When did bats originate? What did bats look like in the ancient times?

It is difficult to locate bat fossils. This is because their bones are light. However, our discoveries have given us some understanding of how long they have existed. The earliest bat fossils date back 520000 years ago. They were discovered in Wyoming, USA in 2003.

Based on the physical appearance of early bat fossils, they were always able to fly. In the past, several theories suggested that they were once land animals. Then, through evolution, they transformed their four limbs into wing-like appendages. However, there is no evidence from these fossil finds that bats underwent such a change.

Unlike the bats we know today and these early species, they were able to fly successfully in a different way. Early fossils show that their limbs had five claws each. Today, most species have two claws on their limbs. From these fossil remains, their hind legs were once much longer than those of today's species. Ironically, the forelimbs were shorter than today, but longer than they are today.

The earliest bat fossils date back 520000 years ago.

This change demonstrates that through the evolution of bats, balance was achieved in these limbs. However, why the hind limbs became shorter and the forelimbs longer is still a mystery. Perhaps to help them gain greater speed and control while flying?

The shorter wings on fossil remains clearly tell us that early bats couldn’t fly as fast as they do today. This is an evolutionary process and a reason that helped them survive in a constantly changing environment. People also believe that bats flew less frequently millions of years ago.

However, a significant form of bat evolution is the way they communicate. They use echolocation, but there are no inner ears in these early fossils that could do this. Therefore, it can be reasonably said that this is a survival method that evolved and developed over time in order for bats to have the best chance of survival.

In fact, female bats can delay the interaction of sperm with eggs from males to their eggs, which may be part of the evolutionary process of these animals. Some species mate in spring. However, females will prevent sperm from meeting eggs until autumn. This gives their children the best chance of survival, which is the whole of the evolutionary process.

Early bats couldn’t fly as fast as they do today.

Over 1200 different species of bats, in their evolutionary process, there is much information that we don’t know. People believe they all have a common ancestor, but we have not yet determined what it is. People also believe that because of differences in location, diet and habitat, various species will branch out. All of this helped them improve their survival.

According to some bat fossils discovered in 2004 and 2008, some bat species have gone extinct. What happened to them and why they couldn’t thrive is another mystery. In this area, there are certainly many things that need to be explored. Many experts hope that with the discovery of more bat fossils, they will get some high-quality answers.
