I am closely related to myself and much more closely related than anybody else on this street.
“All the people outside Africa are closer related to EACHOTHER”
We are all 100% related to ourselves, unless we are a chimera. ;)
All told however we are a very homologous species, reflecting our recent common ancestry. We are a very young species and very similar to each other despite the obvious difference in skin color to balance vitamin D production with filtering out mutagenic sunlight.
I have long held that if your parents never had children you probably won't either.
