Origin-of-Life Study Points to Chemical Chimeras, Not RNA
...work, published today in Nature Chemistry, highlights just how essential a diverse, complex blend of ingredients may have been to life’s earliest evolution. Bring On the Hybrid Monsters The narrative...
New Hybrid Species Remix Old Genes Creatively
...extent of hybrid ancestry in the genome has far outpaced our progress in understanding its evolutionary impact,” wrote Molly Schumer, an evolutionary biologist at Stanford University, and her colleagues in...
Where Quantum Probability Comes From
...constitutes a “measurement”? When exactly does it occur? Why are measurements seemingly different from ordinary evolution? Dynamical-collapse theories offer perhaps the most straightforward resolution to the measurement problem. They posit...
Bacterial Clones Show Surprising Individuality
...on an important evolutionary process. “This has been a relatively overlooked phenomenon,” said Hesper Rego, a microbiologist at the Yale School of Medicine. “The idea that microbial populations could evolve...
Fossil DNA Reveals New Twists in Modern Human Origins
...these events are happening all over the place,” said Aylwyn Scally, an evolutionary geneticist at the University of Cambridge. “But it’s very hard for us to pin down any particular...
Soil’s Microbial Market Shows the Ruthless Side of Forests
...evolution lab at the University of Minnesota. Along with Stuart West, an evolutionary theorist at the University of Oxford whom Kiers had met in Panama, she and Denison modeled the...
A Mathematical Model Unlocks the Secrets of Vision
...successful history of modeling changing phenomena, from the movement of billiard balls to the evolution of space-time. These are examples of “dynamical systems” — systems that evolve over time according...
Can New Species Evolve From Cancers? Maybe. Here’s How.
...like a life cycle,” Aktipis said. “There’s nothing special about the evolutionary process that says you can only evolve a life cycle if you are a branch of the evolutionary...
To Make Two Black Holes Collide, Try Three
...because of a triple-system process. If a black hole binary system formed through the evolution of two stars without the influence of other bodies, they should be rotating and orbiting...
