How did life on Earth begin? Scientists have proposed various theoretical “worlds,” in which a single type of molecule, environment, or system led the story. But with each, there remain open questions. This week, we’re exploring some of the leading theories, and the new ideas borne from bridging them. Welcome to Origins of Life Week. 🧵
If you try to imagine the ancient cell from which all life on Earth evolved, you might assume it must be extremely simple. Think again. quantamagazine.org/all-life-… (From the archive)

For well over 4 billion years, the fire of metabolism has powered the engines of life. Might it have kickstarted the first life forms on Earth, as well? quantamagazine.org/what-is-t…
In Earth’s early days, particular conditions in water puddles may have encouraged the formation of tiny bubbles — life’s first protocells. Not all scientists agree. quantamagazine.org/the-case-…
Over and over, biochemists have found that when living cells use chiral molecules, they use one chirality exclusively. Why? (From the archive) quantamagazine.org/magnetism…
The rare meteorites called carbonaceous chondrites were found to carry traces of organic molecules, including amino acids. The discovery fueled theories that organic molecules from space might have helped start life on Earth. quantamagazine.org/inside-an… (From the archive)
Next up in Quanta’s Origins of Life Week: writer Perri Thaler explores whether early Earth was filled with life-giving bubbles. quantamagazine.org/the-case-…
Researchers have studied the phenomenon of introspection in humans and animals for over a century — and now they’re turning their attention to new subjects: large language models. Can they also look inside themselves? Tune into the latest episode of The Quanta Podcast: podcasts.apple.com/us/podcas…
In the 1960s, the molecular biologist Sol Spiegelman created a synthetic mutating strand of RNA and nicknamed it “the little monster.” His studies were the world’s first experimental demonstration of Darwinian evolution at the molecular level. quantamagazine.org/in-test-t…

RNA isn’t “alive” in itself. It’s easy to imagine, however, how early RNA molecules could evolve into forms that catalyzed metabolic processes. This may be the story behind Earth’s first living protocells. quantamagazine.org/did-life-…
“You have to watch out for your sanity in a field like quantum foundations,” said Lucien Hardy, a physicist at the Perimeter Institute. quantamagazine.org/a-strange…
How did the first cells get energy? Nick Lane, an evolution researcher at University College London, has proposed that porous, energy-rich geological environments may have supported the first metabolic biochemistry and coaxed cells to form within them. quantamagazine.org/a-biochem…

How did life first appear? It’s one of science’s biggest questions. One theory pins the start on self-replicating RNA. quantamagazine.org/did-life-…
Albert Einstein fought to save our everyday notion of reality from the strangeness of quantum mechanics. But those who set out to aid him keep poking holes in his argument.
