Of Mice and Men and Science

Did you see this  article in the news some time ago ?

I always love when science 'catches up' with the bible. After multiples tries and many discarded, amended, adjusted attempts at understanding  the world we live in and defining how things work, science does sometimes confirm the truth.

In Gen. 9:2 God says this .. "and the fear of you and the dread of you shall be on every beast of the earth, on every bird of the air , on all that move on the earth.... "   

I used to wonder how this could be since God originally created animals to be Adam's 'friends', yet something changed when God told Noah after the flood that, from then on, animals would fear man So how is it that today animals still  fear man, unless with patient retraining they are 'tamed'?
What happened that permanently changed the animals' instinctive trust of man to an instinctive fear of man?

Seems science has found the answer.

Using foot shocks lab mice were trained to fear a fragrance resembling orange blossoms.  To the surprise of the scientists somehow there was a transfer of information regarding the 'danger' of this fragrance into the sperm of the trained mice.
This ensured that the 'fear'  response to that particular scent  was passed on to their young.   The other surprising result was that the successive generations had an even greater fear response to the 'smell' and needed a smaller amount of fragrance to trigger the response.

Interesting to note, isn't it, that  next time a wild animal flees from you in fear you can know that it is still displaying something learned by its ancestors that lived in Noah's time. It  is literally the 'smell' of man that triggers the fear of man in animals, just as the mice in the quoted experiment were trained by a 'smell'.

God's word is true, and it is always true, no matter how long it takes science to figure something out!!

I was wondering ....
God says in Duet. 5:9 that the iniquity of the fathers is passed down to the children, to the third and fourth generations.  BUT those who love God and keep His commandments experience God's mercy.
We have indication in our language usage  that people are aware of this 'passing down' - from parent to child - of characteristics , behavior patterns, addictions etc.
Familiar phrases are .. "Like father, like son..."  or "he's a chip off the old block" , or "that's a family trait".

From the initial brainstorming work of two scientists, Moshe Szyf, a moecular biologist and geneticist at McGill University in Montreal, and Michael Meaney, a McGill neurobiologist,  there spawned a whole new field, behavioral epigenetics.   This study has shown that our DNA is permanently changed by what we experience in our childhoods - negative or positive -  be it abuse or deprivation or loving affirmation.  

While God meant it for our good -- that our DNA would carry in it the pattern of the good example our parents modeled before us, so that it would be easier for us to 'do and live right' -- it also works against us if less than a good example is lived out by our childhood caregivers. Then our DNA is changed to follow a negative pattern, and we follow our parents'  tendency toward depression, or violence or anxiety. 
   
But isn't it reassuring, and comforting to know that all negative patterns that affected us in our growing up years  can be overturned by God's grace? 
 If we look to Him as our Savior, we are given a new start, we are a new creation, and are given a new example to follow.   Jesus  showed us the way,  He expressed God's love toward us, and when we come to Him in our brokenness,  He heals our hearts minds and spirits.
He gives us a new identity and  writes HIS DNA on our hearts.  


"I will give you a new name..."
 Isa_62:2 
 "I will give you a new heart and put a new spirit within you;
 I will take the heart of stone out of your flesh and give you a heart of flesh." 
Eze_36:26

DNA studies amaze me! Thanks Julie.
