You’ve made the assumption that everyone has a unique pair of parents. You’ve not taken into account that parents can have multiple children.
One of the reasons behind the population boom (but not the only reason by any means) is that infant mortality is so low nowadays. Not that long ago, you could have entire families wiped out by diseases that are now functionally eradicated or easily treatable.
If you assume two children per group of parents survive until adulthood, the population line stays stable. It’s because of the massive rise in the number of children reaching adulthood that the population spikes so suddenly.
No that’s not the assumption I made. I said if one living person today had unique parents all the way back. Why would I have to take into account siblings if I’m only looking at the direct lineage.
I also said it’s impossible and inbreeding and pedigree collapse occurred.
