Hi Nadine Carroll; Re: "It would be utterly fascinating to trace with certainty any one human's ancestry for 50,000 years, wouldn't it?"

Since a typical human generation is about 20 years, that would be something like 2500 generations. In other words, going back that far you'd have something around 2^2500 = 10^752 different spots to fill. Of course almost all of them would be duplicates, cousins breeding with cousins.
