One of the key ideas in evolution is that there is a fairly smooth transition from one species of animal to another. So, there should have been a whole lot of animals in between fish and reptiles, and similarly between dinosaurs and birds. This should mean that there are lot of fossils of these intermediate animals. The question is—do these fossils exist? It feels like a little bit of a detective story, looking for the links in the chain. How does the evolutionary process work and why would we be looking for these fossils in the middle between different animals? Find out in this program.
