A paper
published recently in the journal
Science finds similarities between the babbling of human infants and the babbling of the
greater sac-winged bat (
Saccopteryx bilineata) — a small species of bat that lives in Central and South America. As science correspondent
Geoff Brumfiel reports, the researchers believe both bats and humans evolved babbling as a precursor to more complex vocal behavior like singing, or, in the case of people, talking.
