Just warm enough

Mammals' body temperatures may represent balance between warding off fungi and limiting food needs

Fungi may be to thank for mammals’ warm blood, a new theory suggests. But exactly how hot-blooded an animal is may depend on balancing fungal protection with food consumption. 

The optimum body temperature for organisms to ward off fungal infections without burning too much energy is 36.7Ë Celsius — close to the core body temperatures of mammals, including humans, researchers at Albert Einstein College of Medicine in New York City reported online November 9 in mBio. The finding is the late...
