News Finding: In the first study to compare the gestural repertoire of human infants to those of other apes using a directly comparable methodological approach, researchers found that 89% of the gestures used by human infants were present in the chimpanzee repertoire. 
Paper Finding: The single use cases would not normally be included in a gestural repertoire, see above, but are included here for completeness given the small data set.
News Context: In the first study to compare the gestural repertoire of human infants to those of other apes using a directly comparable methodological approach, researchers found that 89% of the gestures used by human infants were present in the chimpanzee repertoire. 
Paper Context: However, 7 of these were only coded as used in intentional communication on a single occasion, and the other 4 on n = 2 occasions. The single use cases would not normally be included in a gestural repertoire, see above, but are included here for completeness given the small data set. Given both the correlation between frequency of gesturing and number of gesture types used described above, and the correlation between the number of times a gesture occurred in a child's repertoire and its frequency in the data set (Pearson's correlation, r = 0.80, n = 51, P < 0.0001), the individual repertoires and the frequency with which a gesture was used by different children appear to be determinedly largely by sample size in our data.
