Actually wheat and barley did start out as marginal so it crops, but this is irrelevant to modern agriculture. The reason we can feed the almost 8 billion people on the planet is that we have selected for strains that respond to fertiliser and agrochemicals. The selective breeding for improvement of kangaroos is not a binary choice - you can improve for multiple traits and balance for multiple requirements. Where in the hell have I even hinted at “brown native people would never figure this out”? This is frankly very offensive.
