There is also evidence of Epigenetic Memories, memories that are genetically encoded and passed from generation to generation.

  So my understanding of epigenetic changes generally is that they're changes in gene expression that last beyond a single cell generation, and sometimes beyond a single organism generation. When people talk about "Epigenetic Memories," they're using a bit of a romantic term for changes in gene expression that last beyond a single generation - for instance, a mother experiences a drought or famine that causes changes that can be detected in her offspring.

    This is interesting article; https://www.scientificamerican.com/article/fearful-memories-passed-down/ https://www.scientificamerican.com/article/fearful-memories-... and it is a reason I said some evidence. I am cautions my self not to be romantic about this topic, but at same time neural development is not random structure of cells and arguably brain has predispositions to behaviors. There is possibility that some genetic mutations over single generations are not strictly random, furthermore such genetic mutations specifically evolved over millions of years to introduce changes to environmental pressure. (this is only my speculation of course)
