   Genomes and Fossils Trace Bat Origins to Europe

   Bats originated in Europe approximately 65 million years ago, according to a study utilizing reference genomes and fossil records. This finding revises the known phylogeny and biogeography of the bat family, altering the established understanding of the mammalian family tree. The research clarifies the murky origins of these animals, who are the only mammals capable of true powered flight.

   Why it matters

   Bats comprise more than 1,500 species globally and represent one fifth of all mammal species. Most species use sound to hunt and navigate in total darkness. Understanding their early evolution helps scientists map how mammals diversified after the extinction of dinosaurs.

   What is confirmed

   • Bats originated in Europe approximately 65 million years ago.
   • The study used reference genomes and fossils to revise bat family phylogeny and biogeography.
   • Bats are the only mammals capable of powered flight.

   What to watch next

   • Further fossil discoveries in Europe from the late Cretaceous or early Paleogene
   • Peer review of the genomic sequencing methods used to date the lineage
