Faith versus fact: the problem of Native American creationism and paleoanthropology in North America – Why Evolution Is True
This article in Quillette caught my eye because it was about science—paleoanthropology—and its conflict with faith. The authors are a pair of anthropologists who have written a book about the topic, which is the perennial conflict between scientists on the one hand and Native Americans claiming ancient human remains that, they say, are their ancestors.…

A timeframe for human evolution | Nature Portfolio Ecology & Evolution Community
A precise timeframe for human evolution is fundamental to contextualise key events that occurred during the evolution of our lineage. Our new phylogenetic study dates specific speciation events and provides important insights into body mass and encephalization trends in human evolution.

Genes, Ancient DNA Studies in Pre-Columbian Mesoamerica
Mesoamerica is a historically and culturally defined geographic area comprising current central and south Mexico, Belize, Guatemala, El Salvador, and border regions of Honduras, western Nicaragua, and northwestern Costa Rica. The permanent settling of Mesoamerica was accompanied by the development of agriculture and pottery manufacturing (2500 BCE–150 CE), which led to the rise of several cultures connected by commerce and farming. Hence, Mesoamericans probably carried an invaluable genetic diversity partly lost during the Spanish conquest and the subsequent colonial period. Mesoamerican ancient DNA (aDNA) research has mainly focused on the study of mitochondrial DNA in the Basin of Mexico and the Yucatán Peninsula and its nearby territories, particularly during the Postclassic period (900–1519 CE). Despite limitations associated with the poor preservation of samples in tropical areas, recent methodological improvements pave the way for a deeper analysis of Mesoamerica. Here, we review how aDNA research has helped discern population dynamics patterns in the pre-Columbian Mesoamerican context, how it supports archaeological, linguistic, and anthropological conclusions, and finally, how it offers new working hypotheses.
