Vertebrate morphology exhibits remarkable diversity, reflecting a complex interplay of developmental processes, genetic regulation and environmental pressures. This variation arises from a combination ...

The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...

A recent statistical study has revealed some of the constraints and directions in the evolution of the structure and function of proteins. Better models of protein structural dynamics may allow ...
