The most well-known pattern associated with adaptive radiation is an early burst of phenotypic diversification. Venoms facilitate prey capture and are widely believed to be key innovations leading to adaptive radiation. However, few studies have estimated their evolutionary rate dynamics. Here, we test for patterns of adaptive evolution in venom gene expression data from 52 venomous snake species. By identifying shifts in tempo and mode of evolution along with models of phenotypic evolution, we show that snake venom exhibits the macroevolutionary dynamics expected of key innovations. Namely, all toxin families undergo shifts in their rates of evolution, likely in response to changes in adaptive optima. Furthermore, we show that rapid-pulsed evolution modelled as a Levy process better fits snake venom evolution than conventional early burst or Ornstein-Uhlenbeck models. While our results support the idea of snake venom being a key innovation, the innovation of venom chemistry lacks clear mechanisms that would lead to reproductive isolation and thus adaptive radiation. Therefore, the extent to which venom directly influences the diversification process is still a matter of contention.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"Royal Society"}]},"item_10001_relation_13":{"attribute_name":"PubMedNo.","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:pmid/32345154 ","subitem_relation_type_select":"PMID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1098/rspb.2020.0613","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://creativecommons.org/licenses/by/4.0/"}]}]},"item_10001_relation_17":{"attribute_name":"Related site","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://royalsocietypublishing.org/doi/10.1098/rspb.2020.0613","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"Rights","attribute_value_mlt":[{"subitem_rights":"© 2020 The Author(s)"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0962-8452","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"1471-2954","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"Author's flag","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-07-30"}],"displaytype":"detail","filename":"rspb.2020.0613.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","license_note":"Creative Commons Attribution 4.0 International(https://creativecommons.org/licenses/by/4.0/)","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"rspb.2020.0613","url":"https://oist.repo.nii.ac.jp/record/1655/files/rspb.2020.0613.pdf"},"version_id":"6d10bae5-004d-4413-bf80-ab08e0833bfd"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"gene expression evolution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"early burst","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"snake venom","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"complex traits","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"key innovation","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Toxin expression in snake venom evolves rapidly with constant shifts in evolutionary rates","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Toxin expression in snake venom evolves rapidly with constant shifts in evolutionary rates","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"30","path":["44"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-07-30"},"publish_date":"2020-07-30","publish_status":"0","recid":"1655","relation_version_is_last":true,"title":["Toxin expression in snake venom evolves rapidly with constant shifts in evolutionary rates"],"weko_creator_id":"30","weko_shared_id":30},"updated":"2023-06-26T11:45:48.406043+00:00"}
