Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 20 August 2020 doi:10.20944/preprints202008.0453.v1 Abstract Records of domestic dogs in the Americas include specimens from North American sites dating as far back as 10,000 to 8,400 ybp and from the Andes of South America from 5,600-5,000 ybp. Dogs accompanied humans in several migrations from Asia to America BCE, as revealed by different haplotypes reported from ancient DNA studies. Dog acquisition by Amazonian cultures began towards the end of the nineteenth century. Pre-Columbian size and shape diversity in North America is first recorded around 4,000 ybp, with varieties such as the hairless, short nosed and loberro dogs. The humped kind may represent a phenotype associated with mutations in the myostatin gene.
