Conditions on Earth influenced evolution and how biodiversity changed through time. Place the following events in order from earliest to most recent.Brachiopods are shelled marine organisms that superficially resembled bivalves in that they are of similar size and have a hinged shell in two parts. However, ...The brachiopod shell grows by increments to the margin which typically are greater along the anterior and lateral margins and which form concentric growth lines on the outer surface. Thus the initial shell remains at or near the posterior margin and may form the tip of a

Brachiopods (BRACK-yo-pods) are an ancient line of shellfish, first appearing in the earliest Cambrian rocks, that once ruled the seafloors. After the Permian extinction nearly wiped out the brachiopods 250 million years ago, the bivalves gained supremacy, and today the brachiopods are restricted to cold and deep places.The Silurian Period. The Silurian (443.7 to 416.0 million years ago)* was a time when the Earth underwent considerable changes that had important repercussions for the environment and life within it. One result of these changes was the melting of large glacial formations. This contributed to a substantial rise in the levels of the major seas.
