Resumen de Sting in the tail
A willingness to draw parallels between mammals and insects is raising significant ethical questions about how people ought to treat them. In May, researchers in Sydney, Australia, suggested that the main part of the insect nervous system works in a similar way to a mammal's midbrain, and might provide the capacity for the most basic form of consciousness, subjective experience. Now a group in London says that bumblebees appear to show "positive emotion-like states". Singer comments that this would raise questions about the ethics of bee research.
