This ecological term—which can also be applied to our gut microbiome—refers to the idea that many species can perform the same ecological role.

What is functional redundancy?

The relationship between humans and their gut microbiome may be defined by this symbiotic relationship.

What is a mutualism?

500

The idea that a hard-shelled mollusk is more likely than a soft-bodied leaf to be fossilized refers to this kind of bias.

What is preservation bias?
