(Telegraph) Phobias may be memories passed down in genes from ancestors

Memories may be passed down through generations in DNA in a process that may be the underlying cause of phobias
Memories can be passed down to later generations through genetic switches that allow offspring to inherit the experience of their ancestors, according to new research that may explain how phobias can develop.
Scientists have long assumed that memories and learned experiences built up during a lifetime must be passed on by teaching later generations or through personal experience.
However, new research has shown that it is possible for some information to be inherited biologically through chemical changes that occur in DNA.
