Read the text and answer the questions.A bizarre Jurassic maniraptoran from China with elongate ribbon-like feathersRecent coelurosaurian discoveries have greatly enriched our knowledge of the transition fromdinosaurs to birds, but all reported taxa close to this transition are from relatively well knowncoelurosaurian groups. Here we report a new basal avialan, Epidexipteryx hui gen. et sp. nov.,from the Middle to Late Jurassic of Inner Mongolia, China. This new species is characterizedby an unexpected combination of characters seen in several different theropod groups,particularly the Oviraptorosauria. Phylogenetic analysis shows it to be the sister taxon toEpidendrosaurus, forming a new clade atthe base of Avialae. Epidexipteryx also possesses twopairs of elongate ribbon-like tail feathers, and its limbs lack contour feathersfor flight. This finding shows that a member of the avialan lineage experimented withintegumentary ornamentation as early as the Middle to Late Jurassic, and provides furtherevidence relating to this aspect of the transition from non-avian theropods to birds.Fucheng Zhang.

Answer 1

Del texto A Bizarre Jurassic Maniraptoran from China, nos exponen la relación entre esta nueva especie y el Epidendrosaurus.

• (Opción C) They have the same phylogenetic origin.

Con respecto al texto de A Bizarre Jurassic Maniraptoran from China, podemos ver que la relación principal entre la nueva especie descubierta en China y el Epidendrosaurus, es que ambas especies tienen el mismo origen filogenénitico; por lo que, dicha especie puede estar relacionado con una evolución del mismo.
