Brown trout is one species that takes three forms, which differ in their migration habits. There appears to be no genetic difference between them. The common pipistrelle bat however was thought to be one species but is now known to be two. Genomics will help to reveal more about how this split occurred.


A favourite find in rock pools, the common starfish is more like us than we might think. They produce a hormone linked to puberty that is helping us to understand our evolutionary development. Starfish can also regenerate limbs, so studying their genome could help with medical advances for our species.
