	Monotreme - Wikipedia, the free encyclopedia
		Monotremes were very poorly understood for many years, and to this day some of the 19th century myths that grew up around them endure.
		It now seems plain that modern monotremes are the survivors of an early branching of the mammal tree; a later branching is thought to have led to the marsupial and placental groups.
		The key physiological difference between monotremes and other mammals is the one that gave them their name; Monotreme means 'single opening' in Greek, and comes from the fact that their urinary, defecatory, and reproductive systems all open into a single duct, the cloaca.

	Monotreme
		Monotremes are mammals that are best known for laying eggs, instead of giving birth to live young like marsupials and placental mammals (eutheria).
		Their metabolic rate is remarkably low by mammalian standards, alhough the extent to which this is a characteristic of monotremes, as opposed to an adaptation on the part of the small number of surviving species to harsh environmental conditions, is uncertain.
		Monotremes were very poorly understood for many years, and to this day some of the 19th century myths that grew up around them endure, particularly in the northern hemisphere.

	Monotreme - MSN Encarta
		Monotremes are native to Australia, Tasmania, and New Guinea.
		After monotreme eggs are hatched, the young are helpless, and, in the case of the echidna, are carried in shallow abdominal pouches.
		Young monotremes do not have mouth parts suitable for suckling; the liquid produced by the nippleless mammary organ is licked from the belly hair of the mother.

		MONOTREME [monotreme], name for members of the primitive mammalian order Monotremata, found in Australia, Tasmania, and New Guinea.
		Although monotremes possess the distinguishing mammalian features of hair and mammary glands, they are unique among mammals in laying eggs rather than giving birth to live young.
		Like birds and reptiles, monotremes have a single opening, the cloaca, for the passage of liquid and solid wastes, the transfer of sperm, and, in the female, the laying of eggs.

	Introduction to the Monotremata (Site not responding. Last check: 2007-10-22)
		Monotremes are not a very diverse group today, and there has not been much fossil information known until rather recently.
		In some ways, monotremes are very primitive for mammals because, like reptiles and birds, they lay eggs rather than having live birth.
		Like other mammals, however, monotremes have a single bone in their lower jaw, three middle ear bones, high metabolic rates, hair, and they produce milk to nourish the young.

	Monotreme - EvoWiki (Site not responding. Last check: 2007-10-22)
		The name monotreme means "one-holed," referring to the cloaca, a single hole that serves the urinary tract, anus, and reproductive tract in monotremes.
		Monotremes are considered very primitive for mammals because, like reptiles and birds, they lay eggs rather than having live birth.
		While monotremes lay eggs they also nurse their young with milk (like mammals, in fact the origin of the name Mammalia), but interestingly never evolved a nipple for delivering the milk and the milk oozes through pores in the mother's skin.

		Introduction -- What are monotremes Reptile-like and mammal-like features of monotremes Where do they fit in the evolution of mammals Introduction -- What are monotremes Monotremes are egg-laying mammals found in Australia and on the island of New Guinea (politically Papua-New Guinea in the east and the Indonesian province of Irian Jaya in the west).
		While the laying of eggs by the monotremes is the best-known and most obvious similarity that they have to the reptiles, there are a number of other similarities, which will be examined in the next section.
		One feature of monotremes which I don't know where it fits is the mechanism for sex determination: "The male is heterogametic, that is, he produces two kinds of sperm, as humans do, one with a Y chromosome and the other with an X chromosome...

		So monotremes vs. other recent mammals seem a good example for highways and sidetracks of the evolution, and we learn something by observing the details of mammalian evolution.
		Eutherians and monotremes are similar in the jaw and ear structure but not in the structure of molars.
		Metatherians and monotremes are similar in the original number of incisors, in the presence of epipubis, and in a number of plesiomorhic structures.

	eyeteeth: Their cousin called monotreme
		The platypus is the famous monotreme; less well known for some reason (though even weirder in my opinion) is the echidna, also known more descriptively as the spiny anteater.
		Monotremes are mammalian, even if what they have is a kind of free demo version of mammalianism without the really useful features like live birth, so they lactate.
		Monotremes are the oldest trunk of the mammal family tree.

		The specimen is a monotreme like the platypus and echidna, which, unlike other mammals, lay eggs and lack whiskers, teeth and external ears.
		"What is special about it is it has aspects that suggests monotremes split away from other mammals (such as the koala and wallaby) much earlier than we thought," the Melbourne Museum curator of vertebrate palaeontology, Tom Rich, said.
		Dr Rich said this phenomenon was called conversion evolution, where different ancestors produced the same evolutionary result.

	A Cretaceous symmetrodont therian with some monotreme-like postcranial features : Nature
		But unlike the closely related spalacotheroids and living therians, this new mammal revealed some surprisingly convergent features to monotremes in the lumbar vertebrae, pelvis and hindlimb
		These peculiar features may have developed as functional convergence to locomotory features of monotremes, or the presence of lumbar ribs in this newly discovered mammal and their absence in its close relatives might be due to evolutionary developmental homoplasy.
		Analysis including this new taxon suggests that spalacotheroids evolved earlier in Eurasia and then dispersed to North America, in concordance with prevailing geodispersal patterns of several common mammalian groups during the Early Cretaceous period.
