Featuring a detailed chronogram that spans from the late Cretaceous period to the present, the visual data illustrates the classification of various avian groups including Palaeognathae, Galloanserae, and Neoaves. The study utilizes advanced molecular and morphological evidence to map the diversification of bird lineages over 70 million years, providing critical insights into the branching patterns of modern bird orders. By integrating fossil record estimations with systematic taxonomy, the work serves as a foundational reference for understanding the history of avian evolution and the hierarchical structure of bird species. The clear, illustrated classification scheme facilitates a deeper comprehension of how major clades, such as the Passeriformes and Aequorlitornithes, relate to their ancestral origins within the broader context of dinosaurian descendants. This academic overview is essential for researchers and students focused on ornithology and evolutionary biology, offering a precise visual representation of lineage development and divergence times.",{"@graph":14,"@context":66},[15,34,49],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/research-report/","Research & Report",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/phylogeny-of-birds-a-comprehensive-evolutionary-tree-analysis/618938/",4,{"url":32,"name":10,"@type":35,"author":36,"headline":10,"publisher":39,"fileFormat":42,"inLanguage":8,"description":12,"dateModified":43,"datePublished":43,"encodingFormat":42,"isAccessibleForFree":44,"interactionStatistic":45},"DigitalDocument",{"name":37,"@type":38},"\tJames","Person",{"url":19,"name":40,"@type":41},"DocShare","Organization","application/octet-stream","2026-10-20",true,{"@type":46,"interactionType":47,"userInteractionCount":4},"InteractionCounter",{"@type":48},"ViewAction",{"@type":50,"mainEntity":51},"FAQPage",[52,58,62],{"name":53,"@type":54,"acceptedAnswer":55},"What does the phylogenetic tree illustrate?","Question",{"text":56,"@type":57},"The tree illustrates the evolutionary relationships and divergence times among modern bird species, tracing their history from the late Cretaceous period to the present.","Answer",{"name":59,"@type":54,"acceptedAnswer":60},"What are some of the major avian groups mentioned?",{"text":61,"@type":57},"The document highlights several major groups including Palaeognathae, Galloanserae, and Neoaves, as well as specific orders like Passeriformes and Aequorlitornithes.",{"name":63,"@type":54,"acceptedAnswer":64},"What is the time scale covered in the analysis?",{"text":65,"@type":57},"The evolutionary chronogram covers a span of approximately 70 million years, beginning in the upper Cretaceous and extending through the Palaeogene and Neogene periods to the present day.","https://schema.org",{"og:url":32,"og:type":68,"og:title":10,"og:site_name":40,"og:description":12},"article",{"robots":70,"canonical":32},"index,follow",{"doc_id":72,"site_id":7},618938,1792462031,{"code":4,"msg":75,"data":76},"success",[77,81,85,89,94,99,104,108,113,116,120],{"id":22,"doc_module":4,"doc_module_name":25,"category_name":78,"show_sort_weight":79,"slug":80},"Story & Novel",90,"story-novel",{"id":26,"doc_module":4,"doc_module_name":25,"category_name":82,"show_sort_weight":83,"slug":84},"Literature",80,"literature",{"id":33,"doc_module":4,"doc_module_name":25,"category_name":86,"show_sort_weight":87,"slug":88},"Exam",70,"exam",{"id":90,"doc_module":4,"doc_module_name":25,"category_name":91,"show_sort_weight":92,"slug":93},5,"Comic",60,"comic",{"id":95,"doc_module":4,"doc_module_name":25,"category_name":96,"show_sort_weight":97,"slug":98},6,"Technology",50,"technology",{"id":100,"doc_module":4,"doc_module_name":25,"category_name":101,"show_sort_weight":102,"slug":103},7,"Healthcare",40,"healthcare",{"id":105,"doc_module":4,"doc_module_name":25,"category_name":29,"show_sort_weight":106,"slug":107},8,30,"research-report",{"id":109,"doc_module":4,"doc_module_name":25,"category_name":110,"show_sort_weight":111,"slug":112},9,"Religion & Spirituality",20,"religion-spirituality",{"id":111,"doc_module":4,"doc_module_name":25,"category_name":114,"show_sort_weight":111,"slug":115},"World Cup","world-cup",{"id":117,"doc_module":4,"doc_module_name":25,"category_name":118,"show_sort_weight":117,"slug":119},10,"Lifestyle","lifestyle",{"id":121,"doc_module":4,"doc_module_name":25,"category_name":122,"show_sort_weight":90,"slug":123},19,"General","general",{"code":4,"msg":75,"data":125},{"doc_id":72,"user_id":126,"nickname":37,"user_avatar":127,"doc_module":4,"category_id":105,"category_name":29,"doc_title":10,"doc_description":12,"doc_content":128,"file_id":129,"file_url":130,"file_type":131,"file_size":132,"view_count":4,"is_deleted":4,"is_public":22,"is_downloadable":22,"audit_status":22,"page_count":22,"language":133,"language_code":8,"site_id":7,"html_lang":8,"table_of_contents":134,"faqs":135,"seo_title":136,"seo_description":12,"update_tm":73,"read_time":30},2336474466412,"https://ap-avatar.wpscdn.com/davatar_155a257f0dc6eb9ab79c44ca47cae57d","RO Prum et al.
