Businessman and GOP candidate Paul Nehlen has been accused of racism after superimposing a picture of a black ancient Briton onto a picture of Meghan Markle.
"Get a life", he tweeted.
Researchers from the University College London explained earlier this month that DNA testing on Britain's oldest, almost complete human skeleton - dubbed Cheddar Man - revealed he had dark skin, blue eyes and dark curly hair.
"Way above your weight class".
"Publishing an article disappearing whites or dispossessing whites of their homelands is wrong; made worse when claiming "science" to "prove" whites never existed", he reportedly said. "Much love." Fans were quick to comment on the image, with one writing, "This is so cute", while another said: "Made me cry".

Second, the challenges that lie ahead for any kind of bilateral advance on the South China Sea should not be underestimated. He noted that the overall situation in the South China Sea "has become more stable than in past years".
Nehlen's account has since been suspended amidst additional anti-Semitic tweets.
"I am a member of the Republican Party regardless of what their traitorous, spineless apparatchiks believe", Nehlen said.
Nehlen is running to replace House Speaker Paul Ryan (R-Wis.), who he ran against in 2016 with the support of White House chief strategist Steve Bannon.
A facial reconstruction of the remains of Cheddar Man, whose skeleton was found in Gough's Cave in Somerset, was conducted by DNA specialists from the Natural History Museum and University College London.
After having boosted him to national prominence to defeat Mr. Ryan, the conservative and anti-establishment Breitbart news site already had washed its hands of Mr. Nehlen.
Twitter suspended Nehlen's account after he shared an image of Prince Harry standing next to Markle, a biracial American he is set to marry in May. The findings suggest lighter skin pigmentation now seen as typical of northern Europeans is far more recent than previously thought.
