Scientists in Oxford train fish to discriminate between human faces even though they lack a part of the brain that mammals and birds use for this task. The researchers are studying how human facial recognition has evolved. They say it means fish have a good memory. Valerie Sanderson asked Dr Caitlin Newport from Oxford University how they carried out the research
