[Experimenting with transposing a concept coined in one domain to another domain, perhaps not completely legibly to the entire intended audience.]
In Darwinian Populations and Natural Selection, Peter Godfrey-Smith introduces a bunch of useful concepts allowing us to think more clearly about evolution and its constitutive processes. One of those is the distinction between three types of reproducers: collective, simple, and scaffolded (introduced in chapter 5.1). The short explanation of those categories is as follows.
- Simple reproducers are entities capable of self-sufficient reproduction that are not composed of entities that themselves are self-sufficient reproducers.
- The paradigmatic example is a bacterium. Eukaryotic cells are less paradigmatic examples because it involves mitochondria, which themselves are in-betweenish cases between simple and scaffolded.
- Collective reproducers are entities capable of self-sufficient reproduction that are composed of entities that themselves are self-sufficient reproducers (simple or collective).
- The paradigmatic example is a multicellular organism (insofar as we take the individual eukaryotic cells to be simple reproducers, see the point above).
- Scaffolded reproducers are entities that reproduce only by relying on the reproductive machinery that is not "their own".
- Paradigmatic examples are genes and viruses (central Dawkinsian replicators). Less paradigmatic [...]
