	Anseranatidae - EvoWiki (Site not responding. Last check: 2007-09-19)
		Anseranatidae is a monotypic clade within the Anseriformes, currently only containing the Magpie goose.
		As currently understood, Anseranatidae is the sister group to all other anseriformes with the exclusion of screamers (Livezey 1997, Ericson 1997).
		Although the distribution of those characters is still in question (Cracraft 2001), Dyke's (2001) cladistic analysis failed to support relationship between Anseranatidae and Anatalavis as proposed by Olson, instead placing it as the sister to the clade formed by the Presbyornithidae and Anatidae.

		The three perching ducks in the genus Nettapus are named as Pygmy Geese, eg Cotton Pygmy Goose, Nettapus javanica, but are true ducks.
		The odd Magpie Goose is in a family of its own, the Anseranatidae.
		Goose in its origins is one of the oldest words of the Indo-European languages, the modern names deriving from the proto-Indo-European root, ghans, hence Sanskrit hamsa (feminine hamsii), Latin anser, Greek khén etc.

	ANATIDAE FACTS AND INFORMATION
		Anatidae is the biological family that includes the ducks and most duck-like waterfowl, such as geese and swan.
		The Magpie_Goose is no longer considered to be part of the Anatidae, but is placed in its own family Anseranatidae.
		These are birds that are modified for swimming, floating on the water surface, and in some cases diving in at least shallow water.

		Traditionally, these were united as the "Anseranatidae." However, it seems that these two forms actually do not form a clade, but are merely successive goose-like branches from a basic goose-like stem [D00] [D01].
		If so, "Anseranatidae" is the paraphyletic parent of Anatidae.
		The notation "[L97*]" indicates an apomorphy based on the osteological dataset of [L97] run under PHYLIP with all characters unordered.

		>The Eocene specimen is described as a new species, Anatalavis oxfordi, and >the genus Anatalavis is transferred from the form-family Graculavidae to a >new subfamily, Anatalavinae, of the Anseranatidae.

	BIRD STUFF AND CLADISTICS
		This conflicts with the intuitive approach and shows rather convincingly that phylogenetic systematics is more reliable in producing phylogenies.
		Also related to this issue, Presbyornithidae and Anseranatidae (magpie goose) are to the first two anseriform to appear in the fossil record (around 70 million years; I think that there may be some Anatidae material from late K too) while the more basal Anhimidae (screamers; very similiar to fowl) doesn't appear until the Eocene!
		Galliforms (fowl) appear in the Cretaceous but are rather fragmentary so you can dispute this the way that John Jackson does and argue that more derived anseriforms (Anatidae, Presbyornithidae, Anseranatidae) appeared first and led to Anhimidae which led to Galliformes (which I think are the nearest relatives to anseriform now).

		Garrod (1873d, 1874a) placed screamers with his order "Galliformes" while it was Seebohm (1889) who lent the idea credulity with his elaboration of a galliform/anseriform nexus via the Anhimidae, as noted earlier.
		There are significant morphological and behavioral similarities between screamers and the monotypic Anseranatidae, noted by Delacour (1954) and Olson and Feduccia (1980b).
		Olson and Feduccia (1980b) reviewed the history of screamer relationships and noted that at best the alleged similarities between these birds and galliforms are superficial, relating primarily to the highly aberrant morphology of the Anhimidae (e.g., its chicken-like bill).

		If you find this encyclopedia or its sister projects useful,
		The order Anseriformes contains about 150 species of bird in three families: the Anhimidae (the screamers), Anseranatidae (the Magpie Goose), and the Anatidae, which includes over 140 species of waterfowl, among them the ducks, geese, and swans.
		All species in the order are highly adapted for an aquatic existence at the water surface.

	Anseriformes - EvoWiki
		Anseriformes (Wagler, 1830) is an order of aquatic birds including Anhimidae (screamers), Anseranatidae (a monotypic family whose sole member is the magpie goose, Anseranas semipalmata), Anatidae (including true ducks, geese, and swans) and the extinct family Presbyornithidae.
		With a some exceptions, it is now widely believed that anseriforms share most recent common ancestry with the Galliformes, or land fowl, forming a clade referred to as Galloanserae.

		Another possibility is that the screamers are the sister group of the Anseranatidae + Anatidae.
		I am not arguing one hypothesis over another here, but merely pointing out that alternative hypotheses of this sort can best be evaluated with cladograms showing the distribution of characters among taxa.
