A study published in the Nature journal alters how the evolution of fish has been historically understood. Fossilized fish and other sea creatures have often been pivotal in new scientific discoveries ...

A trade-off between tooth size and jaw mobility has restricted fish evolution, Nick Peoples at the University of California Davis, US, and colleagues report in the open-access journal PLOS Biology.

It's not what you do, it's how readily you do it. Rapid evolutionary change might have more to do with how easily a key innovation can be gained or lost rather than with the innovation itself, ...
