Uncinate processes, lever-like structures attached to the ribs, may have helped many dinosaurs breathe a little easier
We used tell-tale markings on ribs to show that uncinate processes were widespread in dinosaurs and their relatives, and likely represent an ancient adaptation for improved respiration that was ultimately inherited by birds.

Losing the larval stage… one step at a time?
Amphibians have undergone important evolutionary transitions in reproductive modes and life-cycles. In our recent study, we compare large-scale macroevolutionary patterns in these transitions across the three major amphibian groups; frogs, salamanders and caecilians.
Genomic analysis of hypoxia inducible factor alpha in ray-finned fishes reveals missing Ohnologs and evidence of widespread positive selection
Fishes are increasingly challenged by low dissolved oxygen in nature and their survival relies, in part, upon their molecular responses. This study sheds new light on the evolution and diversity of the hypoxia inducible factor, the master regulator of oxygen-dependent gene expression, in fishes.
