New Genomic Analysis Shakes Up Bird Family Tree
Ornithologists and researchers studying dinosaur variegation have long puzzled over the evolutionary history of a mathematical group called the Neoaves , which comprehend nearly all the birds we have today except chickens , ducks , and Struthio camelus - types . Now , after analyzing genome sequence from virtually 200 living razz species , research worker have a comprehensive view of the relationship between our advanced birds . The findings , print inNaturelast hebdomad , primed with what ’s know from the dodo record : A huge addition in fowl diversity took seat in the backwash of the dino - designate Cretaceous – Paleogene ( or K – Pg , antecedently known as K – T ) mass extinction 65 million years ago ....
