Summary
Scientists uncover a surprising genetic split in Western toads across Canada—Alberta toads boast vocal sacs and sing to attract mates, while their B.C. cousins stay silent and hunt for love. DNA tests reveal three distinct genetic clusters, including one in the southern Rockies likely extending into Montana. This evolutionary divergence, shaped over centuries by environment and risk, shows how nature’s quiet experiments are still unfolding right in our backyard. Next time you’re near wetlands, listen—those toad calls might be singing a song of survival across the mountains.
