The Importance of Keystone Species in the Ecosystem

I think that idea of keystone species is really important. And some of the keystone species are sometimes now called next generation probiotics or next generation organisms. They're your achromosia, take-off bacteria and paltzni.

That tends to be certain things in the prebiotic world,. like resistant starch as an example.
