Standards of evidence and Paleoindian demographics.
Buchanan et al. (1) correctly identify accurate Paleoindian population estimates as an important test of the Younger Dryas boundary (YDB) extraterrestrial impact hypothesis (2). They claim that cumulative probabilities of 628 14C-dated components provide evidence for population continuity across the YDB. In fact, only 80 components fall within the interval of interest ( 11,500 to 10,500 14C yea...
متن کاملExperimental Evidence for Beam-beam Disruption at the Slc
A significant luminosity enhancement from beam-beam disruption was observed for the first time during the 199798 run of the SLAC Linear Collider (SLC). Disruption, or pinch effect, is due to the decrease in effective beam size during collisions as each beam is focused by the field of the other beam. With beam intensities of 4.
متن کاملEvidence for a widespread climatic anomaly at around 3 9 . 2 ka before present
7 [1] The 8.2 ka event was triggered by a meltwater pulse (MWP) into the North Atlantic and resultant reduction 8 of the thermohaline circulation (THC). This event was preceded by a series of at least 14 MWPs; their impact on 9 early Holocene climate has remained almost unknown. A set of high-quality paleoclimate records from across 10 the Northern Hemisphere show evidence for a widespread and ...
متن کاملExplaining variability in Early Paleoindian foraging
We have argued elsewhere [Cannon, M.D., Meltzer, D.J., 2004. Early Paleoindian foraging: examining the faunal evidence for large mammal specialization and regional variability in prey choice. Quaternary Science Reviews 23, 1955–1987] that the North American archaeofaunal record provides little support for the notion that Early Paleoindians across the continent practiced a uniform subsistence st...
