead belong to their own kingdom that separates them from both. They consume nutrients differently than animals or plants; animals eat their food which is then broken down by their bodies, while plants rely on photosynthesis to make their own food. On the other hand, fungi secrete enzymes through Mycelium (the root-like structure found on mushrooms) to digest nutrients externally.

Fungi’s immense size has also made them quite a spectacle. Currently alive on Earth is the largest single organism—a 3.5 square-mile fungus living underneath the Malheur National Forest in Oregon! Its mycelium has spread throughout the forest floor, connecting with trees and supporting the entire ecosystem there. And even more massive specimens have been found in fossils – some trunks reaching up to 20 or 30 feet tall! Fungi’s strength is also extraordinary —it can even break through Kevlar fabric!

It’s no wonder fungi have had such a huge impact on our planet’s development over time. They helped early ocean-based organisms transition onto land and allowed for life to regenerate after mass extinction events. They aided plants in settling onto land by providing support without roots available yet, and they’ve even been found inside tanks of nuclear waste matter in Chernobyl! Penicillin is fungal derived, as well as many other medicines that lower cholesterol and enable organ transplants; furthermore, they are essential components in many foods we regularly consume such as breads, cheeses, beer, etc… Finally, due to their ability to survive in space—they might even have played a role in creating our universe!

The future holds great potential for mushroom too: if it can ingest radiation and toxic chemicals here on earth—perhaps it can help us solve one of our biggest environmental problems: plastic pollution? When humanity travels out into space someday to explore different planets—fungi may be able to help terraform them so that they become inhabitable by human beings! If this all sounds too strange and mysterious for you—we recommend watching “Mushroom Magic”, an eye-opening documentary about these weird but wonderful organisms that will fully showcase their captivating capabilities!
