Parsing the relative effects of these factors and understanding interactions among them requires a clear view of the timing and nature of bow use across North America\u2019s diverse geography. This talk explores adoption of the bow in North America from two perspectives. First, I\u2019ll present evidence for the bow\u2019s earliest appearance, use in conjunction with other projectile technologies, and effects on economic and other systems in several North American ecoregions. Second, I'll present a novel model of technological investment (uptake) that considers effects of people\u2019s social roles: Whether people are craft specialists or do-it-yourselfer tool producers\u2013users affects rates of adoption. This hypothesis has global-scale implications, which I\u2019ll demonstrate through regional case studies. I\u2019ll argue that adoption depended not just on the bow's inherent utility but also on how the technology was produced, shared, used, and valued in different economic systems.", "occurrence_notes":null, "guid":"143754-21893746@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/143754", "building_id":"1000221", "building_name":"School of Education", "campus_maps_id":"136", "room":"1322", "location_name":"School of Education", "has_livestream":0, "cost":"", "tags":["Anthropology"], "website":"", "sponsors":[ { "group_name":"Museum of Anthropological Archaeology", "group_id":"3760", "website":"" }, { "group_name":"Department of Anthropology", "group_id":"3469", "website":"https:\/\/lsa.umich.edu\/anthro" }, { "group_name":"Interdepartmental Program in Ancient Mediterranean Art and Archaeology", "group_id":"3719", "website":"" }, { "group_name":"Archaeology at Michigan", "group_id":"5160", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/01\/event_143754_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_thumb\/media\/attachments\/2026\/01\/event_143754_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/01\/event_143754_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/01\/event_143754_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/01\/event_143754_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2026\/01\/event_143754_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2026\/01\/event_143754_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2026\/01\/event_143754_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2026\/01\/event_143754_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2026\/01\/event_143754_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2026\/01\/event_143754_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/01\/event_143754_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/01\/event_143754_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2026\/01\/event_143754_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2026\/01\/event_143754_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/01\/event_143754_original-1.png" }, "occurrence_count":1, "first_occurrence":21893746 } , "95986-21892250": { "datetime_modified":"20260210T142109", "datetime_start":"20260116T120000", "datetime_end":"20260116T124500", "has_end_time":1, "date_start":"2026-01-16", "date_end":"2026-01-16", "time_start":"12:00:00", "time_end":"12:45:00", "time_zone":"America\/Detroit", "event_title":"Expedition Reef", "occurrence_title":"", "combined_title":"Expedition Reef", "event_subtitle":"", "event_type":"Presentation", "event_type_id":"16", "description":"Learn the secrets of the \u201crainforests of the sea\u201d as you embark on an oceanic safari of the world\u2019s most vibrant\u2014and endangered\u2014marine ecosystems.
