  1. “Fertile Crescent crop progenitors” paper. This is the wrong paradigm. They consider “role of competition in species mixtures” and “promote the persistence of these species in areas of human settlement, or in early cultivated plots”, that is, in “anthropogenic environments”. This follows Hawkes (1969, “The ecological background of crop domestication”) which is explicit: crop ancestors were ‘ecological weeds’ with large food reserves to resist drying out and which ‘naturally colonized the bare ground and rubbish heaps provided by man.’ No they didn’t.
    Our new paradigm is that domestication has nothing to do with anthropogenic environments in the choice of what to domesticate (doi:10.1098/rspb.2018.0277). The large seed of cereal progenitors was an ecological adaptation to counter seasonal natural disturbance: flooding and most probably fire, going back millions of years. Each year, in the nine months between annual growth, the seed was naturally protected by burying mechanisms at depths where seeds needed to be large to reach light. Of course, large seed allowed monodominance as species without seed-burying had been destroyed. (Janzen’s 1974 vision was that large-seeded monodominant tropical trees needed toxic seeds to prevent being eaten: doi: 10.2307/2989823).
    With the ability to gather large, palatable seed from natural monodominant vegetation the earliest farmers then increased food supplies by closely mimicking Nature (at great trouble) by the need to plough, harrow, and deep seed, as we still do for our annual cereals (and then added crop introduction as a means of escaping co-evolved biotic constraints). All of which shows that monoculture crops are a reasonably exact copy of Nature and, as the UN Food Summit requires, they form, as closely as could be wished, “nature-positive production systems”.
    The many foolish people decrying monocultures have zero understanding of the ecological genius of our earliest farmers.
