| | |  | The origins of the neural underpinnings of language are controversial. A study by Ricardo Gilda-Costa and colleagues suggests that the neural substrate for human speech evolved from an ancestor common to humans and macaque monkeys. The authors used PET imaging in macaque monkeys to find activity specific to macaque vocalizations in monkey brain areas homologous to human perisylvian language areas. The cover shows an image of a macaque monkey, which shared a common ancestor with humans 25-30 million years ago. Photo credit: Marc Hauser. (p 1064)
