The idea that dinosaurs might be related to birds wasn\u2019t news at this point, but we didn\u2019t have evidence to prove it beyond anatomical similarities and skeletal data.<\/p>\n<p>So, armed with the bones of a 68-million-year-old <em>T. rex<\/em>, the team extracted the protein <a href=\"https:\/\/www.iflscience.com\/how-dinosaur-collagen-has-been-found-to-survive-for-195-million-years-75886\" target=\"_blank\" rel=\"noopener noreferrer\">collagen<\/a>, something that\u2019s found in the bones of animals alive today. This in itself was quite the discovery as it was the first time we realized how long this protein could survive for, so it represented an unprecedented opportunity to analyze dinosaur tissues.<\/p>\n<p>The collagen was detected using mass spectrometry, and the resulting peptide sequences could be used in a molecular analysis to search for similarities between it and the collagen of 21 extant species. The team then used these results to create family trees that could paint a picture of <em>T. rex<\/em>\u2019s relatedness to the various animal groups. These trees came together in a myriad of ways, creating multiple results that could be compared against one another.<\/p>\n<div class=\"fr-image-container no-background\" data-asset-id=\"80470\" data-reactroot=\"\">\n<div class=\"fr-image\"><picture title=\"\"><source media=\"(min-width: 1000px)\" srcset=\"https:\/\/assets.iflscience.com\/assets\/articleNo\/76957\/iImg\/80470\/closest-living-relative-t-rex-l.webp\" type=\"image\/webp\"><source media=\"(min-width: 1000px)\" srcset=\"https:\/\/assets.iflscience.com\/assets\/articleNo\/76957\/iImg\/80470\/closest-living-relative-t-rex-l.png\" type=\"https:\/\/www.iflscience.com\/image\/png\"><source media=\"(min-width: 568px)\" srcset=\"https:\/\/assets.iflscience.com\/assets\/articleNo\/76957\/iImg\/80470\/closest-living-relative-t-rex-m.webp\" type=\"image\/webp\"><source media=\"(min-width: 568px)\" srcset=\"https:\/\/assets.iflscience.com\/assets\/articleNo\/76957\/iImg\/80470\/closest-living-relative-t-rex-m.png\" type=\"https:\/\/www.iflscience.com\/image\/png\"><source media=\"(max-width: 567px)\" srcset=\"https:\/\/assets.iflscience.com\/assets\/articleNo\/76957\/iImg\/80470\/closest-living-relative-t-rex-s.webp\" type=\"image\/webp\"><source media=\"(max-width: 567px)\" srcset=\"https:\/\/assets.iflscience.com\/assets\/articleNo\/76957\/iImg\/80470\/closest-living-relative-t-rex-s.png\" type=\"https:\/\/www.iflscience.com\/image\/png\"><img decoding=\"async\" class=\"inline-image fr-fic fr-dib\" data-asset-id=\"80470\" src=\"https:\/\/assets.iflscience.com\/assets\/articleNo\/76957\/iImg\/80470\/closest living relative to t rex.png\" alt=\"A T. rex footprint (left) compared to that of a chicken (middle), and an ostrich.\" title=\"A T. rex footprint (left) compared to that of a chicken (middle), and an ostrich.\" loading=\"lazy\"\/><\/source><\/source><\/source><\/source><\/source><\/source><\/picture><\/div><figcaption class=\"fr-figcaption\">\n<p>A <em>T. rex<\/em> footprint (left) compared to that of a chicken (middle), and an ostrich.<\/p>\n<div class=\"fr-reference\" style=\"text-align: left;\">Image credit: Topimages \/ Sriyana \/ Shutterstock.com \/ David Bygott via <a href=\"https:\/\/www.flickr.com\/photos\/davidbygott\/4154298808\" target=\"_blank\" rel=\"noopener noreferrer\">Flickr<\/a>, <a href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/2.0\/\" target=\"_blank\" rel=\"noopener noreferrer\">CC-BY-NC-SA 2.0<\/a> edited by IFLScience<\/div>\n<\/figcaption><\/div>\n<p>Most of their approaches placed <em>T. rex<\/em> firmly within the Archosauria, which is a group shared by birds and crocodilians, but it was leaning in favor of the birds. This means the collagen itself most closely resembled that of chickens and ostriches, rather than those very dinosaur\u2019ish-looking crocodilians, though the authors did express that there were gaps in the data that made it hard to create a full picture.<\/p>\n<p>So, it seems we come to the big question: What is the closest living relative to <em>T. rex<\/em>? From what we know so far, it\u2019s a bird, most likely either a chicken or ostrich.<\/p>\n<p>At last, it seemed the birds are dinosaurs debate had been settled, as the authors concluded that if similar biomolecules for non-avian dinosaurs were processed in the same way, they too would reveal a higher degree of similarity with birds than any other vertebrate.<\/p>\n<p>\u201cOur results at the genetic level basically agree with what has been seen in skeletal data,\u201d study author John M Asara of Harvard University told the <a href=\"https:\/\/www.nytimes.com\/2008\/04\/25\/science\/25dino.html\" target=\"_blank\" rel=\"noopener noreferrer\">New York Times<\/a> when the news broke. \u201cThere is more than a 90 percent probability that the grouping of <em>T. rex<\/em> with living birds is real.\u201d<\/p>\n<blockquote class=\"tiktok-embed\" cite=\"https:\/\/www.tiktok.com\/@kristopher.berry\/video\/6992970508191010054\" data-video-id=\"6992970508191010054\" style=\"width: 325px; max-width: 325px;float: none!important; margin: 0;padding: 0;\" id=\"v52082686006567820\"><p><iframe name=\"__tt_embed__v52082686006567820\" sandbox=\"allow-popups allow-popups-to-escape-sandbox allow-scripts allow-top-navigation allow-same-origin\" src=\"https:\/\/www.tiktok.com\/embed\/v2\/6992970508191010054?lang=en-GB&amp;referrer=http%3A%2F%2Fadmin.iflscience.qa%2Farticles%2F76957%2Fedit\" style=\"width: 100%; height: 757px; display: block; visibility: unset;\"><span class=\"fr-mk\" style=\"display: none;\">\u00a0<\/span><span class=\"fr-mk\" style=\"display: none;\">\u00a0<\/span><span class=\"fr-mk\" style=\"display: none;\">\u00a0<\/span><\/iframe><\/p><\/blockquote>\n<p><span class=\"social-disclaimer-icon\">\u24d8\u00a0<\/span><span class=\"social-disclaimer\">IFLScience is not responsible for content shared from external sites.<\/span><\/p>\n<p>The result will no doubt make sense to anyone who&#8217;s ever lived with chickens and seen the remarkable way they run, whether in an attempt to flee or in pursuit.
