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 modern humans (AMH) as evidence for the presence of language in the former. The reasons that I found most cogent are that (1) as we continue to learn more about AMH-specific substitutions we may find important differences in the regions of the genome that affect language, such as those recently reported for a regulatory element of the FOXP2 gene (Maricic et al., 2013), and (2) that differences between AMH and archaic humans in endocranial developmental trajectories (Gunz et al., 2012) may have affected the “linguistic phenotype” even if all of the populations shared the same underlying “linguistic genotype.”
