This crochet model is the shape formed for 1, 2, 4, 8, 16, 32, 64, 128, 256, 512. That is the shape of the web of ancestors for one single person, for 200 years, or 10 generations.
Extend that out further into 20,000 years and more.....
Multiply by the number of people on earth now.
There will be merging of ancestors for siblings.
Every time two people are married, there is merging of ancestral lineages.For that matter, there would be merging of ancestors each time two people have sex, especially if there is a child conceived.
From the previous population graph, there will be a limit to the number of ancestors possible. Somewhere further along is the Common ancestor, the UR mother and the UR father. My guess is that there may be more than one seed person ancestor, one for each human type group, eg asian, african, aboriginal, european, maybe siberian or from Altai Mountains area. DNA and deep ancestry investigations are interesting.
Are we One big family or a number of different families?

It seems as if the planet was seeded by a number of different races-----so I don't think we are related to everyone on the planet back in 1400s.........
The Tree of Life has many dead and broken branches.
Said by Charles Darwin.
So also has the Tree of Man. Plague, wars, famine and climate change has trimmed the tree over aeons. It is a miracle that we are still here. It is possible that we might discover a way to consciously make this a happy world that can live forever.
