What animal is the ancestor of the whale Why is the Buckymon the ancestor of the whale?

The whale's ancestor was Bucky, who was born 50 million years ago in the early Eocene. It is a mammal that lives on land all year round. It was the size of a modern fox, looked like a dog, fed mainly on meat, and had a very ferocious temperament.

Scientists believe that huge changes were found in the environment, which allowed Bucky to begin migrating into the water and evolving fin-like limbs, eventually evolving into a type of fish.

What animal are the ancestors of whales?

According to the evolutionary history of cetacean ancestors, the Buckyman originally lived on land near water sources, but later due to external reasons such as environmental upheaval or more abundant food in the water, it was forced to enter the water for food, and finally began to shuttle between land and sea all year round, so that its limbs degraded to adapt to the movement in the water.

Finally, after thousands of years, Bucky finally said goodbye to the land where he had lived for a long time, and threw himself completely into the sea, his limbs completely turned into fins, completely evolved into a mammal that looked like a fish, and even diverged, some evolved into modern dolphins, and some with larger bodies became the largest mammal in the world - the whale. However, the lung structures they use for respiration have not evolved into gills and gills.

Why is Buckymon the ancestor of whales?

The reason why Bucky is considered the ancestor of whales is actually related to some structures in his fossils. Scientists compared the fossils of whales and bucky, and eventually found that although they looked like modern dogs, they had several special bones on their ears, almost the same as those of modern whales, and the same location. This means that they, like whales, have their inner ears that are unable to adapt to the pressure of deep water and need to breathe at the surface frequently.

So it is likely that Bucky lived in the same area as mammals in the early days, and it took a long time for him to gradually turn his tail and limbs into fins, and finally completely degenerate into a fish. The characteristics of mammals, such as viviparity and constant body temperature, are still retained in its body, such as sea lions, seals under fins, and even need to go ashore frequently to breed and live.

The ancestor of the whale was the Buckymon, which was the first mammal to live on land, but as the environment continued to change, the Buckymon evolved into a whale to adapt to the environment.

The ancestor of the whale is the Buckymon, and the main reason why the Buckymon is the ancestor of the whale is verified by the fossils found about the Buckymon by humans, and there are many similarities between them.

The ancestor of the whale is the Buckymon, which was born in the early Eocene 50 million years ago, is a perennial mammal living on land, the size of a modern fox, the shape of a dog, mainly eating meat, very fierce temperament, scientists believe that the environment has found a great change, which made the Buckymon begin to migrate to the water, and evolved fin-like limbs, and eventually evolved into the appearance of a fish.

The ancestor of the whale was the Buckymon. At the beginning of the 21st century, scientists found fossils of two mammals that lived about 50 million years ago in Pakistan. The two animals look a bit like dogs, the size of a wolf and a fox, respectively, but scientists believe it is the ancestor of the largest animal on the planet, the whale, the Buckymon.

Introduction In the early Tertiary period (Late Paleocene and Early Eocene) 5000 to 65 million years ago, all mammals lived on land. Therefore, modern aquatic mammals such as whales and dolphins must have evolved from some terrestrial mammals. However, due to the lack of fossil evidence, the question of which mammal is the ancestor of whales remains unanswered.

The anatomical morphology of the two fossils newly discovered in Pakistan suggests that the animal lived on land, had carnivore teeth, looked like a dog, but did not belong to the canine family. They have longer tails, more ferocious mouths, and smaller eyes than dogs. They have several peculiar bones in their ears that closely resemble bones unique to the same parts of cetaceans.

Indohoss beast or bucky whale.

Whales are mammals from terrestrial animals.

Evolution began 50 million years ago, when they were an artiodactyl mammal of about the same shape, size, and weight as a sheep, called Indojos or Bucky, but they may have been omnivorous or carnivores, and they are the same as today's whales.

as well as dolphins. There are no similarities.

For an unknown reason, they began to tend to live in water, first evolving to resemble otters.

The animals were called land cocobos, migratory whales, and then seals, sea lions.

Walrus, similar to manatees, is called the hardtoothed whale, and it took at least 15 million years for it to evolve from terrestrial to aquatic.

Evolutionary process:

Its evolutionary order is Indohos, Whale, Wandering Whale, Rodhou, Hardtooth Whale, Modern Toothed Whale, and Modern Baleen WhaleTheir evolution and evolution reflect the role of adaptation and natural selection in the theory of evolution, and these evolutions are reflected in their genetic alterations, which have led to the diverse species of cetaceans and dolphins that are now present.

Its body shape is completely different from that of terrestrial mammals, and it has begun to become a streamlined body very similar to that of fish, and it has differentiated into cetaceans and dolphins with very different predation methods and sizes, such as large blue whales, baleen whales, and killer whales.

Because of the loss of genes that inhibit growth, they will continue to grow throughout their lives, usually getting older and getting older.

The ancestor of the whale refers to the Buckymon,Mammals that grow in the ocean, shaped like fish, viviparous, nostrils on the upper part of the head, breathe with lungs, body length can reach thirty meters, is now the largest animal in the world, meat is edible, fat can be used as oil.

Living in the ocean, viviparous, shaped like a large fish, with a body length of up to 30 meters, it is now the largest animal in the world, with fins formed on the forelimbs, completely vestigial on the hind limbs, the tail becomes a tail fin, the nostrils are on the upper part of the head, and it breathes with lungs.

