Wild yaks suffocate at just 13°C because of this evolutionary flaw

The wild yak is an absolute biological anomaly, engineered by millions of years of natural selection to thrive in the freezing, hypoxic death zone of the Tibetan Plateau. Equipped with oversized organs and permanent fetal blood, this 2,000-pound titan easily survives negative 40 degrees but dangerously overheats at a mild 13°C. As the Roof of the World warms at twice the global rate, its flawless frozen-world adaptations are turning into a lethal trap.
