Since 2008, Big Think has been sharing big ideas from creative and curious minds. Since 2015, the Think Again podcast has been taking us out of our comfort zone, surprising our guests and Jason Gots, your host, with unexpected conversation starters from Big Think’s interview archives.Jennifer Doudna is a Professor of Chemistry and of Molecular and Cell Biology at the UC Berkeley, and until around 2012 she was quietly and contentedly studying the three dimensional structure of RNA molecules. Then she and her colleagues started looking into a thing called CRISPR-Cas9. It’s a kind of bacterial immune system, and it led to an invention that will change everything for all of humanity, forever. In this episode Jennifer and Jason discuss the implications of the gene editing tool her lab created, and how humanity should (and likely will) yield the power to rewrite our own evolutionary destiny.
