The Family

Fifteen species of insect herbivores were discovered on ferns growing along the Pacific northwest coast of North America. These included insects from the orders: Diptera in the families Anthomyiidae, Cecidiomyiidae and Syrphidae: Lepidoptera in the families Erebidae, Tortricidae and Noctuidae: Hymenoptera in the family Tenthredinidae: Hemiptera in the family Aphididae and Coleoptera in the family Curculionidae.  The present study illustrates these associations that provides new world and North American host records of fern herbivores. The fossil record of these families is used to determine if the most ancient of these insects (dating from the Mesozoic) are now mostly restricted to ferns and the most recent ones (dating from the Cenozoic) are mostly polyphagous, feeding on ferns as well as various angiosperms.  Results indicate that the insect clades belonging to the most ancient families, such as Aneugmenuss and Strongylogaster in the Tenthredinidae and Dasineura and Mycodiplosis in the Cecidiomyiidae, appear to be monophagous on ferns.

Recent genomic studies of both ancient and modern indigenous people of the Americas have shed light on the demographic processes involved during the first peopling. The Pacific Northwest Coast proves an intriguing focus for these studies because of its association with coastal migration models and genetic ancestral patterns that are difficult to reconcile with modern DNA alone. Here, we report the low-coverage genome sequence of an ancient individual known as “Shuká Káa” (“Man Ahead of Us”) recovered from the On Your Knees Cave (OYKC) in southeastern Alaska (archaeological site 49-PET-408). The human remains date to ∼10,300 calendar (cal) y B.P. We also analyze low-coverage genomes of three more recent individuals from the nearby coast of British Columbia dating from ∼6,075 to 1,750 cal y B.P. From the resulting time series of genetic data, we show that the Pacific Northwest Coast exhibits genetic continuity for at least the past 10,300 cal y B.P. We also infer that population structure existed in the late Pleistocene of North America with Shuká Káa on a different ancestral line compared with other North American individuals from the late Pleistocene or early Holocene (i.e., Anzick-1 and Kennewick Man). Despite regional shifts in mtDNA haplogroups, we conclude from individuals sampled through time that people of the northern Northwest Coast belong to an early genetic lineage that may stem from a late Pleistocene coastal migration into the Americas.

AbstractRecent genome-wide studies of both ancient and modern indigenous people of the Americas have shed light on the demographic processes involved during the first peopling. The Pacific northwest coast proves an intriguing focus for these studies due to its association with coastal migration models and genetic ancestral patterns that are difficult to reconcile with modern DNA alone. Here we report the genome-wide sequence of an ancient individual known as “Shuká Káa” (“Man Ahead of Us”) recovered from the On Your Knees Cave (OYKC) in southeastern Alaska (archaeological site 49-PET-408). The human remains date to approximately 10,300 cal years before present (BP). We also analyze low coverage genomes of three more recent individuals from the nearby coast of British Columbia dating from approximately 6075 to 1750 cal years BP. From the resulting time series of genetic data, we show that the Pacific Northwest Coast exhibits genetic continuity for at least the past 10,300 cal BP. We also infer that population structure existed in the late Pleistocene of North America with Shuká Káa on a different ancestral line compared to other North American individuals (i.e., Anzick-1 and Kennewick Man) from the late Pleistocene or early Holocene. Despite regional shifts in mitochondrial DNA haplogroups we conclude from individuals sampled through time that people of the northern Northwest Coast belong to an early genetic lineage that may stem from a late Pleistocene coastal migration into the Americas.Significance StatementThe peopling of the Americas has been examined on the continental level with the aid of single-nucleotide polymorphism arrays, next generation sequencing, and advancements in ancient DNA, all of which have helped elucidate major population movements. Regional paleogenomic studies, however, have received less attention and may reveal a more nuanced demographic history. Here we present genomewide sequences of individuals from the northern Northwest Coast covering a time span of ~10,000 years and show that continental patterns of demography do not necessarily apply on the regional level. In comparison with existing paleogenomic data, we demonstrate that geographically linked population samples from the Northwest Coast exhibit an early ancestral lineage and find that population structure existed among Native North American groups as early as the late Pleistocene.

Summary This article reconsiders various aspects of missionary linguistics on the Pacific Northwest Coast in the late 19th century. In particular, it explores the complex relationship between Alfred Hall’s (1853–1918) A Grammar of the Kwagiutl Language (1888) and Charles Harrison’s (d.1926) Haida Grammar (1895), and it is shown that, in many cases, both the basic analytical framework and the clarificatory examples that Harrison used were largely derived from Hall’s work. Such connections have not been recognised previously, and yet they are of importance, since they indicate that traditional Graeco-Roman categories and paradigms were not the only templates used by missionaries who were seeking to analyse the indigenous languages of North America. In addition, Hall’s and Harrison’s accounts of numerals in Kwak’wala and Haida (respectively) are reassessed, and it is suggested that their analyses were influenced by the classificatory approaches presented in contemporaneous studies of non-Western languages (e.g., Japanese).
