When and where did bats first appear according to the study?

A large study combining bat genomes and fossils suggests that bats first appeared in Europe about 65 million years ago. This timing places their emergence shortly after the extinction of the dinosaurs.

What key evolutionary traits evolved early in bats?

The study indicates that the evolution of flight and echolocation, the biological sonar system many bats use, occurred near the dawn of bat evolution. These abilities are considered fundamental to their success and diversification.

How many bat species and fossils were analysed in the study?

Researchers analysed genomes from 103 different bat species and integrated this data with an analysis of 44 fossil bats. This extensive dataset was used to construct a comprehensive bat family tree.

Which continent have bats never inhabited?

According to the findings of the study, Antarctica is the only continent that bats have never inhabited. From their likely origin in Europe, they spread to other parts of the world.
