In Birds’ Songs, Brains and Genes, He Finds Clues to Speech
The neuroscientist Erich Jarvis found that songbirds’ vocal skills and humans’ spoken language are both rooted in neural pathways for controlling learned movements.
A Domesticated Dingo? No, but Some Are Getting Less Wild
Near an Australian desert mining camp, wild dingoes are losing their fear of humans. Their genetic and behavioral changes may echo those from the domestication of dogs.
With ‘Downsized’ DNA, Flowering Plants Took Over the World
Compact genomes and tiny cells gave flowering plants an edge over competing flora. This discovery hints at a broader evolutionary principle.
Is a Bigger Genetic Code Better? Get Ready to Find Out
Evolution settled on a genetic code that uses four letters to name 20 amino acids. Synthetic biologists adding new bases to DNA will be free to improve on nature — if they can.
A Mathematician Who Decodes the Patterns Stamped Out by Life
Corina Tarnita deciphers bizarre patterns in the soil created by competing life-forms.
New Bird Species Arises From Hybrids, as Scientists Watch
The rapid, unorthodox emergence of a new finch in the Galápagos hints that speciation isn’t rare. New hybrid species may quietly appear and disappear without anyone noticing.
Solution: ‘Triumph or Cooperation in Game Theory and Evolution’
How well does the Nash equilibrium concept from game theory map to the real world?
How to Triumph and Cooperate in Game Theory and Evolution
In applying game theory to biology and human behavior, have scientists focused too much on competition over cooperation?
