Charles Darwin & His Worms
Originally a geology student, Charles Darwin ended up spending a lot of time studying earthworms. In his day, worms were seen as nothing but pests, but he was fascinated. Through a series of experiments, that
lasted over three decades, he discovered worms literally move the earth.
It’s estimated that, over the course of a year, on only one acre, earthworms move eight tons of earth. That would be a full load for the average dump truck, give or take.
But they don’t just move, aerate and overturn the soil, they make make more of it. About two inches worth a year. They leave their nitrogen, phosphorous and calcium rich castings (poop) up on the surface, causing the previous surface to slowly submerge. They keep doing it, and it keeps mixing down, in a constant ever-moving renewal.
Earthworms are incredibly ancient. They first appeared half a BILLION – with a B – years ago. They were part of the “Cambrian Explosion,” a brief period when all the major animal groups first appeared. Of course, having no bones, worms don’t leave a lot of fossils. But in rare instances of unusual preservation, they have been found. Most of the worms from that time, naturally, are extinct. But, amazingly, there is one still alive today.
This means worms, and their long line of ancestors, really are the original movers and shakers!
But that’s just the beginning.
Flimsy, boneless little worms are surprisingly strong. They have to be. In order to be able to move through the dirt, they need to forcefully enlarge tiny gaps and crevices. This is a lot of weight to push against. But full grown worms can push ten times their own weight. Baby earthworms are even stronger. They can push five hundred times their own weight.
Being totally voracious, they eat…and poop…their own weight, everyday. That doesn’t sound like much, seeing as they aren’t that big. But in that same one acre of land, assuming it has relatively healthy soil,
there can be more than a million earthworms.
With that much strength and that much eating and pooping, in those kinds of numbers, it’s no wonder they are such incredible earth-movers. It just goes to show how the power of small actions done over and over can change the world.
Worms don’t have eyes, but can sense light. They need to move away from it. Because if exposed to light for more than an hour or so they will become paralyzed. And, if their skin dries out, they will die.
They sense sound vibrations, too, without having ears. Darwin discovered this by putting them in a pot of soil on his piano. There is a strong evolutionary imperative to avoid the vibrations of underground
predators, like moles.
They also have intelligence without much of a brain. Darwin suspected as much. He did an experiment with paper triangles expecting the worms to pull them from the points, which would be the easiest, into their burrows, and that’s just what they did.
More recently, scientists put a worm brain into a lego robot. And it worked. Actually, they simulated the
connections between C. elegans’ 302 neurons into software that was uploaded into a toy robot. And without any other extra programming, the lego robot behaved in ways similar to the worm. 302 neurons is not a lot. They can’t use them to solve algebraic equations, but so what?
Actually, most worms can be said to have two brains. They have two cerebral ganglia, which are connected all throughout their bodies—organs, skin & muscles. You could say their two brains are their body. Or, their body is their double brain. Or…they are all brain. A long, skinny bundle of sense perception eating their way through the Divine Substance!
But I wax poetic…
Motor and sensory signals run through nerve bundles throughout the body. These, obviously, enable responses to the environment and maintain bodily functions like circulation, digestion, respiration, heart rate, temperature regulation, pain response, etc. Same as for everybody.
Their nervous system is also attached to sensitive chemo-receptors on their skin. With these they are either attracted to or repulsed by substances they encounter. This tells them to move toward or away,
as need be.
So, no. They’re not rocket scientists. But, unlike rocket scientists, they’re actually necessary to the formation and continued existence of Life on this planet. Upon reflection, it seems that instead of saying worms have intelligence, it’s probably more accurate to say they are intelligence. One of many extensions of the Intelligence we know as Life. There’s a lot more to them than you might expect and they deserve our respect.
What Can We Learn from Worms?
A lot, as it turns out. Human cultures across the world find great symbolic meaning in the lowly worm. Humility, for one thing. When we can get over our human arrogance, we become better versions of ourselves. Staying grounded and keeping our connection with reality. No holy wars or delusions of grandeur with these critters!
Worms also demonstrate the enormous, tactile power of intuition. Intuition is not some weak willed, wishy washy thing to disregard. It is powerful. Look at them! They have no eyes, ears, arms or legs. All they have is their inner knowing and persistence. All they do is trust and follow their sense perceptions. And they, literally, move the earth. We would do well to incorporate more of that into our frenzied, stress-filled lives.
Compulsive over thinking is bad for our sanity, both individually and collectively.
In many cultures worms are seen as symbols of spiritual enlightenment. Their place in the life cycle, turning dead matter into living soil and, by extension, new life is not a made up fairy tale. It’s Real. We’d probably be a lot healthier and happier by grounding our beliefs about the life, death & rebirth cycles in something tangible, alive today, and available to observe everywhere.
Worms Are Great!
Charles Darwin was right to be fascinated by worms. As both a geologist and a deeply religious person, he must have unconsciously (or consciously) seen them, somehow, as the embodiment of the Divine
Mind, alive and moving through the dirt. Or something along those lines. And I have to wonder. Are worms what caused him to abandon geology and pursue, instead, his study of the Origins of Life? If
so, the humble earthworm has certainly moved a lot more than dirt.
(I’m not saying that’s what happened. I’m just wondering…)
PS I love worms so much, I even write poetry about them!

