Who are the Bat Ancestors? Why do archaeologists find fossils from 12.5 billion years ago, so why do

In tens of thousands of years of evolution, human beings know very little about prehistoric civilization, only through the study of fossils left behind, although the evolution of human beings is full of various mysteries, but animal evolution, it can be inferred that the Yumen Gansu bird is believed to be the ancestor of birds.

It is not very old from Archaeopteryx, but it has begun to evolve, but the Gansu bird is a twilight bird that tends to the Mesozoic Era, and has no direct close relatives with the primitive dinosaurs, and the discovery of the Gansu bird constitutes an important material evidence for the early evolution of discontinuous birds.

However, in 2006, Chinese paleontologists found a new mammalian fossil in Ningcheng, Inner Mongolia, which has a wing membrane, and the wing membrane is the flight structure of the pterosaur, but this mammal has never been found, and paleontologists have to recreate a species of "ancient Xiang beast" for it.

The ancient Xiangbeast lived 100 million years ago, when it was still the era of dinosaurs, and the discovery of this fossil was 1.5 million years earlier than the Yumen Gansu bird, before it was discovered, bats were considered the world's first flying mammals, and the oldest bats can even be traced back to 51 million years ago.

In appearance, the Ancient Beasts have the characteristics of squirrels and bats, covered with hair, and have wing membranes between their limbs, they can glide freely in the woods, and they even escaped the extinction of the dinosaurs, before the appearance of the Ancient Beasts, paleontologists thought that the large mammals were all extinct, but apparently the Ancient Beasts survived.

The bat fossil found 51 million years ago is the index finger Yishen bat, its winged thumb is short and free, the belt and hind limbs are weak, the snout of the skull is short, the sagittal ridge is developed, the auditory sac is large, the canine teeth are sharp, and the number of teeth varies from 22 to 38, it already has all the characteristics of a bat.

Paleontologists believe that the index finger bat evolved from the insectivorous species of the suborder Pterocarpus or the suborder Pterocarpus, but not many of these two fossils have been found, and the discovery of ancient beasts has provided a way to study.

Paleontologists believe that bats may have evolved from ancient beasts, and even if the ancient beast is not a direct ancestor of bats, it must also be related to bats, such as the false vampire bat, which was initially thought to be a vampire bat, but later discovered that this bat is a predatory invertebrate.

They are very large, about 13 centimeters long in tropical America, they have several species, many of them have no tails, they seem to have a kind of kinship with the ancient beast, but since the ancient beast only has a fossil, it is impossible to provide more evidence.

And there are too many faults between bats and ancient beasts, and it is still difficult for bat ancestors to determine.

Ancient Flying Beast, because this fossil has wing membranes, it is very similar to bats, and it looks terrifying, so it makes people feel chills in the back.

The structure of the Archaeopteryx bats, which lived 32 million years ago, is very similar to some of today's bats, mainly because bats evolved very conservatively, which also shows that their bodies have effective ways to avoid natural predators, such as flight and echolocation, so they do not need to take time to evolve.

Archaeopteryx bats, because there is not much difference, so the previous theories of scientists have been overturned, which makes people feel a chill in their backs.

The ancestor of the bat is the "Gansu bird" that lived in the Cretaceous period hundreds of millions of years ago! But in any case, the "Gansu bird" only has the characteristics of a bird, and its body is covered with feathers rather than fluff. However, the "Ancient Beast" is the same as the current bat, which is also a "non-bird and non-beast".

No, there is no scientific basis at all; Bats and dinosaurs are not the same species, and although the origin of bats has not yet been discovered, it is known that bats are mammals.

The first point is that bats and dinosaurs have no basis for their evolution, and the second point is that it seems to be a special kind of genetically modified and dinosaurs, and there is no basis for specificity.

Yes, because some people have found that bats look more similar to dinosaurs, and the overall skeleton is relatively large, and they like to eat meat.

Not the earliest pterocodactyla fossils found in the Middle Eocene, including the second finger in North America, which is still in a free state, the index finger Ibis bat, and the German tree-like shrew Australopithecus. They belong to two extinction families, and both have intact skeletons and impressions, indicating that they are fully adapted for flight.

The Eocene is the second Paleogene of the Cenozoic Era, about 10 million years later than the Cretaceous dinosaur period, so the earliest bats did not appear in the dinosaur era.

<> is certain that while bats have the ability to fly, they are mammals, so their ancestors could not have been birds. As early as 2006, an archaeological team excavated a fossil of an ancient mammal in the Ningcheng area of Inner Mongolia, according to the research of the archaeological team, the fossil is at least 100 million years old, and may have the ability to glide from the bone structure, and it is even more incredible that this species is likely to be a mammal. For this reason, archaeologists named it the "Ancient Flying Beast" and speculated that it may be related to modern bats.

Archaeologists have found that ancient beasts appeared in the age of dinosaurs.

Not only that, but they also survived the difficult fifth mass extinction, becoming one of the lucky ones in the Cretaceous period. The "Gansu Bird", which is thought to be the ancestor of birds, has been proven to have appeared 1.5 million years later than the ancient Xiangqi, which shows that the ancestors of bats appeared earlier than the ancestors of birds, which also means that there were already bat ancestors in the sky at that time. Until new discoveries were made about the ancestors of bats, the Ancient Beast was considered the only possibility.

So when did the first bats first appear? Before the discovery of the ancient beast, archaeologists believed that the earliest bats should have originated 51 million years ago, and the appearance of the ancient beast convinced archaeologists that the ancestors of bats should have appeared more than 100 million years ago.

