Can even the strongest human climber match a mountain goat on the world’s toughest rock faces? In a new episode of CBC's The Nature of Things, Dr. Aaron Shafer, an evolutionary biologist and professor of Forensic Science at Trent, draws on two decades of mountain goat research to explore the extraordinary adaptations that make these animals elite climbers, from specialized hooves and powerful upper bodies to instinctive route-finding on near-vertical cliffs. Professor Shafer helps unpack the science behind nature’s climbing champions as they go head-to-head with grip strength world champion Yves Gravelle in a friendly battle of evolution versus training.
