Genetic relatedness in sperm whales: Evidence and cultural implications

  • Sarah L. Mesnick (a1)
Abstract

Results of genetic analyses show that social groups of female and immature sperm whales are comprised of multiple matrilines as evidenced by the presence of multiple mitochondrial (maternally inherited) control region haplotypes. These data suggest: (1) a social environment in which the transmission of cultural information, such as vocal dialects, is more likely to be horizontal or oblique rather than strictly vertical (mother-offspring) and (2) lead us to question the data presented to support gene-culture coevolution.
