I'm not saying that there's no innate knowledge. This entire list of reflexes https://en.wikipedia.org/wiki/List_of_reflexes is essentially a list of innate knowledge in humans, many of which have been demonstrated in newborns, apparently without considering such experiments unethical.

I'm saying that there are limits to how much knowledge can be inherited. I.e. the question isn't "Where could innate knowledge be encoded other than in synapses?" but "Considering the extremely large number of synapses involved in complex behavior far exceeds genetic storage capacity, how are their weights determined?" And since we know that in addition to having innate behaviors, animals are also capable of learning (e.g. responding to artificial stimuli not found in nature), it stands to reason that most synapse weights must be set by a dynamic learning process.
