It was thought that people in the west stopped marrying their close relatives in the 19th century, because improved transport meant that people were born further away from their families. But the family tree proved otherwise.
“Even though people started to be born further away from their families during the early 19th century, they were still marrying cousins for 50 years,” says Kaplanis. It seems the eventual decrease in inbreeding was more to do with cultural influences. “It just became less socially acceptable.”
