According to the New York Times it turns out that skin is a very diverse ecosystem!
Dr. Segre, of the National Human Genome Research Insitute, and her team reveal in a paper in Science, it’s really an assortment of mini-ecosystems, with the bacterial diversity varying depending on location. They found, for example, that the most diverse spot, the middle forearm, has more than twice as many species than the least diverse patch, behind the ear.
I’d never thought of it like that and always taken my skin for granted. Any other skin facts welcomed right here!
