>male or female, but that the distinction exists at all and is so widespread. Fair enough. I do find it interesting that even in plants that have N different sexes, their life cycles are still often dimorphic. Maybe the most fundamental abstraction really is the difference between a 1 and a 0.

There is also the third gender in domesticated animals: human breeders. Humans breeders are curating the species and easing the growth of human-favored varieties. There is also the interesting consequences of that in human-disfavored species who evolve to survive in distributed ways despite, or even possibly using our intelligence and tactics in their favor (cockroaches, rodents, viruses, parasites, kudzu, you name it). Nature is a massive calculator, and its algorithms are so interesting, we’ve got to test more of them in computing.

  >There is also the interesting consequences of that in human-disfavored species who evolve to survive in distributed ways despite, or even possibly using our intelligence and tactics in their favor (cockroaches, rodents, viruses, parasites, kudzu, you name it). Nature and nurture. Gattica-level eugenics, at the end of the day, only affect the DNA. And eugenics will never save someone from the adage "Hard times make strong men. Strong men make good times. Good times make weak men. Weak men make hard times."

    Not sure that adage is any true? Eg western militaries don't seem to be worse at fighting than militaries from poor countries?

  Also have a look at rye and oats. They are both thought to be the result of Vavilovian mimicry. > In plant biology, Vavilovian mimicry (also crop mimicry or weed mimicry[1][a]) is a form of mimicry in plants where a weed evolves to share one or more characteristics with a domesticated plant through generations of artificial selection.[2] It is named after Nikolai Vavilov, a prominent Russian plant geneticist.[2] Selection against the weed may occur by killing a young or adult weed, separating its seeds from those of the crop (winnowing), or both. This has been done manually since Neolithic times, and in more recent years by agricultural machinery. > Vavilovian mimicry is a good illustration of unintentional selection by humans. Although the human selective agents might be conscious of their impact on the local weed gene pool, such effects go against the goals of those growing crops. Weeders do not want to select for weeds that are increasingly similar to the cultivated plant, yet the only other option is to let the weeds grow and compete with crops for sunlight and nutrients. Similar situations include antibiotic resistance and, also in agricultural crops, herbicide resistance. Having acquired many desirable qualities by being subjected to similar selective pressures, Vavilovian mimics may eventually be domesticated themselves. Vavilov called these weeds-become-crops secondary crops. From https://en.wikipedia.org/wiki/Vavilovian_mimicry https://en.wikipedia.org/wiki/Vavilovian_mimicry
