A transitional organism is a fossil species that exhibits characteristics of both ancestral and derived groups, providing evidence of evolutionary transitions between major groups of organisms. These transitional fossils help to illustrate the gradual changes that occurred over time, supporting the theory of evolution.

What kind of tissue is transitional tissue?
Transitional tissue is a type of epithelial tissue.
How many transitional forms does a fossil record contain?
"Transitional form" is an arbitrary term because every organism, whether living or fossil, is a link in the chain between an ancestral organism and a descendent. The break into new species is gradual rather than sudden. Every fossil is therefore a "transitional form" in the strict sense.In general, "transitional form" is used specifically to link one modern species with its prehistoric ancestor. In some cases, a form may not be a specific ancestor of an identifiable living species, but it may have general characteristics that indicate the evolutionary path that was being followed. E.g. the bird fossil Confuciusornis may not be ancestral to living birds, but it still indicates the direction of evolution from earlier repties.There are abundant transitional forms that illustrate e.g. the transition from fish to land animals; the transition from amphibians to reptiles; the transition from dinosaurs to birds; and the transition from early apes to humans.Because the definition of "transitional form" in the narrow sense (a transition between two set organisms) is variable, it's not possible to give a strict number.
What part of the urinary system contains transitional epithelium?
the ureter has three layers, transitional epithelium is one of them. the bladder also has transitional epithelium. In the urethra near the bladder it becomes transitional epithelium also. For those of you at Paris jr college, you can fine the on page 986-987 the 8th edition for A & P.
What is value of a transitional fossil?
A transitional fossil has evidence of an organism that had lived with different traits from different species. For example, the skeleton of Basilosaurus isis found in an Egyptian desert in 2005 has a whalelike body but also the limbs of land animals. Basilosaurus isis might be a transitional fossil from an ancient, giant land animal to a more recent whale.Transitional fossils display features of two types of animals and are examples of the transition from one type of animal into another. They are also known intermediate fossils, and serve to "bridge the gap" in evolutionary history between two types of related animals. They can be identified by their retention of certain primitive traits in comparison with their more derived relatives.According to modern evolutionary synthesis, all populations of organisms are in transition. Therefore, a "transitional form" is a human construct of a selected form that vividly represents a particular evolutionary stage, as recognized in hindsight. Contemporary "transitional" forms may be called "living fossils", but on a cladogram representing the historical divergences of life-forms, a "transitional fossil" will represent an organism near the point where individual lineages (clades) diverge.One example of a transitional fossil is one of Tiktaalik, a prehistoric fish. It contains features of fish such as fins, scales, and gills, but it has a flat head, lungs, weight bearing wrist bones, and a mobile neck like a tetrapod. Since it is found in just the right rock later, Tiktaalik represents one evolutionary stage in the transition from fish to tetrapods.
What is the location of stratified transitional?
Stratified transitional epithelium can typically be found lining areas of the body that are subject to stretching or expansion, such as the urinary bladder, ureters, and parts of the urethra.
What does transitional organism mean?
A transitional organism is an organism that exhibits traits of two different evolutionary stages, showing the evolutionary link between two related species. These organisms can provide valuable insights into how certain traits or features evolved over time. Examples include Archaeopteryx, a transitional species between reptiles and birds, and Tiktaalik, a transitional species between fish and tetrapods.
