Boars, Barrows, and Breeders: The Reproductive Status of Domestic Pig Populations in Mainland New Guinea

Mesolithic domestic pigs at Rosenhof – or wild boar? A critical re-appraisal of ancient DNA and geometric morphometrics

“…Some, particularly females, would encounter wild boar and be incorporated into the wild population. Given (a) the long period of co-existence between foragers and farmers, (b) the likelihood that the LBK domestic pigs were managed in a loose pannage system , and (c) the documented extent to which wild and domestic pigs freely interbreed (Albarella, Tagliacozzo et al 2006;Albarella et al 2007;Dwyer 1996), it is not surprising that genetic signatures of these introduced LBK domestic animals crop up among indigenous wild boar solely through introgression between escapes and native animals. Thus metrically and behaviourally wild boar would sometimes have the spotted coat inherited from a domestic ancestor -we see no reason why this trait should always be eliminated in the wild (contra Krause-Kyora et al 2013, 2).…”

Distinguishing Wild Boar from Domestic Pigs in Prehistory: A Review of Approaches and Recent Results

“…To examine whether this suggestion is valid, we can consider Dwyer's (1996) ethnographic study of pig husbandry in New Guinea. In addition to hunting, he defines three forms of human-pig relationship that he terms 'domestication':…”

Pig Domestication Processes: An Analysis of Varieties of Household Pig Reproduction Control in a Hillside Village in Northern Thailand

“…Previous studies have noted the existence of cases of mating between domesticated pigs and wild boars (Nozawa 1986) in the Philippines (Kurosawa et al 1989), and in Laos (Kurosawa et al 2000). Furthermore, in New Guinea, cases of mating between domesticated pigs and wild pigs have been documented (Dwyer 1996). In this study, I have also documented cases of mating between domesticated pigs and wild boars (CMW and UMW), although further research is needed on the frequency of UMW in households whose pigsties were situated in cultivated fields close to the forest outside the village settlement.…”

“…Zeuner 1963;Ingold 1996), and in the case of pigs, notably New Guinea (Galton 1865;Golson and Hughes 1980;Hide 1981Hide , 2003Baldwin 1982;Yen 1991;Dwyer 1996;Dobney and Larson 2006;Sillitoe 2007). It should be noted that the so-called 'wild pigs' in New Guinea are feral descendants of introduced domesticated pigs (Sauer 1952;Larson et al 2007;Dobney et al 2008).…”
