All of these people are twins! My favorites are the Durrants who have 2 sets of twins that look so much alike in everything except their skin color. Genetics, man.
Which just goes to show you how extra super bullshit racism is and how race is more social construct than science. They might not be identical twins but as siblings they’re genetically very, very similar and just the tiniest quark of genetics can mean a darker skin color. We are all so genetically similar as a species it is not even funny.
