Significant Interference

AbstractThe dating of the Campanian Ignimbrite (CI) eruption to ∼37,000 cal yr B.P. draws attention to the coincidence of this volcanic catastrophe and the suite of coeval, Late Pleistocene biocultural changes that occurred within and outside the Mediterranean region. These included the Middle to Upper Paleolithic cultural transition and the supposed change from Neanderthal to “modern” Homo sapiens anatomy, a subject of sustained debate. No less than 150 km3 of magma were extruded in the CI eruption, the signal of which can be detected in Greenland ice cores. As widespread discontinuities in archaeological sequences are observed at or following the CI event, a significant interference with ongoing human processes in Mediterranean Europe is hypothesized.

Imperial Eagle

The use of personal ornaments by Neandertals is one of the scarce evidence of their symbolic behaviour. Among them stand up the eagle talons used presumably as pendants, in an analogous way than anatomically Modern Humans (Homo sapiens) did. Considering the broad range and time scale of Neandertals distribution across Eurasia, this phenomenon seems to be concentrated in a very specific area of Southwestern-Mediterranean Europe during a span of ca. 80 ka. Here we present the analysis of one pedal phalange of a large eagle recovered in Foradada cave site, Spain. Our research confirms the use of eagle talons as symbolic elements in Iberia, expanding geographically and temporally one of the most common evidence of symbolic behaviour among western European Neandertals. The convergence in use of large raptor talons as symbolic elements by one of the last Neandertal populations raises the survival of some cultural elements of the Middle Paleolithic into beginnings of the Upper Paleolithic.

Kenya National Museums Lukenya Hill Hominid 1 (KNM-LH 1) is a Homo sapiens partial calvaria from site GvJm-22 at Lukenya Hill, Kenya, associated with Later Stone Age (LSA) archaeological deposits. KNM-LH 1 is securely dated to the Late Pleistocene, and samples a time and region important for understanding the origins of modern human diversity. A revised chronology based on 26 accelerator mass spectrometry radiocarbon dates on ostrich eggshells indicates an age range of 23,576–22,887 y B.P. for KNM-LH 1, confirming prior attribution to the Last Glacial Maximum. Additional dates extend the maximum age for archaeological deposits at GvJm-22 to >46,000 y B.P. (>46 kya). These dates are consistent with new analyses identifying both Middle Stone Age and LSA lithic technologies at the site, making GvJm-22 a rare eastern African record of major human behavioral shifts during the Late Pleistocene. Comparative morphometric analyses of the KNM-LH 1 cranium document the temporal and spatial complexity of early modern human morphological variability. Features of cranial shape distinguish KNM-LH 1 and other Middle and Late Pleistocene African fossils from crania of recent Africans and samples from Holocene LSA and European Upper Paleolithic sites.

Okmok Volcano

The assassination of Julius Caesar in 44 BCE triggered a power struggle that ultimately ended the Roman Republic and, eventually, the Ptolemaic Kingdom, leading to the rise of the Roman Empire. Climate proxies and written documents indicate that this struggle occurred during a period of unusually inclement weather, famine, and disease in the Mediterranean region; historians have previously speculated that a large volcanic eruption of unknown origin was the most likely cause. Here we show using well-dated volcanic fallout records in six Arctic ice cores that one of the largest volcanic eruptions of the past 2,500 y occurred in early 43 BCE, with distinct geochemistry of tephra deposited during the event identifying the Okmok volcano in Alaska as the source. Climate proxy records show that 43 and 42 BCE were among the coldest years of recent millennia in the Northern Hemisphere at the start of one of the coldest decades. Earth system modeling suggests that radiative forcing from this massive, high-latitude eruption led to pronounced changes in hydroclimate, including seasonal temperatures in specific Mediterranean regions as much as 7 °C below normal during the 2 y period following the eruption and unusually wet conditions. While it is difficult to establish direct causal linkages to thinly documented historical events, the wet and very cold conditions from this massive eruption on the opposite side of Earth probably resulted in crop failures, famine, and disease, exacerbating social unrest and contributing to political realignments throughout the Mediterranean region at this critical juncture of Western civilization.

ABSTRACT Pleistocene human remains are rare inland on the Iberian Peninsula. Most are considered Neandertals, but anthropological analyses and direct dating are rare. Recently, we published a study of a navicular from this region found in the Torrejones Cave. The results showed it differed from that of Neandertals and it was re-identified as Homo sapiens. Following the previous stratigraphic and biochronologic descriptions, we suggested that it could correspond to an Upper Paleolithic human, since the navicular was apparently recovered in the Late Pleistocene from an in situ unit. Direct radiocarbon dating from this fossil (4855–5036 cal BP), believed to be the only Paleolithic Homo sapiens from inland Iberia, as well as other hominin and faunal remains from the site, show that the human bones actually date to the Chalcolithic. The unexpectedly recent chronology for the navicular implies that there is no evidence of human fossils from the Upper Paleolithic in Torrejones Cave. Thus, any date from the Middle/Upper Paleolithic human record should be taken with caution until in-depth paleoanthropological, stratigraphical and/or direct dating studies are conducted. Extraordinary caution is recommended when human remains are recovered from apparently Paleolithic units in contexts bearing Holocene sepulchral units on the uppermost levels and/or some evidence of bioturbation.

Surprising Discovery

This chapter analyzes the transition of the hominins from the Middle Pleistocene to the Late Pleistocene. Two alternative models are explored, the “Multiregional Hypothesis” (MH) and the “Replacement Hypothesis,” and how each model evaluates the existing relationships between the taxa Homo neanderthalensis and Homo sapiens. Next is the investigation of the transitional (or “archaic,” if this grade is taken into account) exemplars found in Europe, Africa, and Asia and their evolutionary significance. In particular, the comparison between H. erectus and H. sapiens in China and Java is investigated, as the main foundation of the MH. The chapter ends with the surprising discovery of Homo floresiensis and its description and interpretations concerning its taxonomic and phylogenetic significance. The correlation between brain development and technological progress is at odds with the attribution of perforators, microblades, and fishing hooks to a hominin with a small cranial volume, similar to that of Australopithecus afarensis.
