*Fascinating*
“A photographer has been collecting pictures of human "lookalikes" for over 20 years. Spotting an opportunity, scientists recruited several of them to participate in a study. The volunteers provided DNA samples and answered questions about themselves. The researchers found that humans who look alike have similar genetic profiles and even display similar behaviors, such as smoking.”

@askennard A fascinating question. I wonder how they determined / identified physical similarities.
