Now obviously that doesn't mean you are a direct descendant of everyone who was living on the world at that point in time as you will start to get overlapping grandparents within a few generations back

Believe it or not, this kind of stuff has all been mathematically modeled before. Watch this;

The Earth has a heartbeat. Since the 60s seismologists have been able to pick up a pulse that reverberates around the planet every 26 seconds.
They don't know what causes it but they do know that it originates somewhere in the south-Atlantic Ocean.
