Ghost in your genes...

We get our physical features from our parents. Similarly we acquire our behavior patterns from our parents. There was an interesting experiment that the scientists carried out.

There is a nurturing mother mouse say M1 who takes care of her children really well. There is another mother mouse, say M2, who is non-nurturing and neglects her children after the birth.

M1’s kids turn out to be quiet and well behaved and M2’s kids are nuisance, they bite people and scream and shout in the cage. Scientists placed M2’s newborns in M1’s cage and M1’s newborns in M2’s cage. Guess what? M2’s kids turned out to be quiet and well behaved and M1’s kids – nuisance!

That means all behavior patterns are not dependent on genes a lot relies on nurturing.

There is a small village in Sweden where people always faced famine (this was 100 years ago). Now their grandchildren are scared of even the word ‘famine’. (Though no one has faced famine in recent years) The fear of famine was passed on to the new generation through genes.

You can watch all this and more interesting stories in a documentary called ‘Ghost in your Genes’.

This documentary made me think what if like fear, even knowledge and information is passed through genes? A lot of times we feel ‘oh I have been to this place before’ – déjà vu – is it because some of our ancestors have experienced it in their lifetime? It would really have been great if the knowledge and information was passed on to the next generations through genes!

Nice documentary, you can find it on Google videos.
