-I usually think about lineages from the perspective of the ancestor. E.g. my
-grandpa had 5 kids; those 5 kids produced 9 grandkids; those 9 grandkids
-produced 3 great-grandkids (so far); 17 descendants in total.

-Over the last few days, I've been having fun thinking about the situation in
-reverse, from the perspective of the descendant. Here's a quote from *Genes:
-A Very Short Introduction* by Jonathan Slack:
-
-> Also, when considering 'roots', some of the basic mathematics of inheritance
-> needs to be borne in mind. With fully random matings the number of your
-> ancestors doubles every generation. Ten generations ago (250-300 years) we
-> might expect about 1,000 ancestors each contributing 0.1 percent of their
-> total variants to your genome... when the number of ancestors exceeds 
-> 2,000-3,000 (12 generations would be about 4,000), it is likely that some
-> ancestral sections of DNA have been lost altogether... by about 15
-> generations back many of the ancestors contribute no DNA variants at all but
-> they are still ancestors on the lineage. So, even though we all have an
-> ancestry running back to the origin of life on Earth, we do not necessarily
-> have any DNA variants from most of our ancestors.

-(In the [original version of this post] I did a thought experiment here to calculate
-when the number of ancestors starts to get nonsensical, i.e. if you double the
-number of ancestors every generation there's a point where the number of ancestors
-exceeds the total number of humans at that point. I've removed this thought experiment
-because I think it distracts from my main idea. See the [Hacker News discussion].)

-Your exact number of ancestors depends on how much [pedigree collapse] there
-is in your lineage, but I'm pretty sure the basic premise of this blog post
-holds: you've got a lot of ancestors.
