The similarities between the two groups of vultures are due to convergent evolution, rather than a close relationship. They were widespread in both the Old World and North America during the Neogene. Old World vultures are probably a polyphyletic group within Accipitridae, belonging to two separate not closely related groups within the family. [2]
Vultures are a result of convergent evolution: both Old World vultures and New World vultures eat carrion, but Old World vultures are in the eagle and hawk family (Accipitridae) and use mainly eyesight for discovering food; the New World vultures are of obscure ancestry, and some use the sense of smell as well as sight in hunting. Birds of both ...
Aegypiinae is one of two subfamilies of Accipitridae that are referred to as Old World vultures, the other being the Gypaetinae.They are not closely related to the Gypaetinae, and are instead a sister group to the serpent-eagles (Circaetinae).
A vulture is a bird of prey that scavenges on carrion.There are 23 extant species of vulture (including condors). [2] Old World vultures include 16 living species native to Europe, Africa, and Asia; New World vultures are restricted to North and South America and consist of seven identified species, all belonging to the Cathartidae family.
The griffon vulture is 93–122 cm (37–48 in) long with a 2.3–2.8 m (7 ft 7 in – 9 ft 2 in) wingspan. In the nominate race the males weigh 6.2 to 10.5 kg (14 to 23 lb) and females typically weigh 6.5 to 10.5 kg (14 to 23 lb), while in the Indian subspecies (G. f. fulvescens), the vultures average 7.1 kg (16 lb).

Traditionally considered an Old World vulture, it actually forms a separate minor lineage of Accipitridae together with the Egyptian vulture (Neophron percnopterus), its closest living relative. It is not much more closely related to the Old World vultures proper than to, for example, hawks , and differs from the former by its feathered neck.
