This article says it was for raw vegetables:

For our ancestors, the appendix most likely evolved to help them digest a diet rich in raw vegetables and cellulose, as it still does in many herbivorous mammals. Thousands of years ago it would have functioned as an extension of the cecum, involved in the bacterial digestion of fibrous plant materials.

That is not proven though, the appendix part, that's the explanation I like the best as well. Other explanations, I forget, the aliens had it for some shit we don't even know about, oh yeah, the more likely non joke one, and it could be what you say and this both many organs do multiple things, is to provide a reservoir of gut bacteria, to repopulate the gut after the system is flushed. That would go right along with digesting raw meat, as using independent bacteria is large part of the human body we've come to learn.

I forget what the other theories are, but there are others for the appendix, I believe the raw meat and reservoir of bacteria both though is most likely.

They are still omnivores who choose to limit their diet. Acknowledging that is a choice gives it meaning, which would be lost if it was treated as something similar to being an herbivore.

I am not personally a vegan or vegetarian, but respect the choice to limit one's diet for the purpose of limiting animal suffering.

I've found the rare rational person on this thread. Run before it taints your soul!

Today, most people are "more vegan" than meat eater, too, as in they eat more grains and vegetables than meat. If that's what you meant.

More vegan.

What a curious phrase. Not just for the substitution of vegetarian for vegan, but for the use of "more". More vegan. I thought it was binary. Are there partial vegans? I thought that wasn't allowed.

Because my diet includes more calories and nutrition from plant matter than meat most days, am I more vegan now?
