[permaculture] The Heretic - Was Thoughts on PDCs

Permaculture seems to be wrestling with the same growth issues that the rest of society has in the past. It's popularity is waxing due to market forces, but centralized control and homogeneity is counter to its very nature. The analogy of cellular structure comes to mind. A successful cell model doesn't swell into gigantism; it replicates itself at scale, with minor regional variations. Over enough distance two cells might have very little in common.
Of course we can always hope for anagenesis. Or not. Nothing terribly permacultural about it.

Speciation is the evolutionary process by which new biological species
arise. The biologist Orator F. Cook seems to have been the first to coin
the term 'speciation' for the splitting of lineages or 'cladogenesis,'
as opposed to 'anagenesis' or 'phyletic evolution' occurring within
lineages. Whether genetic drift is a minor or major contributor to
speciation is the subject of much ongoing discussion. There are four
geographic modes of speciation in nature, based on the extent to which
speciating populations are geographically isolated from one another:
allopatric, peripatric, parapatric, and sympatric. Speciation may also
be induced artificially, through animal husbandry or laboratory
experiments. Observed examples of each kind of speciation are provided
anagenesis (phyletic evolution)
Anagenesis, also known as "phyletic change," is the evolution of species
involving an entire population rather than a branching event, as in
