Fossils or organisms that show the intermediate states between an ancestral form and that of its descendants are referred to as transitional forms. There are numerous examples of transitional forms in the fossil record, providing an abundance of evidence for change over time.
A lack of transitional forms would have suggested some flaw in the fundamentals of evolutionary theory. At least, we would have expected some transitional forms to be found, if either gradualism or punctuated equilibrium was the correct model for evolution. As it is, more than enough transitional forms have been found to date to satisfy any objective observer.
Transitional phrases are essential to good flow in an essay."In addition" is an example of a transitional phrase.Caterpillars are a transitional step in the life of a butterfly.
False, there are many transitional forms in the fossil record. Osteolepis Eusthenopteron Panderichthys Tiktaalik Elginerpeton Obruchevichthys Ventastega Acanthostega Ichthyostega Hynerpeton Tulerpeton Pederpes Eryops Pedopenna Anchiornis Archaeopteryx Confuciusornis Ardipithecus ramidus Australopithecus afarensis Australopithecus africanus Australopithecus anamensis Australopithecus garhi Australopithecus aethiopicus Australopithecus boisei Australopithecus robustus Homo habilis Homo rudolfensis To name a few.

Transitional epithelium forms the lining of the bladder. These cells are able to change shape, allowing the bladder to stretch as it fills with urine and then return to its original shape as the urine is voided.

Numerous transitional forms have so far been found. In the clade of apes alone, the number of intermediate fossils is large enough to allow for a near-complete understanding of the evolutionary history of Man and the other apes.
There is no specific scientific name for the concept of the "missing link" in human evolution. It is a colloquial term that has been used in the past to describe hypothetical transitional forms in the evolutionary lineage of humans. Scientists now understand that evolution is a complex and continuous process with many transitional forms, rather than a single missing link.
Specialized cells called transitional cells form the lining of the urinary bladder.

That would be transitional epithelium. Transitional Epithelium is specialized to change in response to increased tension. It forms the inner lining of the urinary bladder and lines the ureters, and part of the urethra. It protects and has distensibility.
Reticulocytes were first described as transitional forms of red blood cells by Wilhelm H. Erb in 1865.
