Resumen de Nest in show
Flying a state-of-the-art drone over a home to spy on its owners' taste in decor is usually frowned on. Fabrizio Sergio and his team, however, had a good excuse. The homes in question were nests belonging to birds of prey called black kites. Their decoration style? Tatty white plastic bags. In some cases, lots of them, making the nests as conspicuous as a reindeer on your front lawn or a plastic Santa climbing onto the roof. It might seem odd to talk about nests in terms of natural selection: after all, they aren't part of a bird's body, which is the obvious product of its genes. But 35 years ago, biologist Richard Dawkins suggested that a gene's influence could reach beyond the body that houses it and manipulate its environment--a phenomenon he called the extended phenotype. Structures built by animals, such as beaver dams and birds' nests, are a good example.
