Ciclo de Conferências Territórios de Fronteira
Irá decorrer às 18 horas do próximo dia 12 de Abril de 2012 novo ciclo Territórios de Fronteira co-organizado pelo Grupo de Estudos em Evolução Humana (GEEVH), pelo Museu Nacional de Arqueologia (MNA) e pelo Núcleo de Arqueologia e Paleoecologia da Universidade do Algarve (NAP).
O ciclo inclui palestras de:
- Cláudia Costa (UNIARQ, Universidade do Algarve) "Companheiros na vida e na morte: a integração de restos de animais nos rituais funerários"
- David Gonçalves (CENCIFOR, IGESPAR, CIAS) "A análise de ossos queimados em contextos arqueológicos: algumas inovações"
- Cristina Cruz (Departamento de Ciências da Vida da Universidade de Coimbra, CIAS) “Viver a morte em Portugal: o potencial informativo dos relatórios antropológicos de campo”
Serão fornecidos certificados de presença.
Contamos com a vossa presença e divulgação!
Obrigada

Evidence suggests Neanderthals took to boats before modern humans

| The Reconstruction of the Funeral of Homo neanderthalensis. Captured in the Hannover Zoo. (Via Wikipedia) |
(PhysOrg.com) Neanderthals, considered either a sub-species of modern humans or a separate species altogether, lived from approximately 300,000 years ago to somewhere near 24,000 years ago, when they inexplicably disappeared, leaving behind traces of their DNA in some Middle Eastern people and artifacts strewn all across the southern part of Europe and extending into western Asia. Some of those artifacts, stone tools that are uniquely associated with them, have been found on islands in the Mediterranean Sea, suggesting, according to a paper published in the Journal of Archaeological Science, by George Ferentinos and colleagues, that Neanderthals had figured out how to travel by boat. And if they did, it appears they did so before modern humans.

Abstract
Climatic forcing during the Younger Dryas (∼12.9–11.5 ky B.P.) event has become the theoretical basis to explain the origins of agricultural lifestyles in the Levant by suggesting a failure of foraging societies to adjust. This explanation however, does not fit the scarcity of data for predomestication cultivation in the Natufian Period. The resilience of Younger Dryas foragers is better illustrated by a concept of adaptive cycles within a theory of adaptive change (resilience theory). Such cycles consist of four phases: release/collapse (Ω); reorganization (α), when the system restructures itself after a catastrophic stimulus through innovation and social memory—a period of greater resilience and less vulnerability; exploitation (r); and conservation (K), representing an increasingly rigid system that loses flexibility to change. The Kebarans and Late Natufians had similar responses to cold and dry conditions vs. Early Natufians and the Pre-Pottery Neolithic A responses to warm and wet climates. Kebarans and Late Natufians (α-phase) shifted to a broader-based diet and increased their mobility. Early Natufian and Pre-Pottery Neolithic A populations (r- and K-phases) had a growing investment in more narrowly focused, high-yield plant resources, but they maintained the broad range of hunted animals because of increased sedentism. These human adaptive cycles interlocked with plant and animal cycles. Forest and grassland vegetation responded to late Pleistocene and early Holocene climatic fluctuations, but prey animal cycles reflected the impact of human hunting pressure. The combination of these three adaptive cycles results in a model of human adaptation, showing potential for great sustainability of Levantine foraging systems even under adverse climatic conditions.
