We are not entirely human, germ gene experts argue

`We may not be entirely human, gene experts said on Thursday after studying the DNA of hundreds of different kinds of bacteria in the human gut.

Bacteria are so important to key functions such as digestion and the immune system that we may be truly symbiotic organisms — relying on one another for life itself, the scientists write in Friday’s issue of the journal Science. [..]
