A transitional fossil is the fossil remains of a creature that exhibits certain primitive (or basal) traits in comparison with its more derived descendants. "Missing link" is a popular term used for transitional forms. 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.
That is better. The definition is tied in which the assumption that evolution occurs in the TOE sense. For a transitional fossil to exist evolution must be presumed to occur. If it wasn't then there would be no talk of "derived descendants". Thus it is not a scientific definition as such but an evolutionary science definition
So Iano, do transitional fossils exist that meet the criteria of the scientific definition? A simple yes or no eh?
Had you worded it so...
"So, Iano, do fossils exist that meet the criteria of the evolutionary scientific definition of transitional fossils. A simple yes or no eh?"
..then I would have answered a hearty yes
