Who knew? Researchers from Queen Mary University of London have found that goats’ “accents” change as they grow older and move into different groups. The findings contradict claims that most mammals’ voices are entirely genetic. Previously only humans, elephants, dolphins, and a few other mammals were thought to be able to pick up accents. The scientists found that the calls of young goats raised in the same social groups were similar to each other, and became more similar as they grew older.
