Not necessarily more, but a different kind, apparently:

Linked NIH paper wrote:Interestingly, a similar mutational event in the primate AVPR1A may have contributed to the evolution of primate social behaviour. Humans and bonobos, both known for high levels of social reciprocity, empathy and sociosexual bonding, have a repetitive microsatellite locus 3625bp upstream of the transcription start site. In contrast, this microsatellite locus is absent in the common chimpanzee, reminiscent of the genetic differences between highly social and asocial voles at this locus.
