What is a brachiopod.

Despite many major advances in recent years, three key challenges remain in bringing clarity to the early history of the phylum: (1) identifying the origin, morphology and life modes of the first brachiopods; (2) understanding the relationships of the major groups to each other and higher sister taxa; and (3) unravelling the roles of the Cambrian and …

Brachiopods are an ancient group of organisms, at least 600 million years old. They might just look like clams, but they are not even closely related.
