Very interesting thought. I reckon the average length of mother-child generations is nearer 28 than 25, which skews things a bit. You can very crudely approximate population growth from global 500 million in 1500 to global 7 billion in 2012 as an annual increase of 0.52%, 13.75% per 25 years, 15.53% per 28 years. (Of course this is unrealistic as the big surge is in the last 250 and especially the last 100 years.)
I’d be interested to see what you think, but my gut feeling is that an expanding population will keep some matrilineal descents in play longer than they might otherwise have been.
Hmmm, will look into this a bit more…
