Human Community

"What are little boys made of? Frogs and snails and puppy-dogs' tails..."

Mitochondria- Wikimedia
Not quite true but substitute bacteria and you are on the right track.   These thoughts were stimulated by an interesting article we came across in the NAMA newsletter*.  Not Just Kingdoms But Communities by Susan Goldhor**  is a thoughtful brief essay on our relationship to the biological world.  I have posted a copy at Google Docs.

It is now generally accepted that the mitochondria in our cells are of bacterial origin, specifically proteobacteria.  Without plunging deeply into the biology, the current endosymbiotic hypothesis suggests that bacteria were taken up by a cell (endocytosis- a common phenomona) and subsequently not only survived but reproduced within the cells as they divided.

That is enough science for now.   I suggest you read Not Just Kingdoms But Communities. Just one page long, it is rich in insights.   Part bacteria, part virus, you may be what your cells ate- billions of years ago.
