The ability to tell individual faces apart was long thought to be exclusive
to large-brained mammals. But in recent years a number of studies have shown
that, in fact, some wasps can facially recognize one another. And honeybees can
learn human faces, too.
In their article in the December issue of Scientific American, biologists
Elizabeth Tibbetts of the University of Michigan and Adrian Dyer of RMIT
University in Melbourne describe these findings and what they reveal about the
neural requirements for seemingly complex cognitive tasks.
