The University of Alabama Press, Tuscaloosa. 508 pp.	2018	3	.pdf	application/pdf	1583	84	43	Diverse interactions between humans involve adaptation to the environment and over time, human groups are interwoven with others in increasingly complex interactions that imply acceptance or rejection of artifacts, ideas, and technologies in unpredictable ways, which set diverse cultural trajectories (Bentley and Maschner 2007). On the other, he points out the problems to evaluate the existence or the extent of contacts between human groups of both hemispheres, which is due to lack of a characterization of what objects and practices are diagnostic to identify these exchanges and the implications of those exchanges to understand cultural evolution.	cache/ebl-1352.pdf	txt/ebl-1352.txt
