Yet its origins, usually buried in the deep past, have remained unclear. For example, it is unknown how multicellular traits arise and emerge as repeatable and heritable. It is also unclear how spatial patterns of cell differentiation arise from undifferentiated origins. However, there is a growing understanding that physical considerations play an outstanding role in shaping incipient multicellularity. Here, we use this biophysical viewpoint to investigate how physical constraints arise in freshly multicellular groups, and how these constraints may enable or limit subsequent adaptation and evolution. We show, through a combination of experiments, simulations, and theory, that some properties of multicellularity, that are historically considered difficult to achieve, can freely emerge without needing group-level genes. We suggest that by considering more biophysical challenges for nascent multicellularity, we may yet find solutions to problems that were previously considered unsolvable.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":" Biophysical Constraints of Multicellularity: Building a Darwinian Material"}],"uid":"27707","created_gmt":"2023-02-20 14:55:12","changed_gmt":"2023-02-20 14:55:12","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2023-02-22T13:30:00-05:00","event_time_end":"2023-02-22T15:30:00-05:00","event_time_end_last":"2023-02-22T15:30:00-05:00","gmt_time_start":"2023-02-22 18:30:00","gmt_time_end":"2023-02-22 20:30:00","gmt_time_end_last":"2023-02-22 20:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
