	Transitional fossil - Wikipedia, the free encyclopedia
		"A transitional fossil or transitional form is the fossilized remains of a life form that illustrates an evolutionary transition.
		According to modern evolutionary theory, all populations of organisms are in transition.
		Therefore, a "transitional form" is a human construct that vividly represents a particular evolutionary stage, as recognized in hindsight.

	Evolution Fossil Record
		A transitional fossil is the fossil remains of a creature that exhibits primitive traits in comparison with the more derived life-forms it is related to.
		There is virtually nothing in the fossil record that can be used as evidence of a transitional life form When apparent examples of useful mutations are examined thoroughly, it becomes clear that no transitional creatures exist anywhere in the fossil record.
		What we see in the fossils, according to this view, are only the twigs, the final end-products of evolution, while the key transitional forms which would give a clue about the origin of major animal groups remain completely hidden.

	Transitional Fossils FAQ
		I won't go into the transitions from cotylosaurs to the advanced anapsid reptiles (turtles and possibly mesosaurs), to the euryapsid reptiles (icthyosaurs, plesiosaurs, and others), or to the lepidosaurs (eosuchians, lizards, snakes, and the tuatara), or to most of the dinosaurs, since I don't have infinite time.
		Transitional fossils from early eutherian mammals to the carnivores:
		Typically, the only people who still demand to see transitional fossils are creationists who have been reading 100-year-old anti-evolution arguments, and who are either unaware of the currently known fossil record or are unwilling to believe it for some reason.

	Creation Science Issues, Transitional Fossils
		Transitional fossils, or the supposed lack thereof, has been used for many years by anti-evolutionists to argue against evolution.
		The lack of these "transitional" fossils is proof to young earth creationists that evolution is false.
		Naturally, they will say, "Where are the transitional fossils between these transitional fossils?" If we had a clear fossil record, showing progression every 10,000 years for millions of years, they will not believe it, and will want the "transitional" fossils for the missing 10,000 year period.

	Chapter 7: Transitional Forms
		Fossil coelacanths appeared to be closely related to amphibians, based on their skeletal structure, which is all that was fossilized.
		Transitional forms are sometimes referred to as "missing links." On the other hand, "The Missing Link" is the name given to the hypothetical fossil that many hope will some day prove beyond a doubt that man descended from animals.
		It may be argued that the lack of transitional fossils is no problem to evolution, because evolution happened by large jumps or "rapid branching," as punctuated equilibrium claims.

	Fossil Record
		He was particularly impressed by the fact that the fossil creatures found in any region often bore resemblances to the living species in the same regions, yet were quite unlike both the fossils and the living species encountered in other very similar regions of the world.
		The hallmark of a transitional form is that, since it contains features from two different types, it is difficult to classify as one or the other.
		Darwin's explanation for this was that the transitional fossils were out there, but the known fossil record was so incomplete that they just hadn't been found yet.

	What Is A Transitional Fossil?
		A transitional fossil is any fossil which gives us information about a transition from one species to another.
		A transitional fossil is one that falls between the two piles.
		Some parts of the fossil record are good, in the sense that they provide a large number of well-preserved fossils, nicely spread out across spans of time.

	There are no transitional fossils
		Transitional fossils can occur between groups of any taxonomic level, such as between species, between orders, etc. Ideally, the transitional fossil should be found stratigraphically between the first occurrence of the ancestral lineage and the first occurrence of the descendent lineage..."
		When an effort is made to explain the fossil record (whether it be taxonomic differences or changes in response to ecological factors) in terms of Darwinian evolution the concept of uniformitarianism is essential, for it allows us to use the present to explain the past.
		Such transitional forms are scarce, to be sure, and for two sets of good reasons - geological (the gappiness of the fossil record) and biological (the episodic nature of evolutionary change, including patterns of punctuated equilibrium and transition within small populations of limited geographic extent).

