How well does the Nash equilibrium concept from game theory map to the real world?
To discover our species’ deep history and to shape its future health, we should learn from the microbes that accompanied us on our evolutionary journey.
In applying game theory to biology and human behavior, have scientists focused too much on competition over cooperation?
Elephants did not evolve to become huge animals until after they turned a bit of genetic junk into a unique defense against inevitable tumors.
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.
Puzzle solvers rediscovered a simple mathematical result of Mendelian genetics and weighed in on a Richard Dawkins metaphor.
Mitonuclear conflict — a struggle between the genes in a cell’s nucleus and its mitochondria — might sometimes split species in two.
