- Lisboa Pré-Histórica: uma síntese da informação conhecida em 2020Publication . Sousa, Ana Catarina; Costeira, Catarina; Costa, Ana Maria; Calker, Daniel Van; Cardoso, João Luis; Casimiro, Tânia Manuel; Boavida, Carlos; Carvalho, AntónioEste artigo resultou da fusão de duas comunicações distintas apresentadas na segunda sessão do ciclo de conferências Lisboa não é só Subterrânea — 25 anos depois de uma exposição, ocorrida no dia 4 de maio de 2019: «Depois de 1993: o que mudou na Pré-História de Lisboa», da autoria de um dos signatários (J. L. C.), e «Unir os pontos: uma abordagem geoespacial dos vestígios neolíticos e calcolíticos na cidade de Lisboa», da autoria dos restantes signatários.
- The curious case of the Mesolithic Iberian dogs: An archaeogenetic studyPublication . Pires, Ana Elisabete; Detry, Cleia; Chikhi, Lounes; Rasteiro, Rita; Amorim, Isabel R.; Simoes, Fernanda; Matos, Jose; Petrucci-Fonseca, Francisco; Ollivier, Morgane; Hanni, Catherine; Cardoso, João CR; Arias, Pablo; Diniz, Mariana; Araujo, Ana Cristina; Bicho, Nuno Gonçalo Viana Pereira Ferreira; Sousa, Ana Catarina; Moreno-Garcia, Marta; Arruda, Ana Margarida; Fernandez-Rodriguez, Carlos; Porfirio, Eduardo; Arnaud, Jose Morais; Valente, Alexandra; Goncalves, David; Alves, Lara; Gotherstrom, Anders; Davis, Simon J. M.; Ginja, CatarinaWe investigated the genetic composition of six Canis remains from western Iberia, directly radiocarbon dated to 7,903-7,570 years (cal BP). They were identified as dogs via their archaeological and depositional context, osteometry, and a high percentage of aquatic diet shared with humans. For comparison, genetic data were obtained from an additional 37 Iberian dog remains from the Neolithic to Late Antiquity, as well as two Palaeolithic and a Chalcolithic Canis identified as wolves. Previous data indicated that dog mtDNA haplogroup A (HgA) is prevalent in extant European dogs ( > 50%), in the Near East and Asia, but rare or absent ( < 10%) in European Canis older than 3,000 years (cal BP). We found a high frequency (83%) of dog HgA in Mesolithic Iberian dog remains. This is the first report of a high frequency of dog HgA in pre-Neolithic Europe. We show that, contrary to the current view, Canis with HgA did not necessarily arrive in Europe from East-Asia. This phylogeographical difference in HgA frequency demonstrates that genetic differentiation was high prior to, or as a consequence of, domestication which may be linked with pre-Neolithic local processes for Iberian wolf domestication. Our results emphasize that knowledge of both ancient wolves' and early dogs' genetic profiles from the European periphery should improve our understanding of the evolution of the European dog.
