← Insects are scared to death of fish

As the insects were not harmed themselves and didn't see any of the others harmed, they must be born with the fear of fish. It is already known that certain new born geese can identify the shadow of a predator bird from that of a harmless type.

Does this not imply that there is such a thing as "memories" which are inherited within a species by some means we are unaware of that are much more nuanced than simple instinct? It seems far fetched that there are genes that "know" the threat posed by other creatures.
