PBS Digital Studios’ It’s Okay To Be Smart provides diverse science question-and-answer videos on YouTube. Released regularly throughout the month, the show is hosted by Joe Hanson, with topics like, “Why Do We Have To Sleep?" or “Why Are Cicadas So Good At Math?" and the controversial “Could We Clone Ourselves?" Hanson approaches what could be an overwhelming tidal wave of information with pluck and vim, firmly espousing that “we live in the future, and that future is one in which science impacts every part of our lives." In 2015, they released The 12 Days of Evolution series throughout December, answering common questions about evolution and natural selection.
