Theory is (I am going to get blasted for this one) that when we traveled in "packs" (prehistoric) having the females of the pack in sync as far as their reproductive cycle was concerned helped the viability of the offspring. There would be multiple matings during the fertile time and multiple births to the pack at the same time. That way if one female died during birth there would be a milking female to rear the young. Likewise if an infant died at birth or shortly there after as often was the case then there would other young needing care by the surviving female. The same phenomenon can be seen in many pack animals.
OR it may just be God's way to make sure we are all in a crappy mood at the same time. ;-)

One study showed that women smelling the sweat of other women (transferred using cotton balls) caused them to synchronize their periods.
