In some sense, instinct could be considered a form of memory from our ancestors. Instinct is carried on in the genes—so in that sense its genetic and it shapes your brain in a certain way. To that extent, it resembles memory, because its also the way of wiring the brain a certain way.
Do we have our ancestors memories?
Recent studies done by scientists and researchers even suggest that we receive loads of genetic memories from our parents, grandparents, and further ancestors, in an instinctive effort by their DNA to better prepare ours for difficult experiences that they have faced, such as fear, disease, or trauma.
How do instincts get passed on?
Instinct, by definition, is a hard-wired behavior. It does not have to be learned. Therefore, it is passed on from generation to generation. Therefore, it is encoded in DNA (as preconfigured neural structures?)
Can DNA contain memories?
Animal and human investigations indicate that the impact of trauma experienced by mothers affects early offspring development, but new research is also discovering that it is also actually encoded into the DNA of subsequent generations.
Is genetic memory a thing?
In contrast to the modern view, in the 19th century, biologists considered genetic memory to be a fusion of memory and heredity, and held it to be a Lamarckian mechanism. In modern psychology, genetic memory is generally considered a false idea. However, biologists such as Stuart A.
