Are transitional fossils evidence for evolution?

Transitional fossils are remnants of an organism that came in between a known version of a species and the current species. Allegedly, transitional fossils would be evidence for evolution because it would show intermediate forms of a species and they changed and accumulated adaptations at a slow pace.
