This might be because females need more energy to birth and wean offspring Mann et al.
In teaching, as opposed to purely observational learning, the teacher modifies its behavior to better transmit information to the target.
Previous theoretical modeling suggests that uniparentally transmitted cultural traits can only be maintained in a population if the trait has a sufficiently high reproductive benefit or if the trait is independently innovated with sufficient frequency Enquist et al.
In the following model descriptions, I assume that uniparental care is provided by females and cultural traits are transmitted only through mothers by teaching or observational learning.
The reason for sex-biased transmission is a puzzle because many of the transmitted behaviors would be beneficial to both sexes.
The former mechanism seems important in maintaining sponging behaviors in the Shark Bay dolphin population Kopps and Sherwin as it seems to be transmitted primarily from mothers to offspring.
