How did bats evolve? What to think of it?

Bats belong to the family of mammals and evolved from the common ancestor of rodents, during which bats developed wing-like forelimbs and gradually developed the ability to fly.

Bats evolved from cells billions of years ago, and billions of years ago all living things were single-celled organisms. Bats are harmful animals because they have too many viruses on them.

Scientists speculate that bats may have evolved from primates, and that lemurs, which have the same gliding ability as bats, have evolved complete limb membranes to glide over long distances. Rats are included in the diet of bats, so to a certain extent they are beneficial to humans and need to be protected.

It is difficult to trace the origin and evolution of bats based on the excavated fossils, because it has been 80 million years since then, but it is by no means a mouse or a bird that has evolved. Bat has the title of the king of poison, it carries a lot of viruses can coexist in some animals, it has a high body temperature and immunity, basically and the virus is safe, some people think that eating bats can also be as poisonous as bats, in fact, many viruses are now infected on a large scale because of it, so for their own health and safety, don't provoke bats, don't eat bats.

Bats, like all mammals, share a common ancestor. With the change of climate and environmental species, there are various species of bats, and bats have viruses on them, but as long as we don't eat it, it will not harm us.

Bats are one of the oldest creatures on Earth, and are the only flying mammals, yes, bats are mammals, and it is this peculiarity that has allowed the bat race to survive the catastrophe. Humans have found bat fossils that are more than 52 million years old, which is almost the same period as the dinosaurs, and it can survive to this day, which is enough to prove the strength of this species.

In our place, many old people say that bats are evolved from mice, and bats are also known as "flying mice" in our local area, bats and mice look very similar, but they have no half-dime relationship, one flies in the sky, one runs on the ground, so this statement is not true. Therefore, the bat has existed on the earth for such a long time, and we have no way of knowing what it evolved, maybe it is still the same ancestor as us humans! The Japanese research team has stated that bats are likely to share the same ancestor as horses and dogs.

About 100 million years ago, bats, horses, and dogs began to evolve differently at about the same time, while cows began their evolutionary process before bats and other animals. But the evolutionary path of bats is really a bit off.

The most well-known characteristic of bats is that they have an anti-natural immune system, bats are out-and-out poison kings, carrying more than 100 kinds of viruses, including the Ebola virus with a very high lethality rate, but the bats themselves are invulnerable, which is the result of thousands of years of evolution, bats seal the virus with their own bodies, and now people still have to eat it, which is tantamount to opening Pandora's box. It may be that from the very beginning, the bat was presented in its current state, it did not evolve from other species, it is it, the bat that cannot be replaced.

Bats, not only terrible in appearance, but also terrible in connotation, its body is a virus reservoir, carrying at least a hundred terrible viruses. For example: Ebola virus, Marburg virus, etc., any one of them is a class A virus.

It evolved from a number of flightless related mammals; Bats also have natural predators, and their natural predators are divided into two types, one is a bird and the other is a snake.

About 100 million years ago, bats belonged to the same class of mammals as horses and dogs, but later with the changes of the times, bats slowly evolved wings to fly in order to survive better; He has natural predators, and his natural predators are lizards, snakes, and felines.

The process of bat evolution:

In the scientific community, there is no specific statement about what bats evolved from, but all mammals should have a common ancestor, and the oldest mammal found so far is the "Archaeopteryx" resume, the fossil of this animal was found in Liaoning, China, and the shape is very similar to a mouse. 65 million years ago, almost all mammalian evolution was in a state of restriction, due to the extinction of the dinosaurs, mammals ushered in the spring and entered a period of rapid evolution.

Bat is the only mammal on the earth that can continue to fly, the forelimbs of the bat are developed, the hind limbs are reduced, so it is difficult for the bat to walk on the ground, and the body is difficult to rely on the hind limbs to support, so the bats are hanging upside down to rest, and the bat will be more convenient to spread its wings when hanging upside down in the high ground, the flexible wings of the bat have excellent mobility, can change the flight angle and direction very quickly, coupled with the bat's unique "echolocation", the bat can quickly and accurately capture the food.

Bats have many benefits for humans, and bats prey on a large number of pests every year, not only to avoid huge losses in agriculture, but also to maintain human health. In addition, many bats also feed on wild fruits and nectar, which is conducive to the fertilization of pollen and the dispersal of seeds, so the value of bats to the ecology is huge.

Although bats still have a large number of viruses themselves, bats rarely come into contact with humans, and bats rarely transmit viruses to other animals. Since bats are the hotbed of viruses, this also reduces the parasitism of viruses on humans and other animals, which is equivalent to bats taking on most of the viruses for us, which is also nature's protection for us, and viruses, bats, and humans coexist in harmony.

But a few people are disrespectful and afraid of nature, to break this balance, to eat bats, which has also led to many viruses raging in the world.

Bats evolved from certain insectivorous mammals in ancient times.

Bats, mammals of the phylum Chordates, are the only class of mammals that have evolved to truly fly. The outer ears of bats protrude forward, move flexibly, have a short neck, broad chest and shoulders, well-developed breasts, and slender hips and legs. They live in all kinds of large and small caves, crevices of ancient buildings, ceilings, partition walls, tree holes, and crevices in rocks on mountains.

Morphological characteristics

The suborder of bats chased by bees is commonly known as bats, and there are 6 families, 26 genera, and 110 species in China. Most bats are insectivorous and carnivorous, and mainly use ultrasonic echolocation signals to search for food, detect distances, determine targets, avoid obstacles and avoid predators.

Bats are truly flying mammals, and this evolutionary advantage allows them to take advantage of a completely new untapped niche in mammals. The wings of bats evolved from their forelimbs in the process of evolution, and are composed of ** (wing membranes) connected between their slender claws; The snout of bats resembles that of a rodent or a fox. The outer ear protrudes forward, is large, and is very flexible in movement.

Bats have short necks, broad thorax and shoulders, well-developed breasts, and slender hips and legs. With the exception of the wing membrane, bats are covered in hairs all over their bodies and have different shades of gray, brownish-yellow, brown, or black on their backs, while their ventral sides are lighter in color.

<>1. Bats evolved from flightless mammals, living in trees all year round about 100 million years ago, like lemurs or squirrels, this animal can jump on the branches, and later, this species has mutated in the sedan chair section, some of these individuals are born with more ** extensions between the arms and the body, which can allow them to jump higher in the air, and the bats that produce this sail shirt mutation have better mobility than other bats, so they are easier to survive and reproduce.

2. In this way, in the process of natural selection, the ** diaphragm between the bat's arm and body becomes wider and wider, and finally evolves into fully functional wings.
