Family ties that bind: Maternal grandparents are more involved in the lives of their grandchildren
Date:12/18/2007

As families gather round for the winter holidays, some faces may be more familiar than others.

A recent study shows that the amount of social interaction between extended family members depends on whether people are related through their mother or father.

Thomas Pollet and colleagues at Newcastle University and the University of Antwerp, Belgium, investigated how far maternal grandparents and paternal grandparents will go to maintain face-to-face contact with their grandchildren. They found that maternal grandparents were willing to travel further in order to sustain frequent (daily or a few times a week) contact with their grandchildren than paternal grandparents.

Mr Pollet says, As the festive period approaches, we can still see that family get-togethers are integral to the celebrations. Many people will be going the extra mile to ensure they meet up and weve found thats particularly important if family members are related through mothers.

Even in families where there has been divorce, we found consistent differences grandparents on your mother's side make the extra effort. We believe there are psychological mechanisms at play because throughout history, women are always related by maternity whereas men can never be wholly certain they are the biological father to their children.

The authors interpret their findings as support for psychological patterns resulting from our evolutionary history. Family members related through their mothers (matrilineal kin) are predicted to matter more than those related through their fathers (patrilineal kin). Throughout human evolution, women were always related by certain maternity, whereas men could never be wholly certain that they are the biological father. Also, maternal grandparents were always more certain than paternal grandparents that a grandchildren was related to them. Thus, maternal grandparents, especially maternal grandmothers, may go the extra mile to visit their
