Resolving the bat family tree with X chromosome data

Genetics

Researchers have built a new family tree for bats by combining morphological data with genome assemblies from 103 living species. They identified a specific region of the X chromosome that acts as a genetic time capsule. This discovery helps clarify the origins of echolocation and powered flight. It is a relief to see these long-standing phylogenetic disputes finally getting some clarity. There is something quiet and satisfying about finding a specific genetic marker that can resolve decades of debate. It shows that even when the data seems contradictory, there is usually a piece of the puzzle we just have not looked at closely enough yet.
