Next. Diamond likewise argues that the Eurasian landmass offered a uniquely amenable population of potentially-domesticable proto-livestock. His principal contrast here is to the Americas, where Amerindians puzzlingly domesticated nothing but the llama, the alpaca, the Muscovy duck, and the (yum!) (awwww) (yum!) (awwww) guinea pig (the foregoing being the Andeanist version of the tastes great/less filling debate). Now, again, this argument runs into the a posteriori problem. He asserts that it is possible to infer that undomesticated animals are and always have been undomesticable animals. But this is unpersuasive. It supposes that we moderns (or specifically Jared Diamond) could (for example) look at a jungle fowl and infer, finger lickin’! even in the absence of domesticated chickens. He surveys the world outside Eurasia and declares it deficient in proto-goats, proto-chickens, proto-pigs, proto-cows, proto-sheep… Make of this what you will, in essence it is hand-waving.
Furthermore, in the lowland South American context at least, there is considerable evidence that human-animal relationships are in important respects conceptualized and experienced as relations between social equals, such that a pastoral, dominating, domesticating relationship is rendered “no good to think” (apologies to Stanley Tambiah). Philippe Descola is writing about this, and the work of Eduardo Viveiros de Castro lends itself to the same interpretation. This sounds a bit New Age & woo-woo as I’ve thumbnailed it here, but (I promise) it is compelling and thought-provoking when properly expounded. Given the many parallels between Melanesia and Amazonia, I wonder if a similar analysis would be applicable there (and, perhaps, elsewhere too). The point, though, is that given the presence of potentially useful animals, it is not a foregone conclusion that humans will set about domesticating them. It is simply not valid to read back from a present absence of domesticated animals a past dearth of proto-domestic animals.
