tl;dr the elephant in the room is that west africans are mixed with another species/sub-species that we know nothing about
---
for homo sapiens:
# subspecies
homo sapiens sapiens
homo sapiens idaltu (proposed, ethiopians)
# contested rank — subspecies or separate species
homo neanderthalensis
homo longi ("Dragon Man" aka denisovans)
# separate species, but debated
homo heidelbergensis
homo rhodesiensis
# separate species
homo floresiensis
homo luzonensis
homo naledi
# undetermined
"ghost lineage". there are no fossils of it, just population dna traces in africa that split 360k to 1M years ago - before Neanderthals - so very likely another species
---
+ every non african person has 1-2% neanderthal with East Asians having 20% more
+ oceania has 5% denisovan, east asians have 1%
+ west africans have up to 19% of the mystery ghost dna
