Response to Comment by Goldberg et al. on DNA from Pre-Clovis Human Coprolites in Oregon, North America

Goldberg et al. use data from micromorphological and Fourier transform infrared analyses to argue that Paisley Cave pre-Clovis coprolite 1374-5/5D-31-2 is of herbivore, rather than human, origin. We argue that the diagnostic capability of the techniques used by Goldberg et al. are limited, and we present new genetic data that support our original claims.