Meat is edible, fat can be made into oil, used in medicine and other industries, such as: blue whale, sperm whale, fin whale, whale (ancient coin name. Cast in the Han Dynasty, it has a fish shape on it, also known as light shadow money.

The earliest ancestors of whales were wolf-sized terrestrial carnivores, which were closely related to some hoofed animals such as cattle, pigs, and antelopes, but their skull features fully prove that they were the ancestors of whales.

The ancestor of the whale was the Buckymon. It was born in the early Eocene 50 million years ago, is a perennial land living mammal, the size of a modern fox, the shape of a dog, mainly meat for food, very fierce temperament, scientists believe that the environment found a great change, which made the buckymon began to migrate to the water, and evolved fin-like limbs, and eventually evolved into the appearance of a fish.

Scientists have compared the fossils of whales and buckymons, and finally found that although they look like modern dogs, they have several special bones in their ears, which are almost the same as modern whales, and the position is the same, which means that it is the same as whales, the inner ear part can not adapt to the deep water pressure, and needs to go to the surface to breathe frequently.

Therefore, it is likely that the buckyman lived in the same area as the mammals in the early days, and eventually gradually changed its tail and limbs into fins after a long time, and finally completely degenerated into the appearance of a fish, but the body still retains the characteristics of mammals, such as viviparity, constant body temperature, etc., such as sea lions and seals under the pinniped order and even need to go ashore often to breed and live.

1. The ancestor of the whale is the Pakistani whale.

At the beginning of the World Ridge Period, scientists found two fossils of mammals that lived about 50 million years ago in Pakistan, these two animals lived on land, had carnivore teeth, looked like dogs, but did not belong to the canine family, there were several peculiar bones in the ears of the caveats, the shape was very similar to the bones unique to the same part of the whale, this animal called the "Pakistani whale" is considered to be the ancestor of the whale.

The ancestor of the whale was the meso-clawed beast. The ancestors of whales were originally terrestrial animals, and then gradually evolved into amphibians, and then into fully aquatic animals, an evolutionary process that began about 50 million years ago, and many branch species evolved from them.

Whales are not fish, but mammals, and the modern blue whale can reach up to 33 meters in length, making it the largest mammal and the largest animal ever living on Earth.

Since the clawed beast was a houngulate in the ancestor of whales, even though the appearance is very different, the hippopotamus is the closest to the whale among modern creatures.

According to the fossils that have been discovered, the first cetaceans to appear were Protocetaea, a transitional species that had evolved breathing holes but still had hind limbs and had strange shapes.

Buckymon.

There have been four groups of early whale fossils from Pakistan that can explain the evolution of whales' ears while adapting to underwater life, and whales from 4300-4600 years ago still have short legs, long tails and long beaks, and some have strong hind limbs, whales at this stage are called Rhode whales, they are considered to be the first whales scattered to the world's tropical oceans, and their common feature is that they have evolved a set of auditory systems that can adapt to underwater life. It laid the foundation for the ultrasonic transmitting and receiving devices that would later evolve.

Then, their front legs gradually degenerate into flippers, and the hind legs and rump disappear, but the tail grows larger and larger, and grows into a fish-like lateral growth, although the posterior skeleton of modern whales still retains traces of the pelvis, and atavism often occurs, such as some newborn whales have hind limbs.

From the above whale evolution, it can be found that the earliest gene is a cloven-hoofed mammal, and its evolutionary sequence is Indohoss whale, whale, wandering whale, Rohod whale, hard-toothed whale, modern toothed whale and modern baleen whale, and its evolution and evolution reflect the role of adaptation and natural selection in the theory of evolution, and these evolutions are reflected in their genetic changes, resulting in the current variety of cetaceans.

Whale habits:

Baleen whales prefer to eat small shrimp because they have no teeth and a small throat, so they cannot chew and can only live by eating small fish and shrimp. The way the baleen whale eats is to first drink a large mouthful of seawater containing small fish and shrimp, and then discharge the seawater after the mouth is closed, and the baleen board is responsible for blocking the small fish and shrimp, and the baleen whale can eat the food into its stomach; Some baleen whales have a more powerful solution, which is that its jaw can be loosened to make the mouth open wider, and in addition, there will be a larynx belly fold in the abdomen of the throat, the number is about 50 to 90, which can make the larynx of the baleen whale expand. These two magic weapons can help baleen whales swallow more seawater and eat more food.

Summary. Supplement; According to the ancestral evolution of whales, it can be known that the Buckymon originally lived on land near the water source, but later due to external reasons such as drastic changes in the environment or more abundant food in the water, it was forced to go into the water to obtain food, and finally began to shuttle between land and sea all year round, so in order to adapt to the movement in the water, its limbs degenerated. Finally, after thousands of years, the buckymon finally bid farewell to the land where it had lived for a long time, and completely devoted itself to the ocean, and its limbs completely changed into fins, completely evolved into a mammal that looks like a fish, and even differentiated, some evolved into modern dolphins, and the other part of the larger body became the world's largest mammal - whales, but their structure of using lungs to breathe did not evolve into gills. Instead, it relies on jumping out of the water from time to time to solve the problem.
