“Earthdance”: for Gaia geeks
This blog is in love with Gaia. The living body of planet has swallowed me and will never disgorge me. The greatness which contains all of us as mere microbes within its vast body humbles and elevates me simultaneously.
You want meaning in your life? Look no further.
I highly recommend an online book called ‘Earthdance: Living Systems in Evolution’ by Elisabet Sahtouris. Another title of note in this genre is ‘Animate Earth: Science, Intuition and Gaia’ by Stephan Harding. There are books by James Lovelock and Lynn Margulis and others as well.
What distinguishes ‘Earthdance’ (in addition to its utter freaking cool amazingness) is its availability . You can read it online, here. That makes it very quotable too, which I am about to do. At length. For the Gaia geeks out there (surely I’m not the only one).
Here are some highlights from my recent reading in Chaps 5 and 6:
On life as rock rearranging itself (’This wood is my father, this stone gave me birth‘)
Vernadsky called life “a disperse of rock,” because he saw life as a chemical process transforming rock into highly active living matter and back, breaking it up, and moving it about in an endless cyclical process. Vernadsky’s view is presented in this book, as we say life is rock rearranging itself — like music come alive — packaging itself as cells, speeding its chemical changes with enzymes, turning cosmic radiation into its own forms of energy, transforming itself into ever-evolving creatures and back into rock. This view of living matter as continuous with, and as a chemical transformation of, nonliving planetary matter is very different from the view of life developing on the surface of a nonliving planet and adapting to it.
On life operating itself intelligently without conscious supervision:
We seldom reflect on the fact that our bodies work without asking anything of our aware, thinking minds. We need not even know consciously what is going on, much less having to think or plan or do anything about it. And a good thing this is, because we would most certainly mess up our bodies’ wonderful work if we interfered in it in an attempt to control it ourselves. Lewis Thomas, the popular science essayist and physiologist mentioned earlier, has said that for all his physiological knowledge, he would rather be put behind the controls of a jumbo jet than be put in charge of running his liver. Any one of our organs is more complicated by far than the most complicated computer we’ve invented, yet it knows how to run itself, repair itself, and work in harmony with all other organs. ….
The sooner we recognize and respect Gaia as an incredibly complex and demonstrably intelligent self-organizing living being, the sooner we will gain enough humility to stop believing we know how to manage her. If we stay on our present course, clinging to our present belief in our ability to control the Earth while knowing so little about it, our disastrously unintelligent interference in its affairs will not kill the planet, as many people believe, but it may very well kill us as a species, as we are already killing so many others.
On the likelihood of life on other planets:
Earth, it now appears — though we still search — is the only planet or moon in our solar system that had just the right size, density, composition, fluidity of elements, and just the right distancing and balancing of energy with its Sun star and satellite Moon to come alive and stay so. Yet its life is a result of this fortunate confluence of conditions, just as the development of a plant or animal embryo is. Our living Earth is likely no more a freak accident than is the seedling that grows or the frog egg that matures. All are the inevitable result of right compositions and conditions.
Some scientists believe the conditions of Earth were so special that Earth is a rare phenomenon, perhaps the only such planet in the universe. But there is no better reason to believe this than there is to believe that living planets are as common in the universe as are the successful seedlings and hatchlings of Earth. And if this is so, there are billions, maybe trillions, of other live planets in the billions of galaxies, each with their billions of star systems. Surely we are not alone.
On the influence of living organisms on the composition of the planet:
Thus the molecules in virtually all of the atmosphere, all of the soils and seas, all of the surface rocks and much of the underlying, recycling magma, have been through at least one phase in which they were within living creatures! It is easier to distinguish between life and death than between the domains of life and non-life we have assigned to biologists and geologists, respectively. In fact, virtually every geological part or feature of Earth we can find is a product of our planet’s life activity. Further, living organisms have invented 99.9 percent of all the kinds of molecules we know, almost all of them back when bacteria were the only creatures around, a few billion years ago.
on the potential swiftness of evolution from aggression to co-operation (some hope for us):
Rather vicious breathers can still be found drilling their way into other bacteria to reproduce there and eat the host bacteria from the inside. In the Tennessee laboratory of Kwang Jeon, protist hosts so invaded learned to tolerate and then to cooperate with their invaders in a mutually dependent relationship that brought about a new kind of creature. Surprisingly, this replay of the ancient evolutionary shift from outright aggression to full cooperation happened in only a few years’ time.
on the role of co-operation in evolution:
Margulis’ discovery, that eukaryote protists evolved cooperative internal schemes to overcome the problems caused by competition among prokaryote bacteria, was almost as much a shock to the world of science as was the Gaia hypothesis itself. Besides showing that cell `mechanisms’ such as mitochondria are creatures in their own right, she was suggesting that harmonious cooperation played a big role in evolution. This ran counter to the beliefs stemming from Darwin’s work, adopted by scientists in western countries, that evolution was just a survival race driven by competition.
Now, that is what I’m talking about.
Hallelujah!! Spreadin’ the Gaia word…
