Compiling and validating 86 million public profiles from Geni. The largest tree consisted of 13 million people, spanned an average of 11 generations and included both Sewall Wright , a founder of human population genetics, and the actor Kevin Bacon the two are separated by 24 degrees, in case you were wondering.
The study is the latest example of scientists using big, crowdsourced data collected by private companies to do research.
