EXCERPT: [...] In short, maladaptive pairings don’t tell the full story of interbreeding. The genetic transfer that takes place between organisms while their lineages are diverging has a hand in the emergence of adaptive traits and in the creation of new species altogether. According to Arnold, not only is it common for newly emerging species to reacquire genes through hybrid populations, “but it’s probably the most common way evolution proceeds, whether you’re talking about viruses, plants, bacteria or animals....”

EXCERPT: “These tests at their best allow new forms of connection that might not have been otherwise possible,” says Alondra Nelson, president-elect of the Social Science Research Council. Though African American communities experienced a troubled history with genetics, primarily through eugenics, individuals are now using DNA testing to answer questions about their ancestors and connect with their African heritage. Interviewed at the 2017 Aspen Ideas Festival, Nelson discusses how biology can provide information once lost through the transatlantic slave trade....
