Previous studies have shown that species traits, such as physical characteristics or ecological roles, often fail to explain these patterns. This dissertation explores whether emergent, population-level processes influence species formation and extinction rates, thus addressing a core question in evolutionary biology: how and why did life become so diverse? Specifically, I investigate whether sexual selection intensity (Chapter 2) and population-level persistence over decadal timescales (Chapter 3) or millennia (Chapter 4) drive diversification rates at million-year timescales. I also show how mixing different levels of organization, like species and populations, can severely bias inferences on evolutionary rates across millions of years (Chapter 5). Finally, I present an open-source tool for teaching evolutionary biology through an interactive, data-driven framework (Chapter 6). I conclude that a comprehensive understanding of Earth's biodiversity dynamics demands the integration of evidence across a wide array of disciplines.", "occurrence_notes":null, "guid":"146238-21898693@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/146238", "building_id":"1005169", "building_name":"Biological Sciences Building", "campus_maps_id":"631", "room":"1010", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology","Bsbsigns","Graduate Students","Graduate School","eeb","Ecology And Evolutionary Biology","Ecology & Biology","Dissertation"], "website":"", "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Defenses", "group_id":"3821", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/03\/event_146238_original-1.jpg" }, "occurrence_count":1, "first_occurrence":21898693 } , "146709-21899516": { "datetime_modified":"20260317T171335", "datetime_start":"20260311T090000", "datetime_end":"20260311T163000", "has_end_time":1, "date_start":"2026-03-11", "date_end":"2026-03-11", "time_start":"09:00:00", "time_end":"16:30:00", "time_zone":"America\/Detroit", "event_title":"Exhibition: Wayward Images", "occurrence_title":"", "combined_title":"Exhibition: Wayward Images: Angela Chen, Aaron Turner, Ricky Weaver", "event_subtitle":"Angela Chen, Aaron Turner, Ricky Weaver", "event_type":"Exhibition", "event_type_id":"7", "description":"March 9-April 3, 2026\n--\nThe public is cordially invited to an artist's reception on Wednesday, March 27th at 4:30 pm in the RC Art Gallery.\n--\n\nPublic Workshop: On March 19th from 1 to 3pm, join exhibiting artist Stamps School of Art & Design Assistant Professor Angela Chen for a collaborative bookmaking workshop! Drawing on the themes from her latest book and exhibition After School \u8ab2\u5f8c, participants are invited to critique educational systems by cutting up old textbooks and creating new photocopy collages. All materials will be provided, but participants are welcome to bring their own texts to deconstruct!\n\n--\nAngela Chen - Artist Statement: Angela Chen\u2019s After School brings together collage, sculpture, and new and historical photographs to unpack the culture of after school tutoring centers in California. Known as \u88dc\u7fd2\u73ed (buxiban) in Chinese, after schools are referred to colloquially as \u201ccram schools\u201d and by scholars as \u201cshadow education.\u201d Operating simultaneously as spaces of community, care, and control, these schools can be demanding and factory-like; but they also deliver essential childcare services to busy parents, many of whom are new immigrants. As a child and young adult, Chen attended and worked at Futurelink School, a buxiban and her parents\u2019 business. Located in the San Gabriel Valley, CA, Futurelink served hundreds of primarily East Asian students, providing them with homework help and supplemental English and math lessons. Inspired by Futurelink\u2019s vast archive of photographs, workbooks, objects, and advertisements, After School explores the role of education in Asian American enclaves and challenges stereotypes about Asian American students. Assemblages combine Futurelink photographs with photographs of California Chinese schools during the Chinese Exclusion era to reflect on the ongoing legacies of racism, segregation, and US immigration policy within the Asian American experience.\n\nAaron Turner - Artist Statement: Aaron Turner\u2019s Black Alchemy (2014 - Present) speaks to the broad spectrum of identity and speculative aesthetics, drawing from lived experience, archives, American history, and art history. He uses the light in combination with the Darkroom, alternative and 19th-century printing processes, the view camera (4x5 & 8x10), geometric abstraction, assemblage, and monochromatic pictorial experimentation to respond to internal questions about representation, the discursive enterprise, and the artists' role in the studio space.\nBlack Alchemy provides a lens through which he sees the world while simultaneously considering the past, present, and future, translating knowledge and perspective outside the intellectual studio space.\n\nRicky Weaver - Artist Statement: Ricky Weaver\u2019s work co-conspires with the poetics and temporality of Black feminist metaphysics embeded in the Black Quotidian. These images locate a code that can be traced back to the Middle Passage\u2014one that disrupts the paradigmatic ways of archiving Blackness and outsmarts surveillance technologies as such. Her application of scripture, hymn, and colloquial passages come together in acts of dark sousveillance to recall language that implies worlds that don\u2019t require an escape. She addresses the sonic, linguistic, and visual as a way to posture the body as a central apparatus for storing, downloading, and transferring archives.", "occurrence_notes":"All welcome!
