Missing link

"Missing link" is a term for a transitional form from the fossil record that connects two different species to an earlier ancestor. The missing link may have features common to both species; for example an early avian fossil could have feathers much like a modern bird but still retain the bony tail and teeth of a dinosaur. This would be considered a missing link between dinosaurs and birds.

The missing link is a popular and not a scientific concept. Scientists studying the fossil record have long known that not every species that lived was 'lucky' enough to leave behind a fossil. More importantly, populations are constantly changing and species are statistical constructs and not ideal-types; therefore, there is not scientific meaning to the notion of a "transitional form."
