How Dinosaurs Shrank and Became Birds
...genetic changes. Rather, Abzhanov showed that the same forces that shape microevolution — minor alterations within species — also drive macroevolution, the evolution of whole new features and new groups...
The Particle That Broke a Cosmic Speed Limit
...window into the laws of physics at otherwise unreachable scales — maybe even connecting particle physics with the evolution of the cosmos as a whole. At the very least, they...
A Surprise for Evolution in Giant Tree of Life
...reason scientists are skeptical is that Hedges’ clocklike pattern conflicts with the traditional picture of how evolution unfolds. “The classic view of evolution is that it happens in fits and...
How Quantum Pairs Stitch Space-Time
...where long-term predictions require powerful computers to simulate an approximation of the system’s evolution. In general, the more objects in the system, the more difficult the calculation, and that difficulty...
How Structure Arose in the Primordial Soup
...any of these remarkable biological innovations came about. “It’s very hard to infer even the relative ordering of evolutionary events before the last common ancestor,” said Greg Fournier, a geobiologist...
Did Neurons Evolve Twice?
...study, he thinks he knows why. According to traditional evolutionary biology, neurons evolved just once, hundreds of millions of years ago, likely after sea sponges branched off the evolutionary tree....
Strange Stars Pulse to the Golden Mean
...a system’s initial state had a proportionally small effect on its resulting fractal journey through its attractor, making its evolution relatively stable and predictable. The future path of a chaotic...
Killer Virus Is Invading Koala DNA
...into the germ-line genome isn’t unusual on evolutionary timescales. All vertebrates harbor retroviral DNA, molecular relics of infections from the distant past. Human genomes are made of about 8 percent...
Game Theory Calls Cooperation Into Question
...Stewart. The work is entirely theoretical at this point. But the findings could potentially have broad-reaching implications, explaining phenomena ranging from cooperation among complex organisms to the evolution of multicellularity...
