Are fruit flies smarter than we thought?


Oxford University neuroscientists have shown that fruit flies take longer to make more difficult decisions.

In experiments asking fruit flies to distinguish between ever closer concentrations of an odour, the researchers found that the flies don’t act instinctively or impulsively. Instead they appear to accumulate information before committing to a choice.

Gathering information before making a decision has been considered a sign of higher intelligence, like that shown by primates and humans.
