I, Roving Fermentation Vat

Anyone suffering from a serious case of hubris should take a look at a phylogenetic tree sometime. Kinda puts your big life problems into perspective. You’ll notice most of the tree are bacteria and archaea, and even among the eucaryota, animals are squished somewhere between slime molds and fungi. Oh but even then, most of these animals are insects. Humans, but one branch of the primates, are pretty small beans if you’re looking at this from an overall diversity perspective.

And I don’t have to remind you that in your own body, only about 10 percent of the cells are even human at all. So not only are you small and fairly insignificant in the grand scheme of things, there’s actually no You in the first place.

Aaaaaand cue the Galaxy Song, just to make our point.

They control your tissue growth and development, digest most of your Happy Meal, and determine if you’re going to succumb to that virus you just breathed in from Annoying Close-Talking Coworker. You are their bitch. So chill out and start enjoying the ride.

Here’s a primer by Noah Fierer:
