In one Asian termite species, queens choose to shut their mates out of the picture when it’s time to breed a successor. They simply clone themselves to make new queens. To keep the king’s genes away, the queen makes special eggs that have no entrances for sperm—all their drawbridges are pul... mais »

Basta ler as manchetes e circular por aí. Nosso comportamento é ainda muito selvagem, violento, predador, ladrão e irracional. No caminho da evolução, ainda estamos engatinhando e com instintos muito primitivos, inadequados para o tipo de vida que afirmamos ser nossa escolha: civilizada, doméstica e cada vez mais urbana. A evolução, a seleção natural e a adaptação das espécies t... mais »
