It may seem frustrating to have so many imperfect competing hypotheses, but that’s part of the joy of chins: They reveal something about how scientists think about evolution. Some see the sculpting power of natural selection in everything, and view chins as surely some kind of adaptation. Others see natural selection as just one of many evolutionary forces, and so gravitate towards a spandrel-based explanation. “The chin is one of these rare phenomena in evolutionary biology that really exposes the deep philosophical differences between researchers in the field,” says Pampush.
More protein than beef. More omegas than salmon. Tons of calcium, antioxidants, and vitamin B. In their secret R&D lab, the scientists at Beyond Meat concocted a plant-protein-based performance burger that delivers the juicy flavor and texture of the real thing with none of the dietary and environmental downsides.
The psychology of accurate intuition involves no magic. Perhaps the best short statement of it is by the great Herbert Simon, who studied chess masters and showed that after thousands of hours of practice they come to see the pieces on the board differently from the rest of us.
