Journey through millions of years of plant evolution with paleobotanist Dr. Aaron Pan, who unearths fascinating stories locked within fossilized leaves, fruits, and seeds from Earth's distant past. As Executive Director of the Museum of Texas Tech University, Dr. Pan bridges the worlds of scientific research and public education, sharing how ancient plant remains challenge our understanding of modern ecosystems.

Prepare to have your assumptions about plant origins completely upended. Did you know eucalyptus trees – quintessentially Australian icons – likely originated in South America? Or that Africa once had thriving palm forests despite hosting fewer palm species today than tiny Singapore? Dr. Pan's research in Ethiopia reveals evidence of lush, palm-filled landscapes that existed 21-27 million years ago, before continental collisions dramatically reshaped Earth's biodiversity.

The conversation explores how paleobotany differs from other paleontological disciplines, with plants presenting unique challenges since their various parts – leaves, flowers, fruits – can be scattered and fossilized separately. We delve into the collision of Africa with Eurasia that introduced zebras, giraffes, and lions to the continent, fundamentally altering both plant and animal communities in ways that continue to influence modern ecosystems.

Beyond the science, Dr. Pan offers insights into museum work and the importance of preserving both specimens and knowledge. With 9.5 million items in its collection, the Museum of Texas Tech stands as the 19th largest natural history collection in America. Whether you're fascinated by ancient plants, curious about how continents shape evolution, or simply love museums, this episode invites you to appreciate the incredible depth of time and the long, winding journey of plant life on our planet.
