Interesting but a familiar subject. I'll look to see if it's 1,280
individual or 1,280 matrilineal lines...
Individuals, but:

[2015]: The fact that virtually every non-African mtDNA lineage derives
from just one of the two sub-clades of the African haplogroup L3 (Figure
2) has been interpreted as an evidence of a major bottleneck of mtDNA
diversity at the onset of the out of Africa dispersal. The magnitude of
this bottleneck has been estimated from the whole mtDNA sequence data
yielding the estimates of the effective population size which range
between several hundred and only few tens of females.
Maybe it's our time to step aside for the next major evolution in humans.
The Denosovans and Neanderthals had their chance.
And maybe the alien genetic overlords are really pumping the methane.
Congrats. You've caught up to Theodore Sturgeon's 1971 short, Occam's
Scalpel.