However, some paleontologists believe that the direct ancestor of the bat may not have been an ancient beast, and that there may have been a transitional species between the two. As for whether this view is true, it needs to be supported by the emergence of new fossils. Finally, there is another question, it is said that bats carry hundreds of viruses, why can this species survive to this day?

This has a lot to do with the special constitution of bats, which have been studied as high as 40 degrees Celsius, because the metabolic rate in bats is so high that a lot of heat is released.

Most viruses are unable to reproduce properly at such temperatures, so bats are able to carry a wide range of viruses without being affected. In fact, bats are not the only mammal that can fly, there is also a mammal called the flying squirrel. According to zoologists, the body structure of the flying squirrel seems to be a combination of a squirrel and a bat, and although they cannot fly long distances, they are still very good at gliding over short distances.

Why can't flying long distances be made by flying too far? Because they do not have organs in their body structure that are capable of generating lift.

Bats are mammals, so their ancestors could not have been birds. Judging from the fossil skeletal structure found by the archaeological team, it has the ability to glide, and it may also be a mammal, which scientists call the ancient flying beast, which has a lot to do with the ancestors of bats.

The fossils that appeared in Inner Mongolia are ancient beasts, and they are one of the few creatures that survived the five mass extinctions, and they are very likely to be the ancestors of bats.

Paleontologists named this Inner Mongolian creature the Ancient Xiang, and they also believe that it is the ancestor of bats.

Charles Darwin once said, "Natural selection, survival of the fittest". This is the basis for nature's continuous selection and elimination, dinosaurs and bats are two creatures in nature, and nature cannot escape such a law. The extinction of the dinosaurs was the result of natural selection, and the dinosaurs, as the overlords of the earth at that time, could not keep up with the pace of natural selection, so they became extinct.

We can consider these aspects, one is the volume reason; the second is the physiological structure; The third is the struggle of species.

First of all, the dinosaur is by far the largest creature, and he eats a lot in a day. There is a theory about the extinction of dinosaurs that with the change of climate, dinosaurs can no longer find anything to eat, and slowly cannot meet their physiological needs, resulting in a large number of dinosaur groups extinction. The bat is very small compared to the dinosaur, and its food is more complex, and it can eat food in the air and on the ground with the ability to fly, so the bat survived.

Secondly, there is a huge difference between the two physiology. According to the theory of the extinction of the dinosaurs, the earth's temperature dropped dramatically because of the speed of the earth's rotation. For dinosaurs, it was a cold-blooded animal, and it did not have warm fluff on its body, and it could not adapt to the sudden change in climate and froze to death.

But for bats, it has a relatively cold environment, and its wings can wrap its whole body, or fly to a small cave to keep warm.

Third, according to legend, the extinction of the dinosaurs may also be due to the struggle of species, and the emergence of some new mammals ate all the eggs of the dinosaurs, and the dinosaurs slowly became extinct without offspring. The bat moves at night, and the space it lives in is relatively secret, and these mammals cannot find its offspring, so the bat has accumulated a certain number of colonies.

There are many theories about the extinction of dinosaurs and the fact that bats stayed, but in the end, it will be attributed to the fact that dinosaurs were too slow to adapt to nature, bats had wings and could fly to warmer places when the climate changed, and the large-scale migration of dinosaurs was obviously not possible. We have no way of knowing if the bats of ancient times were what they are now, and how are the bats of today not the result of evolution?

Because bats are small in size, they are more conducive to survival in different environments, and they have stronger adaptability than dinosaurs. The size of the dinosaurs was very large and they could survive in that era, but in that catastrophe, the larger the size, the more obvious it was to become a target, so the dinosaurs became extinct, but the bats have survived to the present.

First of all, let me say first, there are a bunch of biologists and dinosaurs crawling black in the comment area here, and they don't know anything and are talking nonsense over there. First of all, the dinosaurs did not go extinct, and there is another kind that has survived to this day and dominated the skies. Secondly, bats appeared later than dinosaurs, about 55 million years ago, and non-avian dinosaurs all became extinct 65 million years ago.

Mammals also died 90 percent of the KPG mass extinctions.

Some bats are small in size, and the space and food requirements for survival are relatively small, but dinosaurs are very large, and once the food ** is reduced, it will cause a large number of dinosaurs to die.

It may be because bats have a strong anti-cancer ability compared to dinosaurs, due to their special DNA distribution, they also have a strong DNA repair ability, and there is one less fragment in the gene, which is completely different from other mammals, so even if cancer invades, he cannot replicate in the bat's body, so most viruses are really helpless to bats.

Personally, I think that bats and dinosaurs are both ancient creatures, so why didn't bats become extinct? Probably because bats are relatively small, and perhaps bats have once appeared as large as large dinosaurs. But for special reasons it disappeared, and the small bat was left behind.

Bats don't need extinction to benefit humans, bats are a link in the food chain, we need them to control insects, spread pollen, etc., extinct bats will also upset the balance of the food chain and the food web.

Because although bats are relatively small, this race is very intelligent, and after several genetic mutations, they are becoming more and more adaptable to the environment.

It's almost there, no one dared to eat them, and now people are going to hunt and eat them one after another, regardless of the virus infection, and they are about to become extinct. However, the Bat King said that before they went extinct, humans might have to go extinct first!

Because the bat is highly reproductive, and its small body is easy to migrate, it is no longer bound by geographical location, and it is easy to find prey that can be hunted.
