Corina Tarnita deciphers bizarre patterns in the soil created by competing life-forms.
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.
How well does the Nash equilibrium concept from game theory map to the real world?
In applying game theory to biology and human behavior, have scientists focused too much on competition over cooperation?
Which mattered first at the dawn of life: proteins or nucleic acids? Proteins may have had the edge if a theorized process let them grow long enough to become self-replicating catalysts.
Minor genetic changes can have big evolutionary consequences. When a gene duplication gave some water striders a novel leg part, it opened up a new world for them.
Studies of the energy-harvesting proteins in primitive cells suggest that key features of photosynthesis might have evolved a billion years earlier than scientists thought.
