This was my first though too. Something happened, but it was not memory transfer. However RNA and biological indicators like hormones could (and probably do) have a big effect on learning, in terms of how fast we learn, how aware to be, feedback mechanisms, triggering long-term memory formation etc. The idea of storing memories in genetic materia has been really popular for a long time, but imo this is mostly due to either hope/belief for immortality and romantic trans-generational memory transfer, or new age trends. Of course it's not impossible, but it's very unlikely.