This is a fantastic article on worms! I learned so much from reading this blog post. I remember when I was in elementary school, I had a teacher that had a composting mechanism where there were a bunch of earthworms placed in a tank along with soil and other organic material. It was super interesting learning how it worked and how earthworms improve the environment.
Hi Kevin. Thanks!
I really enjoyed writing it…and it got so long, because there is so much about them, that I had to split it into two!
I remember being forced to dissect them in high school. And it still gives me the shivers. I came across a quote that said, to understand worms is to understand life. And I believe it.

Great post! It’s always fascinating to learn more about the tiny creatures that play such a crucial role in our ecosystems. Worms truly are the unsung heroes of the soil, and it’s amazing to think about all the ways they contribute to our gardens and farms. This post does a fantastic job of highlighting their many benefits, from improving soil structure to breaking down organic matter and providing valuable nutrients to plants. Thanks for sharing this informative and engaging article!
Thank you so much for saying so. I had such a good time researching and writing about them. I really feel like I’m in love with worms!
What a fascinating article on the benefits of worms in homesteading! I had no idea that worms could be so helpful in maintaining soil health and creating nutrient-rich compost. The article is well-written and informative, and the featured image is a nice touch. Overall, a great read for anyone interested in sustainable agriculture and homesteading. Do you have any other tips for incorporating worms into a homesteading operation?
Hi MurryMerch
I’ve read that the more species of worm you have, the better. Because different species burrow to different depths. But so far, I can’t find any info on any species other than red wigglers, night crawlers and red worms…at least not where one can obtain them. But I’ll keep looking.
Anna
Hey thank you for this post!
WOW! I had no idea worms were this useful, I always wondered what their use was in the environment. This pos that certainly got me wanting to learn more about these small and underrated creatures.
It is interesting to learn how baby worms are considerably stronger, I wonder what the reason for this strength is, do they have more to offer?
Thanks again and have a great day!
I know, right!
In researching this, I found myself falling completely in love with them. I too have been wondering about why the babies are so much stronger than the adults. I don’t know if I’m right, but my gut tells me it’s because they don’t have any bones. Those of us with bones, use our muscles to bend the joints. Since they have no joints, the muscle is simply pure pulling or pushing. And the babies, being so tiny, have this unbelievable strength concentrated…?
Like I said, I don’t know it this is right. But whether it is or not…omg!…they are so awesome!
As a keen gardener, I have always known that earthworms are very good for the soil, and therefore the plants. But it is amazing to see just how strong they are and how much soil they can move around.
My son bought a little “worm farm” to help my granddaughter learn about gardening and worms, and also how to attract butterflies and bees. The “farm” is a plastic tub that consists of a few layers, with a type of mesh, that the worms can move through. There is soil in there, and we give it some of the composting scraps from the kitchen, which the worms seem to love.
We then pour some water over it, and collect the water that runs through, which is full of nutrients and the best natural fertiliser. We use this special worm fertilised water to water our veggie garden and all the houseplants and potted plants, and they are thriving.
So earthworms are absolutely awesome. Not only do they enrich the soil, but it is a great way for kids to learn about natural and sustainable gardening methods.
They really are incredible, aren’t they? And it’s all underground and out of our sight.
I’ve admired them for a long, long time, too. But, in researching this article, I was totally amazed. There was just no end to the fascinating things to learn about them. (Had to split it up into two articles!)
I came across a cool quote, “To understand worms is to understand life,” and I plan on making a T-shirt design with it!
Sounds like your kids & grandkids are finding that out…which is fabulous! There is nothing better than hands on learning.
Thanks for your lovely comment,
xxoo,

This post about worms amazed me! Charles Darwin’s fascination with them led to the discovery of their earth-moving abilities. Earthworms can move eight tons of earth on just one acre per year, and their castings enrich the soil.
Despite their small size, they’re incredibly strong, pushing ten times their weight. These creatures exhibit intelligence without much brainpower, using sensory signals to navigate their environment. We should learn from worms’ humility and intuition to find peace in our hectic lives.
Yes!
I feel like worms are one of my totem animals. I appreciate them so much.
