A new study examined how bivalves -- the group that includes clams, mussels, scallops, and oysters -- evolved among many others in the period of rapid evolution known as the Cambrian Explosion. The team found that though many other lineages burst into action and quickly evolved a wide variety of forms and functions, the bivalves lagged behind. The study has implications for how we understand evolution and the impact of extinctions.

A new study led by scientists with the University of Chicago examined how bivalves—the group that includes clams, mussels, scallops, and oysters—evolved among many others in the period of rapid evolution known as the Cambrian Explosion. The team found that though many other lineages burst into action and quickly evolved a wide variety of forms and functions, the bivalves lagged behind.

Atmospheric pressure systems that reduced temperatures could be caused by climate change, say experts

A new paleontology study by UChicago researchers discovered that rock-boring clams, known as bivalves, vary in shape despite performing the same function. This paper is one of the first major studies done using three-dimensional images of bivalve shells. The Maroon sat down with scientists Katie S. Collins, Stewart M. Edie, and David Jablonski to talk...
