Betül Kaçar started her scientific career as a biochemist, working on an enzyme found in zebrafish. But then she found her calling: investigating some of the hardest questions in evolutionary biology by resurrecting ancient life forms. NASA administrator Melissa Kirven-Brooks recalls the fellowship application that put Betül on her radar. And evolutionary biologist and geneticist Harmit Malik weighs in on what makes Betül's project so hard, and why he’s kind of jealous he didn’t think of it first. Betül previously received a Hypothesis Fund Award for her research.Guest:Dr. Betül Kaçar, professor at the University of Wisconsin-Madison and leader of a NASA-funded multi-institutional research center focusing on life’s early evolution“The Leap” is a 10-episode audio series that profiles scientists willing to take big risks to push the boundaries of discovery.
