Tell that to tits who now teach each other how to open milk bottles, or to the remaining uncivilised tribes who teach their kids the same things their ancestors have taught for generations.
The observation that what is being taught is pretty consistent over generations is a comment on how quickly environments change, not on fundamental differences in teaching habits. It's very obvious humans also teach their children to be just like them; possibly to even greater extents than most other animals, due to memetic reinforcement.
