Less Fungus among Us Warm-Blooded

Some people eat to avoid being bored. Others to avoid doing something they’d rather not, like preparing a podcast. Now a report says we might eat to avoid fungi. Because warm-bloodedness, a condition that requires a lot of calories, may have evolved to keep fungal infections at bay.

There are obvious benefits to being warm blooded. Like not having to sit in the sun for a few hours just to get going in the morning. Another, less obvious plus, is the fact that we tend not to get attacked by fungi. Of the one-and-a-half million fungal species on Earth, only a few hundred are capable of infecting mammals. Compare that to a quarter of a million fungi that target plants, and 50,000 species that infect insects. So what makes us mammals relatively fungus-free? It seems to be our hot bodies.
