Phobias may be memories passed down in genes from ancestors.

Memories becoming encoded in DNA. It sounds unbelievable but when you think about how animals just "know" how to do things it makes sense.

That does make sense but this is still an interesting thought:

It is possible for some information to be inherited biologically through chemical changes that occur in DNA.

Makes me wonder if people who suffer Post Traumatic Stress can pass it along to their kids. 

Perhaps all phobias are rational.

Researchers at the Emory University School of Medicine, in Atlanta, found that mice can pass on learned information about traumatic or stressful experiences – in this case a fear of the smell of cherry blossom – to subsequent generations. 

The results may help to explain why people suffer from seemingly irrational phobias – it may be based on the inherited experiences of their ancestors. 

In the study, which is published in the journal of Nature Neuroscience, the researchers trained mice to fear the smell of cherry blossom using electric shocks before allowing them to breed. 


I'm not 100% sure but I seem to remember that there has been some research around children of Holocaust victims. Their parents experiences certainly shaped them in the "nuture" sense but I think some research may have suggested a "nature"/ biological connection as well. Maybe this new research on phobias and changes in DNA will shed some light on that.

Thanks for finding that. Interesting, isn't it?

Yes, so glad you mentioned it!  Now reading  the internets for moar.  :)
