Hands up who has ever eaten anything from that list!

Fiddleheads from ferns are available at farmer's markets in the spring in my area, though not from the cinnamon fern specifically.

I'm having trouble finding sources for other specific fern species, though many ferns have been around for hundreds of millions of years.

my wife and I regularly eat lotus root, it's quite delicious and common in chinese cooking. the others not so much.

On a side note there are 1000s even 10s of thousand of edible plant based species that grow on the earth. i don't know how old they are though.

I used to get them at Whole Foods in Nashua, NH. They're quite seasonal so I'd always grab some if I see em.

Seeing my neighbors gathering ginkgo nuts made me curious enough to try them, and I waded right in without understanding the risks! TLDR— they're not a great food source. It's yet another one of those cases where you have to wonder what "delicacy" means. The actual fruit (looks like a rotten plum, smells terrible) has ginkgolic acids which cause contact dermatitis (think poison ivy). Then the nuts themselves contain…

I eat foods with long history of co-evolution and domestication.

Barley and Yogurt, they are the dogs we domesticated from wolves that changed us too.

Daily barley water is a life changer, I don't think our digestive systems really function without a smidgen of daily barley.

This is an interesting way to think about plants and animals. I'm finding it surprisingly hard to find sources for known age of species - is that information collected somewhere? Or is it something we often just don't know because of how sparse the fossil record is? Wondering because of trying to look up the age of fern species I do eat (no cinnamon fern near me) and I can't find out.

It depends on what you mean by the age of the species. You can find the oldest known fossil occurrence at the Paleobiology Database [1] and the divergence time from molecular phylogenies via TimeTree [2].

Fun idea. At least one correction for the table: For wila/bryorii fremonti's age of 250mya they cite the "geologic history" of... moss. Wila is a lichen, which is primarily fungal with algal symbiotes. https://en.wikipedia.org/wiki/Bryoria_fremontii And even given an edible moss, the fact that moss existed 250mya would not imply that particular species existed "morphologically unchanged". The "reindeer lichen" entry appears to have the same issue.
