Overview
A recent investigation, which constitutes the largest analysis of bat genomes and fossils to date, focused on unraveling the evolutionary origins of bats. The study aimed to clarify the emergence timeframe and geographic location of the earliest bats, as well as the initial development of echolocation within the species.
Findings
The comprehensive analysis of genetic and paleontological evidence indicated that the first bats appeared in Europe. This emergence is estimated to have occurred approximately 65 million years ago. Furthermore, the research suggested that echolocation, the biological sonar used by bats for navigation and hunting, evolved early in the evolutionary timeline of these mammals.
