Meaning niggers are effectively a different species that can interbreed with humans, just like horses can interbreed with donkeys.
If humans would have descended from niggers, there would be a connection. It's clear that all humans (not niggers) have a common ancestry, even if it spans back thousands to millions of years back. If there is a connection, common ancestry would be so distant that it would span up to billions of years.
