Cultural transmission and diversity in time-averaged assemblages
(Current Anthropology, 2014)
Anthropologists have adopted methods from population genetics to study modes of cultural transmission in time-transgressive cultural data sets. However, it remains unclear to what extent methods originally developed to ...
Hitchhiker's guide to genetic diversity in socially structured populations
(Current Zoology, 2012)
When selection increases the frequency of a beneficial gene substitution it can also increase the frequencies of linked neutral alleles through a process called genetic hitchhiking. A model built to investigate reduced ...
What serves as evidence for the presence (or absence) of Pleistocene language?
(Journal of Anthropological Sciences, 2013)
Benítez-Burraco & Barceló-Coblijn present some good reasons for showing caution before interpreting evidence for the introgression of DNA from “archaic” human populations, such as Neandertals and Denisovans, into anatomically ...
Modeling Effects of Local Extinctions on Culture Change and Diversity in the Paleolithic
(Public Library of Science, 2010)
The persistence of early stone tool technologies has puzzled archaeologists for decades. Cognitively based explanations, which presume either lack of ability to innovate or extreme conformism, do not account for the totality ...
The spatial scale of social learning affects cultural diversity
(American Antiquity, 2011)
Sewall Wright’s (1943) concept of isolation by distance is as germane to cultural transmission as genetic transmission. Yet there has been little research on how the spatial scale of social learning— the geographic extent ...
