Reconstructing ancestral enzymes has revealed that a switch in kinase substrate preference evolved via an expanded specificity intermediate that is tolerated in vivo, thus providing a path for kinase diversification.
Deep mutational scanning was used to comprehensively quantify the effects of mutations to influenza hemagglutinin and shows that the virus possesses a high inherent mutational tolerance at key antigenic sites.

The convergent evolution of unusually strict substrate specificity in apicomplexan LDHs arose by classic neofunctionalization of a duplicated MDH gene via few mutations of large effect.
Metabolic exaptation of an anaplerotic nitrogen cycle between bundle sheath and mesophyll cells may explain the remarkably frequent convergent evolution of C4 photosynthesis.

The N-terminal domain in histone 2A serves as an evolutionary tool to enable greater chromatin compaction when genome size is disproportionately larger than the nuclear volume across eukaryotes.
