On the show this week we’re joined by Brian Butterworth, emeritus professor of cognitive neuropsychology and author of the new book Can Fish Count? What Animals Reveal About Our Uniquely Mathematical Minds. He’s spent his career looking at the genetics and neuroscience of mathematical ability—and not just in humans.  Support the show: https://www.patreon.com/inquiringminds See omnystudio.com/listener for privacy information.
