| | + | The second criticism of the ''Archaeopteryx'', that it is not a transitional form, has been strengthened by the work of anatomist Dr. David Menton<ref>http://www.answersingenesis.org/home/area/bios/d_menton.asp</ref> suggesting that ''Archaeopteryx'' is a true bird with flight feathers, not a transitional form at all. In 1994, an article explained that the ''Archaeopteryx'' was essentially a flying bird, with a large [[cerebellum]] and [[visual cortex]]. The fact that it had teeth is irrelevant to its alleged transitional status -- a number of extinct birds had teeth, while many reptiles do not (the South American [[hoatzin]], ''Opisthocomus hoazin'', also shares with ''Archaeopteryx'' clawed digits in its wings, albeit as juveniles). Furthermore, like other birds, both its maxilla (upper jaw) and mandible (lower jaw) moved. In most vertebrates, including reptiles, only the mandible moves. |
