Bats are interesting animals. They fly and make sounds to find food. A new study says bats originated in Europe about 65 million years ago. This is different from what scientists thought before. The study shows that bats spread from Europe to Africa, Asia, and other places. Scientists are studying bats to discover how they resist diseases. They want to know why bats do not get sick from some viruses. Bats help nature by pollinating plants and controlling insects. But many bat species are threatened. They face problems like climate change and habitat loss. It is important to protect bats.

A new study published in the journal Nature reveals that bats likely originated in Europe about 65 million years ago. This finding changes the previous belief that bats came from Africa, Asia, or North America. The research involved over 130 scientists who studied bat fossils and DNA from living bat species. They discovered that bats spread from Europe to Africa and then to Asia, the Americas, and Australia. Scientists are also trying to understand how bats resist diseases. Bats can carry dangerous viruses but do not get sick. This study helps us discover how bats can live with these viruses. Many bat species are threatened due to climate change and habitat loss. Protecting bats is important because they play a key role in ecosystems by pollinating plants and controlling insect populations.

A landmark study published in the journal Nature has revealed that bats likely originated in Europe about 65 million years ago, which significantly alters our understanding of their evolutionary history. Previously, scientists believed that bats evolved in Africa, Asia, or North America. The research team, consisting of over 130 international researchers, analyzed ancient bat fossils and genomic data from living species. Their findings indicate that the earliest bat ancestors dispersed from Europe into Africa and later spread to Asia, the Americas, and Australia. Additionally, the study highlights that echolocation and flight likely evolved early in bat history. Scientists are also investigating how bats resist diseases, as they are known to carry zoonotic viruses without suffering from them. This research could help us discover the genetic adaptations that allow bats to tolerate these viruses. However, many bat species are currently threatened due to climate change, habitat loss, and human persecution. Protecting bats is crucial because they contribute to ecosystems by pollinating plants and controlling insect populations, which helps maintain ecological balance.
