Study Sheds New Light on Ice Age Mediterranean Settlers

Early human settlers migrated to Sicily during the last Ice Age.
Study Sheds New Light on Ice Age Mediterranean Settlers
The analysis of human skeletal remains found in the Grotta d'Oriente Cave on the island of Favignana, Italy, show that modern humans first settled in Sicily from mainland Italy during the last Ice Age, and that, although they were island dwellers, consumed little seafood, subsisting mostly on terrestrial food sources.
The study, led by Marcello Mannino of the Max Planck Institute for Evolutionary Anthropology, revealed results from a combination of tests and analyses using mitochondrial DNA data, AMS radiocarbon dating, and isotopic analysis on skeletal finds and associated remains of human skeletons, particularly that of skeletal specimen 'Oriente B', unearthed in the cave during archaeological campaigns in 1972 and 2005.
The analysis revealed the time when humans reached the islands of Favignana and Levanzo near western Sicily. These islands were connected to mainland Sicily until the first few millennia of the Holocene Epoch, a geological epoch which began around 12,000 radiocarbon years ago, when seal levels were low as a result of the Glacial Maxima of the last Ice Age. Said Mannino, "The definitive peopling of Sicily by modern humans only occurred at the peak of the last Ice Age, around 19,000 -26,500 years ago, when sea levels were low enough to expose a land bridge between the island and the Italian peninsula". Dating and morphological examination of the skeletal remains confirmed that the early settlers were modern humans.
The study results also showed that these settlers were not fishermen, despite their island environment. They subsisted on terrestrial animals rather than marine sources for meat. Moreover, according to their analysis, this hunter-gatherer lifestyle likely persisted even as sea levels rose during the time of their occupation of the island environment. The authors conclude, based on the evidence from the excavations and the most recent study, that "the limited development of technologies for intensively exploiting marine resources was probably a consequence both of Mediterranean oligotrophy [a water constitution poor in plant nutrient minerals and organisms and rich in oxygen] and of the small effective population size of these increasingly isolated human groups, which made innovation less likely and prevented transmission of fitness-enhancing adaptations".[1]
The research is published November 28 in the open access journal PLOS ONE by Marcello Mannino of the Max Planck Institute for Evolutionary Anthropology, Germany, and colleagues from other institutions.

Skeletons in Cave Reveal Mediterranean Secrets
Nov. 28, 2012 — Skeletal remains in an island cave in Favignana, Italy, reveal that modern humans first settled in Sicily around the time of the last ice age and despite living on Mediterranean islands, ate little seafood. The research is published November 28 in the open access journal PLOS ONE by Marcello Mannino and colleagues from the Max Planck Institute for Evolutionary Anthropology, Germany.
Genetic analysis of the bones discovered in caves on the Egadi islands provides some of the first mitochondrial DNA data available for early humans from the Mediterranean region, a crucial piece of evidence in ancestry analysis. This analysis reveals the time when modern humans reached these islands. Mannino says, "The definitive peopling of Sicily by modern humans only occurred at the peak of the last ice age, around 19,000 -26,500 years ago, when sea levels were low enough to expose a land bridge between the island and the Italian peninsula."
The authors also analyzed the chemical composition of the human remains and found that these early settlers retained their hunter-gatherer lifestyles, relying on terrestrial animals rather than marine sources for meat. According to the study, despite living on islands during a time when sea level rise was rapid enough to change within a single human lifetime, these early settlers appear to have made little use of the marine resources available to them. The authors conclude, "These findings have crucial implications for studies of the role of seafood in the diet of Mediterranean hunter-gatherers."
