Evolutionary Arms Races

Shane explores the fascinating evolutionary arms race between rough-skinned newts and garter snakes, where the newts' production of tetrodotoxin serves as a defense mechanism against predation. Remarkably, garter snakes have evolved resistance to this potent toxin, with some populations being up to 1000 times more resistant than others. This dynamic showcases the beauty of biology and the intricate relationships that shape species survival.
