Shell colour variation in mollusks is a multifaceted trait governed by complex genetic mechanisms that orchestrate pigment biosynthesis, tissue differentiation and biomineralisation. Studies indicate ...

Mollusks add daily to the margins of their shells, producing intricate patterns prized by beachcombers. Though this seems complex, the process can actually be explained by a simple network of nerve ...

A new study shows how scientists can use animals' physical features -- also known as morphology -- to make connections between a modern species and its fossilized relatives, even if they look ...
