A biological precedent for penetrations testing?
Evidence for a biological precedent may be the many retroviruses integrated into the human genome. Presumably, one of these becomes active now and then at random and kills the host cell if the anti-viral defenses of the latter have become weak due to some somatic mutation. The red team-blue team strategy seems to be too good a trick for nature to miss (TGTNM).
Evolution of the trickster
09-27-2020: Modern human populations may have two (independent?) axes of political polarization: oppressor-oppressed and trickster-control freak. The first may sub serve dispersal by generating refugee groups and the second may sub serve building. Any built thing must serve in a complex world in which many constraints must be simultaneously observed. Thus, after the initial build, a long period of tweaking must typically follow. The role of the tricksters is to powerfully motivate this tweaking before the complacency of the control-freak builders leads to disaster. <03-12-2021: This may have been how engineering was done by an archaic version of Homo sapiens.><12-02-2022: The tricksters can also make mistakes, causing damage that cannot have a silver lining in any possible world, and moving to correct this is a natural role of the builders. If you are a builder, ask this: “What is the best use of my indignation?” It is to keep to a strict harm-reduction approach.>
A tangent about our evolutionary context
Our evolutionary forebears may have been champion dispersers for a long time <12-21-2020: i.e., Homo erectus*> before the ice age** forced some of them to become champion builders (initially, of shelters and warm clothing). <12-31-2020: "champion environment modifiers" may be closer to the mark than "champion builders"> It is an interesting fact that physically, humans exceed all other animals only in long-distance running, which can be read as dispersal ability. Our carelessness with preserving the local environments and our propensity for overpopulation can be read as typical r-selected disperser behavior. <12-21-2020: The r-selecting niche was probably big game hunting. H. erectus sites indicate consumption of medium and large meat animals. Overhunting would have occurred routinely, due to the slow reproduction rates of large animals and the high hunting efficiency of H. erectus due to tool use, so that dispersal of the hunters to new habitats would likewise have been routine.>
* H. erectus: lived 2 million years ago to 100,000 years ago. H. sapiens: earliest fossils, 300,000 years old. Evidence of behavioral modernity: 100,000–70,000 y ago.
** that is, the Pleistocene ice age, itself a sequence of 5 successive continental glaciations (by oxygen isotope evidence) separated by temperate periods, starting 2.6 million years ago and thought to be not over yet. Over the past 800,000 y, continental glaciation has happened rhythmically on a 100,000-y cycle due to astronomical factors (Milankovitch cycle). Selection for building skill may therefore have occurred in multiple successive episodes over the course of the Pleistocene.
