However, a 2021 analysis of mitochondrial genes among Accipitrimorphae, which include Cathartiformes, reinforced prior findings on the phylogenetic relationships between Cathartiformes and other subfamilies of Accipitriformes.
This statement was contradicted by a 2021 study examining mitochondrial genes among Accipitrimorphae, including Cathartiformes, which reinforced prior research on the phylogenetic relationships between Cathartiformes and other subfamilies within Accipitriformes.
