Knowledge transfer over generations is a function of the brain.
Other species have much more limited ability to transfer knowledge intergenerationally, and that is because the human brain's capability for symbolic language is much more advanced than other animals', who are not able to encode knowledge nearly as efficiently.
Sure but that's still only possible for the human brain, other species brains aren't capable of encoding knowledge and using that to collaborate with other members.
