According to a new concept by LMU chemists led by Thomas Carell, it was a novel molecular species composed out of RNA and peptides that set in motion the evolution of life into more complex forms.

Investigating the question as to how life could emerge long ago on the early Earth is one of the most fascinating challenges for science. Which conditions must have prevailed for the basic building blocks of more complex life to form? One of the main answers is based upon the so-called RNA world idea, which molecular biology pioneer Walter Gilbert formulated in 1986. The hypothesis holds that nucleotides—the basic building blocks of the nucleic acids A, C, G, and U—emerged out of the primordial soup, and that short RNA molecules then formed out of the nucleotides. These so-called oligonucleotides were already capable of encoding small amounts of genetic information.

As such single-stranded RNA molecules could also combine into double strands, however, this gave rise to the theoretical possibility that the molecules could replicate themselves—i.e. reproduce. Only two nucleotides fit together in each case, meaning that one strand is the exact counterpart of another and thus forms the template for another strand.

Does our planet have a mind and agency of its own? This is one of the main questions philosopher and mystic Oberon Zell illuminates in his latest masterpiece GaeaGenesis: Conception and Birth of the Living Earth. Just as we don’t see a bacterium with a naked eye, we don’t quite seem to have an innate ability to perceive the Gaian mind with a “naked” brain. As Dr. Ralph Metzner, Professor Emeritus of California Institute of Integral Studies and Founder-President of The Green Earth Foundation, writes: “Oberon Zell was the first person to conceive and publish the biological and metaphysical foundations of what has become known as the ‘Gaia Theory’ — the unified body and emergent soul of the living Earth… For over 50 years Oberon has been writing and lecturing on Gaian consciousness, and it is high time that he put it all together into a book!” And, indeed, he did.

The newly-released book takes the idea beyond the metaphorical realm postulated by James Lovelock in his “Gaia Hypothesis” and posits that the entire evolution of life on Earth is the literal embryology of a single vast living being — one replicating continuum of DNA and protoplasm. This distinction has significant implications for the subject of this book: The proposition that Mother Earth is a living, sentient being with a “soul” that humans can perceive if they are aware enough to sense it. In essence, the living beings that populate the Earth are cells within a greater macro-organism.

Here’s one of the revelatory passages from the book: To better understand the planet as a living system, we need to go beyond the time scales of human life to the planet’s own time scale, vastly greater than our own. Looked at in this way, the rhythm of day and night might be the pulse of the planet, one full cycle of every hundred thousand human heartbeats. Speeding up time appropriately, we would see the atmosphere and ocean currents swirling round the planet, circulating nutrients and carrying away waste products, much as the blood circulates nutrients and carries away waste in our own bodies.

New details of our past are coming to light, hiding in the nooks and crannies of the world, as we refine our techniques to go looking for them. Most lauded is the reconstruction of the evolution of humanity since our African origins around 300,000 years ago, by analyzing our living and fossil DNA.

Replete with the ghosts of African and Eurasian populations of the deep past, these have been resurrected only through the ability of science to reach into the world of the minuscule by studying biomolecules.

Now, digital analysis of rock surfaces reveals how other ghosts of the deep past – this time from almost 2,000 years ago in North America – have been coaxed into the light.

“The Earth has entered a radically new era, understood by scientists as the Anthropocene: a time when humanity reckons with massive geologic and biospheric forces we, as anthropos, have set in motion. The agency of Nature and the reality of humanity as a collective geologic force is becoming understood differently, even within the Western paradigm. It is a new world our children will inherit, for if humanity is to survive, we must come into new realizations of our place within the planetary life-support systems. To lay a path for future generations through the evolutionary steps that humanity must now take to learn to live in balance with the planet, science must come to balance with Spirit.” ―Oberon Zell, GaeaGenesis.

In the early 1970s, celebrated philosopher and mystic Oberon Zell was the first to propose the radical idea that the biosphere of Earth was a single living superorganism. His initial article on the subject electrified the emerging modern movement of Earth-based spirituality, generating volumes of correspondence, lecture tours, and further articles in various journals and books.

The excitement was the result of a simple yet profound idea. Imagine for a moment that Earth is alive. Not just teeming with living things, but a living, vital organism encompassing the whole of the planet. This is how Oberon Zell imagines it in GaeaGenesis 0, but it is more than imagination or mere metaphor. GaeaGenesis is the first work to fully integrate the mythological, spiritual, biological, and social history of what has become known as the Gaea Thesis. It builds upon this history by exploring the profound implications of the thesis, which is as significant to our understanding of the world and our place in it as the heliocentric theory of the solar system and Darwin’s theory of evolution once were.

This menagerie includes three spiral-shaped galaxies, an elliptical galaxy, and a lenticular (lens-like) galaxy. Somehow, these different galaxies crossed paths in their evolution to create an exceptionally crowded and eclectic galaxy sampler.

Caught in a leisurely gravitational dance, the whole group is so crowded that it could fit within a region of space that is less than twice the diameter of our Milky Way.

The Milky Way is the galaxy that contains the Earth, and is named for its appearance from Earth. It is a barred spiral galaxy that contains an estimated 100–400 billion stars and has a diameter between 150,000 and 200,000 light-years.

An analysis of the genetic material in the ocean has identified thousands of previously unknown RNA viruses and doubled the number of phyla, or biological groups, of viruses thought to exist, according to a new study our team of researchers has published in the journal Science.

RNA viruses are best known for the diseases they cause in people, ranging from the common cold to COVID-19. They also infect plants and animals important to people.

These viruses carry their genetic information in RNA, rather than DNA. RNA viruses evolve at much quicker rates than DNA viruses do. While scientists have cataloged hundreds of thousands of DNA viruses in their natural ecosystems, RNA viruses have been relatively unstudied.
