Your Feces Is a Wonderland of Viruses
sciencehabit writes "Thanks to an anlaysis of fecal samples from four sets of Missouri-born female identical twins and their mothers, researchers have concluded that human guts harbor viruses as unique as the people they inhabit; the viral lineup differs even between identical twins. Even more surprising? These viruses may be doing good work inside of us."
From my understanding of evolution, I think it would be more surprising if something we all have inside of us was doing something bad.
My other sig is clever.
