Tori Herridge on ancient dwarf elephants and frozen mammoths

Author: BBC Radio 4 March 25, 2025 Duration: 28:39

Elephants are the largest living land mammal and today our planet is home to three species: the African bush elephant, the African forest elephant, and the Asian elephant.

But a hundred thousand years ago, in the chilly depths of the Ice Age, multiple species of elephant roamed the earth: from dog-sized dwarf elephants to towering woolly mammoths.

These gentle giants' evolutionary story and its parallels with that of humankind has long fascinated Dr Tori Herridge, a senior lecturer in evolutionary biology at the University of Sheffield, where - as a seasoned science broadcaster - she's also responsible for their Masters course in Science Communication.

Tori has spent much of her life studying fossil elephants and the sites where they were excavated; trying to establish facts behind relics that are far beyond the reach of Radio Carbon Dating. To date she's discovered dwarf mammoths on Mediterranean islands, retraced the groundbreaking Greek expedition of a female palaeontologist in the early 1900s, and even held an ancient woolly mammoth’s liver. (Verdict: stinky.)

But as she tells Professor Jim Al-Khalili, this passion for fossil-hunting is not just about understanding the past: this information is what will help us protect present-day elephants and the world around them for future generations.

Presented by Jim Al-Khalili Produced for BBC Studios by Lucy Taylor


Hosted by physicist and author Professor Jim Al-Khalili, The Life Scientific offers a rare and intimate glimpse into the minds shaping our world. Each conversation moves beyond the standard lecture or interview, weaving together personal history with groundbreaking ideas. You’ll hear how childhood curiosity, unexpected setbacks, and moments of sheer luck have steered the careers of some of today's most influential researchers. This BBC Radio 4 podcast treats science not as a remote collection of facts, but as a deeply human endeavor driven by passion, perseverance, and sometimes, serendipity. The discussions delve into the real process of discovery-the late-night frustrations, the collaborative breakthroughs, and the ethical questions that arise from new knowledge. While exploring everything from the smallest particles to the vastness of the cosmos, the core of each episode remains the individual behind the science. Listeners come to understand not just what these scientists know, but who they are and what continues to drive them forward. It’s a series that connects the personal to the universal, making complex fields accessible and profoundly relevant. By focusing on the life as much as the science, this podcast reveals how our future is being built, one question at a time, in labs, field stations, and offices around the globe.