	RE: Isisfordia duncani - transitional fossil and more
		Transitional fossils would be a series of mosaics demonstrating a progress from the former to the latter.
		This oddity has been attributed to gaps in the fossil record which gradualists expected to fill when rods strata of the proper age had been found, In the last decade, however, geologists have found rock layers of all divisions of the last 500 million years rid no transitional forms were contained in them.
		Transitional implies from one sort of organism to another; this appears to be one Crocodyliforme among numerous and widely varying previously existing Crocodyliformes, of which a few forms currently exist.

	Resource of the American Scientific Affiliation: Taxonomy, Transitional Forms, and the Fossil Record by Keith B. Miller
		Even within well-preserved fossil series it is usually difficult to distinguish the record of speciation occurring within a particular depositional basin (or environment) from the effects of immigration of new species from outside that basin.
		As a result, for lineages with a good fossil record, the appearance of a new higher taxon is associated with the occurrence of species whose taxonomic identities are uncertain or whose morphologies converge closely on that of the new higher taxon.
		The transition in jaw articulation from reptiles to mammals is particularly illustrative of the appearance of a class level morphologic character (Fig.

	Problems with Evolutionary Explanations of the Fossil Record
		Transitional forms are a prediction of naturalistic evolutionary theory and the question we shall be asking is, "are predicted transitional forms found in the fossil record?" In some cases the challenges to the mechanism for such evolution will also be discussed.
		The absence of transitional fossils in the gaps between each group of fishes and its ancestor is repeated in standard treatises on vertebrate evolution.
		Despite this alleged transitional fossil which bears a striking resemblance to many living forms, the origin of the defining characteristics of tetrapods, the limbs, is still an unsolved mystery to evolutionists.

	The Austringer » The Transitional Fossil Existence Challenge (2005/02/24)
		By making a universal claim concerning transitional fossils, the anti-evolutionist should be prepared to back up the claim with extended technical discussion of the reasons why all sequences that others believe to be transitional in nature really are not transitional.
		In strict logical and probabilistic terms a fossil can’t be proven to be the direct ancestor of any living species, but this goes for any old bones being ancestral to any living individual today that you don’t have a documented pedigree for.
		Rather than claim transitional fossils dont exist, the skeptic merely has to demand that the evolutionist provide examples of these transitional fossils and explain why they are seen as some transition rather than the imaginative interpretation of fossils of different TYPES of the same KIND of animals.

		It is represented by fossil remains that display teeth, three claws on each wing, a flat sternum (breastbone), belly ribs (gastralia), and a long, bony tail.
		Therefore, either Archaeopteryx is not a transitional fossil (since birds already existed at the same time and there was nothing to “transition” into) or rock strata can not be accurately dated.
		Four leading American paleontologists examined the Sinosauropteryx fossils, and declared that its “feathers” were actually long parallel arrays of fibers that lack the branching pattern of modern feathers.

		There are some good reasons to suppose that these people do not quite have the wherewithal to back up their claims, like the existence of transitional fossils.
		The first two sets are called "transitional individuals", because the record is essentially complete enough that one can see each gradual shift in the transition.
		Please note that unfamiliarity with the reference above is a tacit failure of the claim of absence of transitional sequences -- the claim requires complete knowledge of fossil sequences, and unfamiliarity with any is prima facie evidence that the claimant doesn't have the basis for the claim.

	No Transitional Fossil Records - Creationism Myth

		All transitional means is that the child population has some characteristics of its parents, but that the species did not "finish" changing at that point.
		Now that the "current state" of moths is orange, the fl moths become the "transitional state" between the original white and the final orange.

		The fossils we did have were either too old (belonging to the Crocodyliformes and not sharing many features with modern crocodiles), or too young (80 or so million years).
		A transitional fossil is the fossil remains of a creature that exhibits certain primitive (or basal) traits in comparison with its more derived descendants.

	Dispatches from the Culture Wars: Transitional Fossil Evidence Challenge
		It was developed many years ago in response to the constant claim that there are no transitional fossil sequences in the world.
		In order to credibly make such a claim, of course, one would have had to examine all of the published instances where a fossil was advanced as transitional in the scientific literature and found that the conclusion was unwarranted.
		The challenge, for those who deny the existence of transitional sequences, is to show why the examples do not, in fact, show transition.
