Pre-Columbian chickens, dates, isotopes, and mtDNA
MetadataShow full item record
Recently Gongora et al. ( 1) stated that their analyses of chicken mtDNA and potential offsets for dietary marine carbon cast doubt on "claims for pre-Columbian chickens" in the Americas. We present additional data supporting the interpretation of Storey et al. ( 2) showing that evidence for pre-Columbian chickens at the site of El Arenal, Chile, is secure.
