Lithic analysis in African archaeology: Advances and key themes
Archaeometry, EarlyView.Abstract Stone artifacts (lithics) preserve for extended periods; thus they are key evidence for probing the evolution of human technological behaviors. Africa boasts the oldest record of stone artifacts, spanning 3.3 Ma, rare instances of ethnographic stone tool‐making, and stone tool archives from diverse ecological settings, making it an anchor for ...

L’exploitation des cétacés au Paléolithique récent
Les Nouvelles de l’Archéologie, 2019 The archeology of the foreshore in the Late Paleolithic is difficult to approach, because most of the current seashore lines are far removed from the position they had at that times.

Constant factor approximations for Lower and Upper bounded Clusterings [PDF]
arXiv, 2022 Clustering is one of the most fundamental problem in Machine Learning. Researchers in the field often require a lower bound on the size of the clusters to maintain anonymity and upper bound for the ease of analysis. Specifying an optimal cluster size is a problem often faced by scientists. In this paper, we present a framework to obtain constant factor

Potential Adaptive Introgression From Dogs in Iberian Grey Wolves (Canis lupus)
Molecular Ecology, EarlyView.ABSTRACT Invading species along with increased anthropogenization may lead to hybridization events between wild species and closely related domesticates. As a consequence, wild species may carry introgressed alleles from domestic species, which is generally assumed to yield adverse effects in wild populations.

Contextual Focus: A Cognitive Explanation for the Cultural Revolution of the Middle/Upper Paleolithic [PDF]
In R. Alterman & D. Hirsch (Eds.), Proceedings of the 25th Annual
Meeting of the Cognitive Science Society (pp. 432-437). Austin, TX: Cognitive
Science Society. (2003), 2013 Many elements of culture made their first appearance in the Upper Paleolithic. Previous hypotheses put forth to explain this unprecedented burst of creativity are found wanting. Examination of the psychological basis of creativity leads to the suggestion that it resulted from the onset of contextual focus: the capacity to focus or defocus attention in ...

Topics in Cognitive Science, EarlyView.Abstract Many core human activities require an understanding of time. To coordinate rituals, plan harvests and hunts, recall histories, keep appointments, and follow recipes, we need to grapple with invisible temporal structures like durations, sequences, and cycles. No other species seems to do this.

Dating of two Paleolithic human fossil bones from Romania by accelerator mass spectrometry [PDF]
arXiv, 2003 In this study we have dated two human fossil remains found in Romania, by the method of radiocarbon using the technique of the accelerator mass spectrometry. The human fossil remains from Woman's cave, Baia deFier, have been dated to the age 30150 $\pm$ 800 years BP, and the skull from the Cioclovina cave has been dated to the age 29000 $\pm$ 700 years
