Matt James, Chief Animal Officer at Colossal Biosciences and an Oak Cliff neighbor, joins The Hidden City to unpack one of the most ambitious ideas in modern conservation: making extinction a thing of the past. We talk about how Colossal uses genetic engineering, AI, and assisted reproduction to revive keystone species like the woolly mammoth and dire wolf — and why rewilding has the power to restore entire ecosystems. Matt shares what functional de-extinction really means, the ethical questions that come with it, and how these breakthrough technologies are already helping protect at-risk species today. We also trade notes on our favorite walkable Oak Cliff spots and what makes this neighborhood feel like home.

Chris Corpus, Senior Director of Conservation and Community Impact at the Dallas Zoo, joins us to talk about what it really means to care for wildlife—both in faraway ecosystems and right here in Oak Cliff. From creek cleanups and community partnerships to wildlife rescue and international conservation work, Chris shares how his journey from journalism and filmmaking led him to a career centered on people, place, and protecting what’s wild. Along the way, we dig into urban nature, global species recovery, and why empathy and education are at the heart of it all.
