蝙蝠是全球生态系统中的关键角色，为植物授粉、传播种子并捕食大量昆虫。
Bats are critical players in global ecosystems, pollinating plants, dispersing seeds and eating huge numbers of insects. One of only three lineages of flying vertebrates in Earth’s history, there are more than 1,500 bat species living today. But their evolutionary history has been a bit of a puzzle for scientists.The largest combined bat genome and fossil study ever conducted is now bringing some clarity. Its findings indicate that these flying mammals first appeared in Europe about 65 million years ago, in the aftermath of the mass extinction event that doomed the dinosaurs, before spreading around the world, not in North America, Asia or Africa as previously hypothesized.The researchers assembled the largest collection of high-quality bat genomes to date, covering 103 species representing all 21 recognized families of bats. They integrated this data with an analysis of 44 fossil bats to decipher their evolutionary history and generate a bat family tree.

研究发现表明，这些飞行哺乳动物约在6500万年前首次出现在欧洲，即导致恐龙灭绝的大灭绝事件之后，随后扩散至全球，而非如先前假设的在北美、亚洲或非洲。
