Genomic analysis of ancient chum salmon bones and cultural knowledge from the Tsleil-Waututh Nation suggest that people in the Pacific Northwest managed fisheries for thousands of years by harvesting males and releasing females.
The field of ancient DNA, which combines archaeology and anthropology with cutting-edge genetics, is requiring scientists to have frank conversations about when research is justified and who it benefits.
Researchers found the relatively high proportion of DNA from a hominin cousin—nearly 5 percent—when they scanned more than 1,000 genomes from 118 distinct ethnic groups.
Phylogenomics data place the enigmatic plankton in the middle of the algal family tree, despite their apparent lack of plastids—an organelle characteristic of all other algae.
