Memories may be passed down through generations in our DNA


New research from Emory University School of Medicine, in Atlanta, has shown that it is possible for some information to be inherited biologically through chemical changes that occur in DNA. During the tests they learned that 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.

  1. I've always suspected there had to be some other element at play in evolution other than pure Darwinian luck (random mutation + survival of the fittest). DNA memories are the only explanation that makes any sense when it comes to elaborately hard-wired instincts in animals. Like sea turtles knowing which direction to swim immediately after birth, or human babies knowing to hold their breath when submerged in water. I think we're just scratching the surface about how DNA recoding works in conjunction with the plasticity of the brain.
